[PATCHv4 7/9] arm: vt8500: doc: Add device tree bindings for arch-vt8500 devices
Tony Prisk

Thu Aug 23 17:35:43 EST 2012
Bindings for gpio, interrupt controller, power management controller,
timer, realtime clock, serial uart, ehci and uhci controllers and
framebuffer controllers used on the arch-vt8500 platform.
Framebuffer binding also specifies a 'display' node which is required
for determining the lcd panel data.

+Device Tree Clock bindings for arch-vt8500
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be one of the following:
+ "via,vt8500-pll-clock" - for a VT8500/WM8505 PLL clock
+ "wm,wm8650-pll-clock" - for a WM8650 PLL clock
+ "via,vt8500-device-clock" - for a VT/WM device clock
+
+Required properties for PLL clocks:
+- reg : shall be the control register offset from PMC base for the pll clock.
+- clocks : shall be the input parent clock phandle for the clock. This should
+ be the reference clock.
+- #clock-cells : from common clock binding; shall be set to 0.
+
+Required properties for device clocks:
+- clocks : shall be the input parent clock phandle for the clock. This should
+ be a pll output.
+- #clock-cells : from common clock binding; shall be set to 0.
+
+
+Device Clocks
+
+Device clocks are required to have one or both of the following sets of
+properties:
+
+
+Gated device clocks:
+
+Required properties:
+- enable-reg : shall be the register offset from PMC base for the enable
+ register.
+- enable-bit : shall be the bit within enable-reg to enable/disable the clock.
+
+
+Divisor device clocks:
+
+Required property:
+- divisor-reg : shall be the register offset from PMC base for the divisor
+ register.
+Optional property:
+- divisor-mask : shall be the mask for the divisor register. Defaults to 0x1f
+ if not specified.
+
+
+For example:
+
+ref25: ref25M {
+ #clock-cells = <0>;
+ compatible = "fixed-clock";
+ clock-frequency = <25000000>;
+};
+
+plla: plla {
+ #clock-cells = <0>;
+ compatible = "wm,wm8650-pll-clock";
+ clocks = <&ref25>;
+ reg = <0x200>;
+};
+
+sdhc: sdhc {
