Revision 879d68a445dd7073a8c022fcdd21dc27eca7f192 authored by Ryan Press on 26 March 2013, 23:32:31 UTC, committed by Jason Cooper on 28 March 2013, 17:29:23 UTC
The previous configuration used the wrong "clk" pin. Without this change mv_sdio worked because the bootloader would set the pin up, but with a bootloader that does not set the pin, mv_sdio fails to detect any card. I have tested this change using a mwifiex_sdio wireless network adapter over the SDIO interface. Signed-off-by: Ryan Press <ryan@presslab.us> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
