Subject: [RFC PATCH v2 1/2] dt-bindings: sram: convert rockchip-pmu-sram bindings to yaml

Current dts files with 'rockchip-pmu-sram' compatible nodes
are now verified with sram.yaml, although the original
text document still exists. Merge rockchip-pmu-sram.txt
with sram.yaml by adding it as description with an example.

Signed-off-by: Johan Jonker <jbx6244@...il.com>

Not tested with hardware.

Changed v2:
  Merge with sram.yaml

-Rockchip SRAM for pmu:
-------------------------------
-
-The sram of pmu is used to store the function of resume from maskrom(the 1st
-level loader). This is a common use of the "pmu-sram" because it keeps power
-even in low power states in the system.
-
-Required node properties:
-- compatible : should be "rockchip,rk3288-pmu-sram"
-- reg : physical base address and the size of the registers window
-
-Example:
-	sram@...20000 {
-		compatible = "rockchip,rk3288-pmu-sram", "mmio-sram";
-		reg = <0xff720000 0x1000>;
-	};
