Define the SILK board dependent parts of the SDHI0 (connected to SDIO Wi-Fi chip) and SDHI1 (connected to micro-SD slot) device nodes along with the necessary voltage regulators.

Thanks for your patch. One question - above you write that SDHI1 is micro-SD...
Yes, have double-checked now.

... 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. =)
Both seem correct: SD1_WP signal is just tied to VCCQ_SD1. Do you think we should still drop it?
Also, I doubt that an on-board SDIO module makes use of CD and/or WP signals?
Those two are tied to VCCQ_SD0 as well. Do you think we should drop them?
Thanks, / magnus
