Hm, no, this is not the whole truth: this will leave both SDHI0 and SDHI2
slots unpowered is the fixed regulator is unavailable. This shall only be
applied after we "select CONFIG_REGULATOR_FIXED_VOLTAGE" so, don't think
we want this for 3.6. Still would be nice to know, whether those GPIOs can
be used for power switching at all.
Thanks

Hello, Guennadi
This is Tetsuyuki Kobayashi. I have a KZM-A9-GT board (kzm9g).
According to the board specification (written in Japanese),
GPIOs 15 and 14 are connected to VDD of connector through PowerSW,
resptctively.
I tried this patch with CONFIG_REGULATOR_FIXED_VOLTAGE=y, But
both SD card and micro SD card are not recognized (as if they are
not inserted).
I guess something missing. Please tell me how to test this patch
so that I will try again.

Great, thanks for confirming!

Thanks for testing. Yes, these ARM patches are preparatory, they cannot
work without respective counterparts in the mmc driver subsystem. At the
very least you also need these patches:
http://www.spinics.net/lists/linux-sh/msg12007.html
http://www.spinics.net/lists/linux-sh/msg12160.html
but at least the latter of them might not apply cleanly to your tree. It
might be easier to test if you pull in the mmc-next branch of
git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc.git
Thanks
