[PATCH 0/5] sdhci-esdhc-imx: use gpio for write protection and card detection

[Wolfram Sang]

Hi,

I finally could do a second version of my write protect-patches and the first
version of a card detect approach (thanks to Olof for the inspiration here).
Note that these feature are only needed for i.mx25/35 as the i.mx5x-series
_finally_ seem to be able to route the gpios to the controller directly.

These patches apply to mmc-next and have been tested with a mx35-based pcm043.
I think the first three patches should go via Chris and the latter two via
Sascha. The last one is more a cleanup-patch, but it depends on the former, so
I included it here.

The branch can be found at:

	git://git.pengutronix.de/git/wsa/linux-2.6.git pcm043-mmc

Eric: Would be awesome if you could test these on your boards!

Looking forward to comments,

   Wolfram
