1ST Microelectronics Nomadik SRC System Reset and Control 2 3This binding uses the common clock binding: 4Documentation/devicetree/bindings/clock/clock-bindings.txt 5 6The Nomadik SRC controller is responsible of controlling chrystals, 7PLLs and clock gates. 8 9Required properties for the SRC node: 10- compatible: must be "stericsson,nomadik-src" 11- reg: must contain the SRC register base and size 12 13Optional properties for the SRC node: 14- disable-sxtalo: if present this will disable the SXTALO 15 i.e. the driver output for the slow 32kHz chrystal, if the 16 board has its own circuitry for providing this oscillator 17- disable-mxtal: if present this will disable the MXTALO, 18 i.e. the driver output for the main (~19.2 MHz) chrystal, 19 if the board has its own circuitry for providing this 20 osciallator 21 22 23PLL nodes: these nodes represent the two PLLs on the system, 24which should both have the main chrystal, represented as a 25fixed frequency clock, as parent. 26 27Required properties for the two PLL nodes: 28- compatible: must be "st,nomadik-pll-clock" 29- clock-cells: must be 0 30- clock-id: must be 1 or 2 for PLL1 and PLL2 respectively 31- clocks: this clock will have main chrystal as parent 32 33 34HCLK nodes: these represent the clock gates on individual 35lines from the HCLK clock tree and the gate for individual 36lines from the PCLK clock tree. 37 38Requires properties for the HCLK nodes: 39- compatible: must be "st,nomadik-hclk-clock" 40- clock-cells: must be 0 41- clock-id: must be the clock ID from 0 to 63 according to 42 this table: 43 44 0: HCLKDMA0 45 1: HCLKSMC 46 2: HCLKSDRAM 47 3: HCLKDMA1 48 4: HCLKCLCD 49 5: PCLKIRDA 50 6: PCLKSSP 51 7: PCLKUART0 52 8: PCLKSDI 53 9: PCLKI2C0 54 10: PCLKI2C1 55 11: PCLKUART1 56 12: PCLMSP0 57 13: HCLKUSB 58 14: HCLKDIF 59 15: HCLKSAA 60 16: HCLKSVA 61 17: PCLKHSI 62 18: PCLKXTI 63 19: PCLKUART2 64 20: PCLKMSP1 65 21: PCLKMSP2 66 22: PCLKOWM 67 23: HCLKHPI 68 24: PCLKSKE 69 25: PCLKHSEM 70 26: HCLK3D 71 27: HCLKHASH 72 28: HCLKCRYP 73 29: PCLKMSHC 74 30: HCLKUSBM 75 31: HCLKRNG 76 (32, 33, 34, 35 RESERVED) 77 36: CLDCLK 78 37: IRDACLK 79 38: SSPICLK 80 39: UART0CLK 81 40: SDICLK 82 41: I2C0CLK 83 42: I2C1CLK 84 43: UART1CLK 85 44: MSPCLK0 86 45: USBCLK 87 46: DIFCLK 88 47: IPI2CCLK 89 48: IPBMCCLK 90 49: HSICLKRX 91 50: HSICLKTX 92 51: UART2CLK 93 52: MSPCLK1 94 53: MSPCLK2 95 54: OWMCLK 96 (55 RESERVED) 97 56: SKECLK 98 (57 RESERVED) 99 58: 3DCLK 100 59: PCLKMSP3 101 60: MSPCLK3 102 61: MSHCCLK 103 62: USBMCLK 104 63: RNGCCLK 105
