1 | Bindings for Texas Instruments CDCE706 programmable 3-PLL clock |
| 2 | synthesizer/multiplier/divider. | |
| 3 | ||
| 4 | Reference: http://www.ti.com/lit/ds/symlink/cdce706.pdf | |
| 5 | ||
| 6 | I2C device node required properties: | |
| 7 | - compatible: shall be "ti,cdce706". | |
| 8 | - reg: i2c device address, shall be in range [0x68...0x6b]. | |
| 9 | - #clock-cells: from common clock binding; shall be set to 1. | |
| 10 | - clocks: from common clock binding; list of parent clock | |
| 11 | handles, shall be reference clock(s) connected to CLK_IN0 | |
| 12 | and CLK_IN1 pins. | |
| 13 | - clock-names: shall be clk_in0 and/or clk_in1. Use clk_in0 | |
| 14 | in case of crystal oscillator or differential signal input | |
| 15 | configuration. Use clk_in0 and clk_in1 in case of independent | |
| 16 | single-ended LVCMOS inputs configuration. | |

| 18 | Example: | |

| 20 | clocks { | |
| 21 | clk54: clk54 { | |
| 22 | #clock-cells = <0>; | |
| 23 | compatible = "fixed-clock"; | |
| 24 | clock-frequency = <54000000>; | |
| 25 | }; | |
| 26 | }; | |

| 32 | #clock-cells = <1>; | |
