[U-Boot] [PATCH 0/2] Enable usage of PCF GPIO line as regulator

[Vignesh R]

Some IPs like MMC use PCF GPIO lines as fixed regulator, hence add
support for the same.

[U-Boot] [PATCH 1/2] ARM: dts: dra7xx-evm: add evm_3v3_sd regulator

[Vignesh R]

Add a node for evm_3v3_sd using onboard PCF GPIO expander which feeds
on to mmc vdd.
Update mapping for vmmc-supply and vmmc_aux-supply.
evm_3v3_sd supplies to SD card vdd, and ldo1 to sdcard i/o lines.

[U-Boot] [PATCH 2/2] ARM: dra7xx_evm: Enable regulator DM support

[Vignesh R]

Enable DM based regulator framework and also fixed regulator support as
some IPs like mmc use regulators for there functioning.
