+Binding for Texas Instruments DPLL clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped DPLL with usually two selectable input clocks
+(reference clock and bypass clock), with digital phase locked
+loop logic for multiplying the input clock to a desired output
+clock. This clock also typically supports different operation
+modes (locked, low power stop etc.) This binding has several
+sub-types, which effectively result in slightly different setup
+for the actual DPLL clock.

+
+Required properties:
+- compatible : shall be one of:
+ "ti,omap3-dpll-clock",
+ "ti,omap3-dpll-core-clock",
+ "ti,omap3-dpll-per-clock",
+ "ti,omap3-dpll-per-j-type-clock",
+ "ti,omap4-dpll-clock",
+ "ti,omap4-dpll-x2-clock",
+ "ti,omap4-dpll-core-clock",
+ "ti,omap4-dpll-m4xen-clock",
+ "ti,omap4-dpll-j-type-clock",
+ "ti,omap5-mpu-dpll-clock",
+ "ti,am3-dpll-no-gate-clock",
+ "ti,am3-dpll-j-type-clock",
+ "ti,am3-dpll-no-gate-j-type-clock",
+ "ti,am3-dpll-clock",
+ "ti,am3-dpll-core-clock",
+ "ti,am3-dpll-x2-clock",
+ "ti,omap2-dpll-core-clock",
+
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks, first entry lists reference clock
+ and second entry bypass clock
+- reg : offsets for the register set for controlling the DPLL.
+ Registers are listed in following order:
+ "control" - contains the control register base address
+ "idlest" - contains the idle status register base address
+ "mult-div1" - contains the multiplier / divider register base address
+ "autoidle" - contains the autoidle register base address (optional)
+ "ssc-deltam" - DPLL supports spread spectrum clocking (SSC), contains
+ the frequency spreading register base address (optional)
+ "ssc-modfreq" - DPLL supports spread spectrum clocking (SSC), contains
+ the modulation frequency register base address
+ (optional)
+ ti,am3-* dpll types do not have autoidle register
+ ti,omap2-* dpll type does not support idlest / autoidle registers
+
+Optional properties:
+- DPLL mode setting - defining any one or more of the following overrides
+ default setting.
+ - ti,low-power-stop : DPLL supports low power stop mode, gating output
+ - ti,low-power-bypass : DPLL output matches rate of parent bypass clock
+ - ti,lock : DPLL locks in programmed rate
+ - ti,min-div : the minimum divisor to start from to round the DPLL
+ target rate
+ - ti,ssc-deltam : DPLL supports spread spectrum clocking, frequency
+ spreading in permille (10th of a percent)
+ - ti,ssc-modfreq-hz : DPLL supports spread spectrum clocking, spread
+ spectrum modulation frequency
+ - ti,ssc-downspread : DPLL supports spread spectrum clocking, boolean
+ to enable the downspread feature
