The is_enabled implementation is wrong in some cases:
e.g. for pbias_mmc_omap5: emable_mask is : BIT(27) | BIT(25) | BIT(26)
Hi Axel,
s/emable_mask/enable_mask
However, pbias_regulator_enable() only sets BIT(26) | BIT(22) bits.
You mixed up enable_mask of omap5 with .enable of omap4 :-)
above comment should be
"However, pbias_regulator_enable() only sets BIT(27) | BIT(26) bits"
Other than that

So is_enabled callback will always return false in this case.
Fix the logic to compare the register value with info->enable rather than
info->enable_mask.
