Subject: [PATCH v2 16/19] dt-bindings: img-ascii-lcd: Document a binding for simple ASCII LCDs
Date: Fri, 26 Aug 2016 15:17:48 +0100 [thread overview]
Message-ID: <20160826141751.13121-17-paul.burton@imgtec.com> (raw)
In-Reply-To: <20160826141751.13121-1-paul.burton@imgtec.com>
Add documentation for a devicetree binding for the simple ASCII LCD
displays found on development boards such as the MIPS Boston, MIPS Malta
& MIPS SEAD3 from Imagination Technologies.
Signed-off-by: Paul Burton <paul.burton@imgtec.com>

+Binding for ASCII LCD displays on Imagination Technologies boards
+
+Required properties:
+- compatible : should be one of:
+ "img,boston-lcd"
+ "mti,malta-lcd"
+ "mti,sead3-lcd"
+
+Required properties for "img,boston-lcd":
+- reg : memory region locating the device registers
+
+Required properties for "mti,malta-lcd" or "mti,sead3-lcd":
+- regmap: phandle of the system controller containing the LCD registers
+- offset: offset in bytes to the LCD registers within the system controller
+
+The layout of the registers & properties of the display are determined
+from the compatible string, making this binding somewhat trivial.
