I'm wondering how you tested the patches, as CD and WP has not been
supported by sdhci-esdhc-imx driver yet.

PS. I'm adding the support with the patch set below.

[PATCH 0/4] Extend sdhci-esdhc-imx card_detect and write_protect
support for mx5
Shawn Guo June 29, 2011, 12:44 p.m. UTC | #2
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
