target/linux/mvebu/patches-3.8/011-arm_mvebu_add_pin_mux_options_a370.patch

   1 The SDIO interface is available either on pins MPP9/11/12/13/14/15 or
   2 MPP47/48/49/50/51/52 on the Armada 370. Even though all combinations
   3 are potentially possible, those two muxing options are the most
   4 probable ones, so we provide those at the SoC level .dtsi file.
   5
   6 In practice, in turns out the Armada 370 DB board uses the former,
   7 while the Armada 370 Mirabox uses the latter.
