Subject: [PATCH linux-next (v3) 1/2] reset: Add brcm,bcm6345-reset device tree
 binding

Add device tree binding for the BCM6345 soft reset controller.

The BCM6345 contains a soft-reset controller activated by setting
a bit (that must previously have been cleared).

Signed-off-by: Simon Arlott <simon@...e.lp0.eu>

v3: Resend. Example has changed because usbh now has two compatible
    strings and uses a power domain instead of a regulator.

v2: Renamed to bcm6345, removed "mask" property.
    Acked-by: Rob Herring <robh@...nel.org>

+Broadcom BCM6345 reset controller
+
+The BCM6345 contains a basic soft reset controller in the perf register
+set which resets components using a bit in a register.
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible:	Should be "brcm,bcm<soc>-reset", "brcm,bcm6345-reset"
+- regmap:	The register map phandle
+- offset:	Offset in the register map for the reset register (in bytes)
+- #reset-cells:	Must be set to 1
+
+Example:
+
+periph_soft_rst: reset-controller {
+	compatible = "brcm,bcm63168-reset", "brcm,bcm6345-reset";
+	regmap = <&periph_cntl>;
+	offset = <0x10>;
+
+	#reset-cells = <1>;
+};
+
+usbh: usbphy@...02700 {
+	compatible = "brcm,bcm63168-usbh", "brcm,bcm6328-usbh";
+	reg = <0x10002700 0x38>;
+	clocks = <&periph_clk 13>, <&timer_clk 18>;
+	resets = <&periph_soft_rst 6>;
+	power-domains = <&misc_iddq_ctrl 4>;
+	#phy-cells = <0>;
+};
