This adds a new binding for the gate clocks present in the CFGCHIP syscon
registers in TI DA8XX SoCs. There are actually other gate clocks in this
block that could be added in the future, but TBCLK is currently the only
one being used.

+Binding for TI DA8XX/OMAP-L13X/AM17XX/AM18XX CFGCHIP gate clocks
+
+TI DA8XX/OMAP-L13X/AM17XX/AM18XX SoCs contain a general purpose set of
+registers call CFGCHIPn. Some of these registers function as clock
+gates. This document describes the bindings for those clocks.
+
+Required properties:
+- compatible: shall be "ti,da830-tbclk".
+- #clock-cells: from common clock binding; shall be set to 0.
+- clocks: phandle to the parent clock
+
+Optional properties:
+- clock-output-names: from common clock binding.
+
+Parent:
+This node must be a child of a "ti,da830-cfgchip" node.
+
+Assignment:
+The assigned-clocks and assigned-clock-parents from the common clock bindings
+can be used to indicate which parent clock should be used.
+
+Examples:
+
+ cfgchip: syscon@1417c {
+ compatible = "ti,da830-cfgchip", "syscon", "simple-mfd";
+ reg = <0x1417c 0x14>;
+
+ ehrpwm_tbclk: tbclk {
+ compatible = "ti,da830-tbclk";
+ #clock-cells = <0>;
+ clocks = <&psc1 17>;
+ clock-output-names = "ehrpwm_tbclk";
+ };
+ };
