Subject: [PATCH] dt-bindings: fsl: convert fsl,layerscape-scfg to YAML
Date:   Thu, 21 Apr 2022 17:31:15 +0200
Message-Id: <20220421153115.3496834-1-michael@walle.cc>
X-Mailer: git-send-email 2.30.2
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

Convert the fsl,layerscape-scfg binding to the new YAML format.

Added, compared to the original binding, is the interrupt-controller
subnode as used in arch/arm/boot/dts/ls1021a.dtsi as well as the
litte-endian and big-endian properties.

-Freescale SCFG
-
-SCFG is the supplemental configuration unit, that provides SoC specific
-configuration and status registers for the chip. Such as getting PEX port
-status.
-
-Required properties:
-  - compatible: Should contain a chip-specific compatible string,
-	Chip-specific strings are of the form "fsl,<chip>-scfg",
-	The following <chip>s are known to be supported:
-	ls1012a, ls1021a, ls1043a, ls1046a, ls2080a.
-
-  - reg: should contain base address and length of SCFG memory-mapped registers
-
-Example:
-	scfg: scfg@1570000 {
-		compatible = "fsl,ls1021a-scfg";
-		reg = <0x0 0x1570000 0x0 0x10000>;
-	};
