Subject: [PATCH 3/3] regulator: pbias: Convert to use
 regulator_[enable|is_enabled]_regmap

Since commit ca5d1b3524b4d
"regulator: helpers: Modify helpers enabling multi-bit control",
we can set enable_val setting for device that use multiple bits for control
when using regmap enable/disable/bypass ops.

Note:
This patch depends on below commit which is only in regulator tree now:
http://git.kernel.org/cgit/linux/kernel/git/broonie/regulator.git/commit/?h=topic/enable

I sent this for reveiw and test now.
if it works, I'll resend it once 3.5-rc1 is released.
