Subject: [PATCH v2 2/6] mfd: dt: Add bindings for the Aspeed SoC Display Controller (GFX)
Date: Thu, 3 Nov 2016 01:07:57 +1030 [thread overview]
Message-ID: <1478097481-14895-3-git-send-email-andrew@aj.id.au> (raw)
In-Reply-To: <1478097481-14895-1-git-send-email-andrew@aj.id.au>
The Aspeed SoC Display Controller is presented as a syscon device to
arbitrate access by display and pinmux drivers. Video pinmux
configuration on fifth generation SoCs depends on bits in both the
System Control Unit and the Display Controller.

+* Device tree bindings for Aspeed SoC Display Controller (GFX)
+
+The Aspeed SoC Display Controller primarily does as its name suggests, but also
+participates in pinmux requests on the g5 SoCs. It is therefore considered a
+syscon device.
+
+Required properties:
+- compatible: "aspeed,ast2500-gfx", "syscon"
+- reg: contains offset/length value of the GFX memory
+ region.
+
+Example:
+
+gfx: display@1e6e6000 {
+ compatible = "aspeed,ast2500-gfx", "syscon";
+ reg = <0x1e6e6000 0x1000>;
+};
