target/linux/mvebu/patches-3.8/012-arm_mvebu_add_pin_mux_options_axp.patch

   1 The SDIO interface is only available on pins MPP30/31/32/33/34/35 on
   2 the various Armada XP variants, so we provide a pin muxing option for
   3 this in the Armada XP .dtsi files.
   4
   5 Even though those muxing options are the same for MV78230, MV78260 and
   6 MV78460, we keep them in each .dtsi file, because the number of pins,
   7 and therefore the declaration of the pinctrl node, is different for
   8 each SoC variant.
