clk: TI CDCE706 clock synthesizer driver

The driver allows using CDCE706 in its default configuration recorded in
EEPROM and adjusting of synthesized clocks by consumers.

Bindings for Texas Instruments CDCE706 programmable 3-PLL clock
synthesizer/multiplier/divider.
Reference: http://www.ti.com/lit/ds/symlink/cdce706.pdf
I2C device node required properties:
- compatible: shall be "ti,cdce706".
- reg: i2c device address, shall be in range [0x68...0x6b].
- #clock-cells: from common clock binding; shall be set to 1.
- clocks: from common clock binding; list of parent clock
handles, shall be reference clock(s) connected to CLK_IN0
and CLK_IN1 pins.
- clock-names: shall be clk_in0 and/or clk_in1. Use clk_in0
in case of crystal oscillator or differential signal input
configuration. Use clk_in0 and clk_in1 in case of independent
single-ended LVCMOS inputs configuration.
Example:
clocks {
clk54: clk54 {
#clock-cells = <0>;
compatible = "fixed-clock";
clock-frequency = <54000000>;
};
};
...
i2c0: i2c-master@0d090000 {
...
cdce706: clock-synth@69 {
compatible = "ti,cdce706";
#clock-cells = <1>;
reg = <0x69>;
clocks = <&clk54>;
clock-names = "clk_in0";
};
};
