Subject: [PATCH v4 5/7] dt-bindings: sram: Merge Rockchip SRAM bindings into generic
Date: Mon, 21 Oct 2019 18:13:49 +0200	[thread overview]
Message-ID: <20191021161351.20789-5-krzk@kernel.org> (raw)
In-Reply-To: <20191021161351.20789-1-krzk@kernel.org>

The Rockchip SRAM bindings list only compatible so integrate them into
generic SRAM bindings schema.

-Rockchip SRAM for smp bringup:
-------------------------------
-
-Rockchip's smp-capable SoCs use the first part of the sram for the bringup
-of the cores. Once the core gets powered up it executes the code that is
-residing at the very beginning of the sram.
-
-Therefore a reserved section sub-node has to be added to the mmio-sram
-declaration.
-
-Required sub-node properties:
-- compatible : should be "rockchip,rk3066-smp-sram"
-
-The rest of the properties should follow the generic mmio-sram discription
-found in Documentation/devicetree/bindings/sram/sram.txt
-
-Example:
-
-	sram: sram@10080000 {
-		compatible = "mmio-sram";
-		reg = <0x10080000 0x10000>;
-		#address-cells = <1>;
-		#size-cells = <1>;
-		ranges;
-
-		smp-sram@10080000 {
-			compatible = "rockchip,rk3066-smp-sram";
-			reg = <0x10080000 0x50>;
-		};
-	};
