1* Freescale IMX50 IOMUX Controller 2 3Please refer to fsl,imx-pinctrl.txt in this directory for common binding part 4and usage. 5 6Required properties: 7- compatible: "fsl,imx50-iomuxc" 8- fsl,pins: two integers array, represents a group of pins mux and config 9 setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a 10 pin working on a specific function, CONFIG is the pad setting value like 11 pull-up for this pin. Please refer to imx50 datasheet for the valid pad 12 config settings. 13 14CONFIG bits definition: 15PAD_CTL_HVE (1 << 13) 16PAD_CTL_HYS (1 << 8) 17PAD_CTL_PKE (1 << 7) 18PAD_CTL_PUE (1 << 6) 19PAD_CTL_PUS_100K_DOWN (0 << 4) 20PAD_CTL_PUS_47K_UP (1 << 4) 21PAD_CTL_PUS_100K_UP (2 << 4) 22PAD_CTL_PUS_22K_UP (3 << 4) 23PAD_CTL_ODE (1 << 3) 24PAD_CTL_DSE_LOW (0 << 1) 25PAD_CTL_DSE_MED (1 << 1) 26PAD_CTL_DSE_HIGH (2 << 1) 27PAD_CTL_DSE_MAX (3 << 1) 28PAD_CTL_SRE_FAST (1 << 0) 29PAD_CTL_SRE_SLOW (0 << 0) 30 31Refer to imx50-pinfunc.h in device tree source folder for all available 32imx50 PIN_FUNC_ID. 33
