From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

commit a8a47540ebe32f1733eebc3e5699af580ceaa3f5 upstream.

This patch adds support to list_voltage callback, so that consumers
like mmc core, can get information of supported voltage range.

Without this patch there is no way for mmc core to know this voltage range.

There's a subsequent patch, 43160ffd12 (regulator: qcom_smd: Remove
list_voltage callback for rpm_smps_ldo_ops_fixed) which is also needed
for some of the users (this was only reported to me a couple of hours
ago so I've still not sent that patch to Linus yet, should happen
tomorrow).  That looks like a cleanup but in fact fixes some booting
issues that some devices see.

Ok, if it lands tomorrow or so, that should be fine, I'm not counting on
doing a stable release for the next few days at the earliest.
