1 C6X PLL Clock Controllers 2 ------------------------- 3 4 This is a first-cut support for the SoC clock controllers. This is still 5 under development and will probably change as the common device tree 6 clock support is added to the kernel. 7 8 Required properties: 9 10 - compatible: "ti,c64x+pll" 11 May also have SoC-specific value to support SoC-specific initialization 12 in the driver. One of: 13 "ti,c6455-pll" 14 "ti,c6457-pll" 15 "ti,c6472-pll" 16 "ti,c6474-pll" 17 18 - reg: base address and size of register area 19 - clock-frequency: input clock frequency in hz 20 21 22 Optional properties: 23 24 - ti,c64x+pll-bypass-delay: CPU cycles to delay when entering bypass mode 25 26 - ti,c64x+pll-reset-delay: CPU cycles to delay after PLL reset 27 28 - ti,c64x+pll-lock-delay: CPU cycles to delay after PLL frequency change 29 30 Example: 31 32 clock-controller@29a0000 { 33 compatible = "ti,c6472-pll", "ti,c64x+pll"; 34 reg = <0x029a0000 0x200>; 35 clock-frequency = <25000000>; 36 37 ti,c64x+pll-bypass-delay = <200>; 38 ti,c64x+pll-reset-delay = <12000>; 39 ti,c64x+pll-lock-delay = <80000>; 40 };
