[PATCH v4 0/8] Add power-supply properties for sdmmc nodes on Microchip boards

[Mihai Sain]

This patch series adds power-supply properties for sdmmc nodes on Microchip boards.

Changes in v4:
--------------

* Simplify the commit description for each board to have a better understanding.

Changes in v3:
--------------

* Update the commit description for each board in order to wrap the line at max 75 columns.

Changes in v2:
--------------

* Update the commit description for each board.
* The goal is to keep the vqmmc at 3V3 in order to use the sd high-speed mode.
