[PATCH V4 0/3] adding write_protect and card_detect for mx25/35

[w.sang@pengutronix.de (Wolfram Sang)]

Last tests showed some problems with MX51, especially with card_detect. While
the approach in general will suffice for i.MX5x, it seems there are a few
details missing right now. Because I do not have the resources (both time and
hardware) to deal with these issues, I propose a step by step approach. Let's
add the functionality for mx25/35 first and make sure there is no difference in
behaviour for mx5x. (Note that the i.MX5x can route the pins directly to the
controller, so a properly designed board should not need these gpio-additions.)
That is what this patch series does: The main change is that mx5x won't notice
any difference. For mx25/35, it is the same as it has been tested by Eric and
Marc.

Thanks to all involved in providing feedback, I hope it can go in now. If you
want to add support for it to your board, please CC me.

Have a nice weekend,
