-Subject: [PATCH 09/11] MIPS: BCM63XX: add support for the on-chip EHCI
- controller
-
-Broadcom BCM63XX SoCs include an on-chip EHCI controller which can be
-driven by the generic ehci-platform driver by using specific power
-on/off/suspend callbacks to manage clocks and hardware specific
-configuration.
