From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> Add properties to describe the reset topology for on-SoC devices: - Add the "#reset-cells" property to the CPG/MSSR device node, - Add resets and reset-names properties to the various device nodes. This allows to reset SoC devices using the Reset Controller API. Note that resets usually match the corresponding module clocks. Exceptions are: - The audio module has resets for the Serial Sound Interfaces only, - The display module has only a single reset for all DU channels, but adding reset properties for the display is postponed.
