The next step in modernization of GPIO is to let drivers handle
descriptors rather than integer numbers representing GPIO pins,
akin to how clocks or regulators are already handled today.
This patch makes the MMCI driver use GPIO descriptos in the
core code with fallback code using the platform

The is_enabled implementation is wrong in some cases:
e.g. for pbias_mmc_omap5: enable_mask is : BIT(27) | BIT(25) | BIT(26)
However, pbias_regulator_enable() only sets BIT(27) |

I have seen some patches around lately touching the code for handling
the regulators (vcc and vccq) in sdhci.
Was it this patch you were thinking of or something else?

Looking at it now.
