Thanks for your patch. One question - above you write that SDHI1 is micro-SD...

... however here the WP signal is assigned.
I believe micro-SD doesn't use the WP signal, so either I'm wrong or
the patch needs to be updated to reflect reality. =)
Also, I doubt that an on-board SDIO module makes use of CD and/or WP signals?
Any ideas?
Thanks,
