[PATCH 1/2] ARM:mach-mx5/board-mx51_babbage: Add CD and WP GPIOs

From: Shawn Guo <hidden>
Date: 2011-06-29 12:44:59

Hi Sascha,

Just let you know that SD/MMC driver on your for-next is broken for
all mx5 based boards, because adding esdhc platform data for mx5 will
get sdhci-esdhc-imx driver probe function fail on "goto not_supported".

Hopefully, Chris will get the series below applied soon, which will
get the driver back to work for mx5.

  [PATCH v4 0/4] Extend sdhci-esdhc-imx card_detect and write_protect
  support for mx5

Regards,
Shawn
