+Subject: [PATCH 18/73] NET: MIPS: lantiq: make etop ethernet work on ase/ar9
+
+Extend the driver to handle the different DMA channel layout for AR9 and
+Amazon-SE SoCs. The patch also adds support for the integrated PHY found
+on Amazon-SE and the gigabit switch found inside the AR9.

-Extend the driver to handle the different DMA channel layout for AR9 and
-Amazon-SE SoCs. The patch also adds support for the integrated PHY found
-on Amazon-SE and the gigabit switch found inside the AR9.

-
-On Falcon SoCs we have a secondary serial port that can be used to help
-debug the voice core. For the port to work several clocking bits need to
-be activated. We convert the code to clkdev api.

+Subject: [PATCH 38/73] SPI: MIPS: lantiq: add FALC-ON spi driver
+
+The external bus unit (EBU) found on the FALC-ON SoC has spi emulation that is
+designed for serial flash access. This driver has only been tested with m25p80
+type chips. The hardware has no support for other types of spi peripherals.

-Subject: [PATCH 39/70] SPI: MIPS: lantiq: add FALC-ON spi driver
-
-The external bus unit (EBU) found on the FALC-ON SoC has spi emulation that is
-designed for serial flash access. This driver has only been tested with m25p80
-type chips. The hardware has no support for other types of spi peripherals.

+Subject: [PATCH 40/73] MIPS: lantiq: add xway nand driver
+
+This patch adds a nand driver for XWAY SoCs. The patch makes use of the
+plat_nand driver. As with the EBU NOR driver merged in 3.0, we have the
+endianess swap problem on read. To workaround this problem we make the
+read_byte() callback available via the plat_nand driver causing the nand
+layer to do byte reads.

++ * The Core Interface Layer provides basic services for accessing and

++ * Host Controller Driver and the Peripheral Controller Driver.
++ *
++ * The CIL manages the memory map for the core so that the HCD and PCD
++ * don't have to do this separately. It also handles basic tasks like
++ * reading/writing the registers and data FIFOs in the controller.
++ * Some of the data access functions provide encapsulation of several
++ * operations required to perform a task, such as writing multiple
++ * registers to start a transfer. Finally, the CIL performs basic
++ * services that are not specific to either the host or device modes
++ * of operation. These services include management of the OTG Host
++ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
++ * Diagnostic API is also provided to allow testing of the controller
++ * hardware.
++ *
++ * The Core Interface Layer has the following requirements:
++ * - Provides basic controller operations.
++ * - Minimal use of OS services.
++ * - The OS services used will be abstracted by using inline functions
++ * or macros.

++ * removed (using rmmod), the dwc_otg_cleanup function is called.
++ *
++ * This module also defines a data structure for the dwc_otg_driver, which is
++ * used in conjunction with the standard ARM lm_device structure. These
++ * structures allow the OTG driver to comply with the standard Linux driver
++ * model in which devices and drivers are registered with a bus driver. This
++ * has the benefit that Linux can expose attributes of the driver and device
++ * in its special sysfs file system. Users can then read or write files in
++ * this file system to perform diagnostics on the driver components or the
++ * device.

-+ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
-+ * Diagnostic API is also provided to allow testing of the controller
-+ * hardware.

-+ * The dwc_otg_driver module provides the initialization and cleanup entry
-+ * points for the DWC_otg driver. This module will be dynamically installed
-+ * after Linux is booted using the insmod command. When the module is
-+ * installed, the dwc_otg_init function is called. When the module is
-+ * removed (using rmmod), the dwc_otg_cleanup function is called.
-+ *
-+ * This module also defines a data structure for the dwc_otg_driver, which is
-+ * used in conjunction with the standard ARM lm_device structure. These
-+ * structures allow the OTG driver to comply with the standard Linux driver
-+ * model in which devices and drivers are registered with a bus driver. This
-+ * has the benefit that Linux can expose attributes of the driver and device
-+ * in its special sysfs file system. Users can then read or write files in
-+ * this file system to perform diagnostics on the driver components or the
-+ * device.

++ \brief This function trigger a data transfer for a host channel and

++
++ For a PING transfer in Slave mode, the Do Ping bit is set in the HCTSIZ
++ register along with a packet count of 1 and the channel is enabled. This
++ causes a single PING transaction to occur. Other fields in HCTSIZ are
++ simply set to 0 since no data transfer occurs in this case.
++
++ For a PING transfer in DMA mode, the HCTSIZ register is initialized with
++ all the information required to perform the subsequent data transfer. In
++ addition, the Do Ping bit is set in the HCTSIZ register. In this case, the
++ controller performs the entire PING protocol, then starts the data
++ transfer.
++ \param _core_if Pointer of core_if structure
++ \param _ifxhc Information needed to initialize the host channel. The xfer_len
++ value may be reduced to accommodate the max widths of the XferSize and
++ PktCnt fields in the HCTSIZn register. The multi_count value may be changed
++ to reflect the final xfer_len value.

++ \brief A URB Descriptor (URBD) holds the state of a bulk, control,

++ (of one of these types) submitted to the HCD. The transfer associated with
++ a URBD may require one or multiple transactions.
++
++ A URBD is linked to a EP Queue Head, which is entered in either the
++ isoc, intr or non-periodic schedule for execution. When a URBD is chosen for
++ execution, some or all of its transactions may be executed. After
++ execution, the state of the URBD is updated. The URBD may be retired if all
++ its transactions are complete or if an error occurred. Otherwise, it
++ remains in the schedule so more transactions can be executed later.

++ //dev Identifies the USB device to perform the request.

++ // eventually replace pipe.
++ //pipe Holds endpoint number, direction, type, and more.
++ // Create these values with the eight macros available; u
++ // sb_{snd,rcv}TYPEpipe(dev,endpoint), where the TYPE is
++ // "ctrl", "bulk", "int" or "iso". For example
++ // usb_sndbulkpipe or usb_rcvintpipe. Endpoint numbers
++ // range from zero to fifteen. Note that "in" endpoint two
++ // is a different endpoint (and pipe) from "out" endpoint
++ // two. The current configuration controls the existence,
++ // type, and maximum packet size of any given endpoint.
++ //status This is read in non-iso completion functions to get
++ // the status of the particular request. ISO requests
++ // only use it to tell whether the URB was unlinked;
++ // detailed status for each frame is in the fields of
++ // the iso_frame-desc.
++ //transfer_flags A variety of flags may be used to affect how URB
++ // submission, unlinking, or operation are handled.
++ // Different kinds of URB can use different flags.
++ // URB_SHORT_NOT_OK
++ // URB_ISO_ASAP
++ // URB_NO_TRANSFER_DMA_MAP
++ // URB_NO_SETUP_DMA_MAP
++ // URB_NO_FSBR
++ // URB_ZERO_PACKET
++ // URB_NO_INTERRUPT
++ //transfer_buffer This identifies the buffer to (or from) which the I/O
++ // request will be performed (unless URB_NO_TRANSFER_DMA_MAP
++ // is set). This buffer must be suitable for DMA; allocate it
++ // with kmalloc or equivalent. For transfers to "in"
++ // endpoints, contents of this buffer will be modified. This
++ // buffer is used for the data stage of control transfers.
++ //transfer_dma When transfer_flags includes URB_NO_TRANSFER_DMA_MAP, the
++ // device driver is saying that it provided this DMA address,
++ // which the host controller driver should use in preference
++ // to the transfer_buffer.
++ //transfer_buffer_length How big is transfer_buffer. The transfer may be broken
++ // up into chunks according to the current maximum packet size
++ // for the endpoint, which is a function of the configuration
++ // and is encoded in the pipe. When the length is zero, neither
++ // transfer_buffer nor transfer_dma is used.
++ //actual_length This is read in non-iso completion functions, and it tells
++ // how many bytes (out of transfer_buffer_length) were transferred.
++ // It will normally be the same as requested, unless either an error
++ // was reported or a short read was performed. The URB_SHORT_NOT_OK
++ // transfer flag may be used to make such short reads be reported
++ // as errors.
++ //setup_packet Only used for control transfers, this points to eight bytes of
++ // setup data. Control transfers always start by sending this data
++ // to the device. Then transfer_buffer is read or written, if needed.
++ //setup_dma For control transfers with URB_NO_SETUP_DMA_MAP set, the device
++ // driver has provided this DMA address for the setup packet. The
++ // host controller driver should use this in preference to setup_packet.
++ //start_frame Returns the initial frame for isochronous transfers.
++ //number_of_packets Lists the number of ISO transfer buffers.
++ //interval Specifies the polling interval for interrupt or isochronous transfers.
++ // The units are frames (milliseconds) for for full and low speed devices,
++ // and microframes (1/8 millisecond) for highspeed ones.
++ //error_count Returns the number of ISO transfers that reported errors.
++ //context For use in completion functions. This normally points to request-specific
++ // driver context.
++ //complete Completion handler. This URB is passed as the parameter to the completion
++ // function. The completion function may then do what it likes with the URB,
++ // including resubmitting or freeing it.

++ \brief This function does the setup for a data transfer for a host channel and
++ starts the transfer. May be called in either Slave mode or DMA mode. In
++ Slave mode, the caller must ensure that there is sufficient space in the
++ request queue and Tx Data FIFO.
++
++ For an OUT transfer in Slave mode, it loads a data packet into the
++ appropriate FIFO. If necessary, additional data packets will be loaded in
++ the Host ISR.
++
++ For an IN transfer in Slave mode, a data packet is requested. The data
++ packets are unloaded from the Rx FIFO in the Host ISR. If necessary,
++ additional data packets are requested in the Host ISR.
++
++ For a PING transfer in Slave mode, the Do Ping bit is set in the HCTSIZ
++ register along with a packet count of 1 and the channel is enabled. This
++ causes a single PING transaction to occur. Other fields in HCTSIZ are
++ simply set to 0 since no data transfer occurs in this case.
++
++ For a PING transfer in DMA mode, the HCTSIZ register is initialized with
++ all the information required to perform the subsequent data transfer. In
++ addition, the Do Ping bit is set in the HCTSIZ register. In this case, the
++ controller performs the entire PING protocol, then starts the data
++ transfer.
++
++ @param _ifxhc Information needed to initialize the host channel. The xfer_len
++ value may be reduced to accommodate the max widths of the XferSize and
++ PktCnt fields in the HCTSIZn register. The multi_count value may be changed
++ to reflect the final xfer_len value.

++ ** dynamically loaded with insmod command or built-in
++ ** with kernel. When loaded or executed the ifxusb_driver_init
++ ** function is called. When the module is removed (using rmmod),
++ ** the ifxusb_driver_cleanup function is called.

++ ** FILE NAME : ifxusb_regs.h
++ ** PROJECT : IFX USB sub-system V3
++ ** MODULES : IFX USB sub-system Host and Device driver
++ ** SRC VERSION : 1.0
++ ** DATE : 1/Jan/2009
++ ** AUTHOR : Chen, Howard
++ ** DESCRIPTION : This file contains the data structures for accessing the IFXUSB core
++ ** registers.
++ ** The application interfaces with the USB core by reading from and
++ ** writing to the Control and Status Register (CSR) space through the
++ ** AHB Slave interface. These registers are 32 bits wide, and the
++ ** addresses are 32-bit-block aligned.
++ ** CSRs are classified as follows:
++ ** - Core Global Registers
++ ** - Device Mode Registers
++ ** - Device Global Registers
++ ** - Device Endpoint Specific Registers
++ ** - Host Mode Registers
++ ** - Host Global Registers
++ ** - Host Port CSRs
++ ** - Host Channel Specific Registers
++ **
++ ** Only the Core Global registers can be accessed in both Device and
++ ** Host modes. When the USB core is operating in one mode, either
++ ** Device or Host, the application must not access registers from the
++ ** other mode. When the core switches from one mode to another, the
++ ** registers in the new mode of operation must be reprogrammed as they
++ ** would be after a power-on reset.

-+ ** FILE NAME : ifxusb_regs.h
-+ ** PROJECT : IFX USB sub-system V3
-+ ** MODULES : IFX USB sub-system Host and Device driver
-+ ** SRC VERSION : 1.0
-+ ** DATE : 1/Jan/2009
-+ ** AUTHOR : Chen, Howard
-+ ** DESCRIPTION : This file contains the data structures for accessing the IFXUSB core
-+ ** registers.
-+ ** The application interfaces with the USB core by reading from and
-+ ** writing to the Control and Status Register (CSR) space through the
-+ ** AHB Slave interface. These registers are 32 bits wide, and the
-+ ** addresses are 32-bit-block aligned.
-+ ** CSRs are classified as follows:
-+ ** - Core Global Registers
-+ ** - Device Mode Registers
-+ ** - Device Global Registers
-+ ** - Device Endpoint Specific Registers
-+ ** - Host Mode Registers
-+ ** - Host Global Registers
-+ ** - Host Port CSRs
-+ ** - Host Channel Specific Registers
-+ **
-+ ** Only the Core Global registers can be accessed in both Device and
-+ ** Host modes. When the USB core is operating in one mode, either
-+ ** Device or Host, the application must not access registers from the
-+ ** other mode. When the core switches from one mode to another, the
-+ ** registers in the new mode of operation must be reprogrammed as they
-+ ** would be after a power-on reset.

+Subject: [PATCH 55/73] MIPS: lantiq: make GPIO3 work on AR9
+
+There are 3 16bit and 1 8bit gpio ports on AR9. The gpio driver needs a hack
+at 2 places to make the different register layout of the GPIO3 work properly
+with the driver. Before only GPIO0-2 were supported. As the GPIO number scheme
+clashes with the new size, we also move the other gpio chips to new offsets.

-Subject: [PATCH 56/70] MIPS: lantiq: make GPIO3 work on AR9
-
-There are 3 16bit and 1 8bit gpio ports on AR9. The gpio driver needs a hack
-at 2 places to make the different register layout of the GPIO3 work properly
-with the driver. Before only GPIO0-2 were supported. As the GPIO number scheme
-clashes with the new size, we also move the other gpio chips to new offsets.

++ IFX extension for reserving (splitting) cache ways among VPEs. You must
++ give kernel command line arguments vpe_icache_shared=0 or
++ vpe_dcache_shared=0 to enable splitting of icache or dcache
++ respectively. Then you can specify which cache ways should be
++ assigned to which VPE. There are total 8 cache ways, 4 each
++ for dcache and icache: dcache_way0, dcache_way1,dcache_way2,
++ dcache_way3 and icache_way0,icache_way1, icache_way2,icache_way3.
++
++ For example, if you specify vpe_icache_shared=0 and icache_way2=1,
++ then the 3rd icache way will be assigned to VPE0 and denied in VPE1.
++
++ For icache, software is required to make at least one cache way available
++ for a VPE at all times i.e., one can't assign all the icache ways to one
++ VPE.
++
++ By default, vpe_dcache_shared and vpe_icache_shared are set to 1
++ (i.e., both icache and dcache are shared among VPEs)

-+ IFX extension for reserving (splitting) cache ways among VPEs. You must
-+ give kernel command line arguments vpe_icache_shared=0 or
-+ vpe_dcache_shared=0 to enable splitting of icache or dcache
-+ respectively. Then you can specify which cache ways should be
-+ assigned to which VPE. There are total 8 cache ways, 4 each
-+ for dcache and icache: dcache_way0, dcache_way1,dcache_way2,
-+ dcache_way3 and icache_way0,icache_way1, icache_way2,icache_way3.
-+
-+ For example, if you specify vpe_icache_shared=0 and icache_way2=1,
-+ then the 3rd icache way will be assigned to VPE0 and denied in VPE1.
-+
-+ For icache, software is required to make at least one cache way available
-+ for a VPE at all times i.e., one can't assign all the icache ways to one
-+ VPE.
-+
-+ By default, vpe_dcache_shared and vpe_icache_shared are set to 1
-+ (i.e., both icache and dcache are shared among VPEs)

+Subject: [PATCH 71/73] MIPS: lantiq: stp, fix for ase, add get, clock
+ disabled
+
+Lantiq serial-to-parallel hardware gpio module
+Added gpio pins as used for amazon se (ase)
+Added get to enable reporting of gpio status
+Changed to use software update, as hw clock was not running on ase. Clock
+really only needed if hw flashing was implemented.

+ platform driver
+
+irqs, gpios, chipselects
+updated to use module_platform_driver()
+clkdev is a bit hacky, using ltq_spi.0, as specifying no device numbering led to
+the mtd driver not hooking up to an spi flash.
