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

Hi Wolfram,

Quoted 11 lines · 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.

Thanks, pushed to mmc-next for .39 now.

- Chris.
