Hi All,
I have a problem with the SDIO support for the CHIPPRo in 4.12 rc2.
The SDHC controller gets found but the WiFi chip does not get
detected.

I'm assuming it's because of the pwrseq_simple probe failing.
If I use the dts file ntc-gr8-crumb.dts for the ntc 4.4.30 kernel the
SDIO WiFi does get detected.
Sorry this is a side effect of reverting the sunxi clock changes to get
the NAND working. Without the clock changes the SDIO card gets found.
