From 615beb759ca494a4b1a202f571af41549064dc2f Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 11 Sep 2017 15:09:59 +0200 Subject: [PATCH] ARM: dts: r8a7794: Add reset control properties 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.
