1* Freescale IMX6Q 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,imx6q-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 imx6q datasheet for the valid pad 12 config settings. 13 14CONFIG bits definition: 15PAD_CTL_HYS (1 << 16) 16PAD_CTL_PUS_100K_DOWN (0 << 14) 17PAD_CTL_PUS_47K_UP (1 << 14) 18PAD_CTL_PUS_100K_UP (2 << 14) 19PAD_CTL_PUS_22K_UP (3 << 14) 20PAD_CTL_PUE (1 << 13) 21PAD_CTL_PKE (1 << 12) 22PAD_CTL_ODE (1 << 11) 23PAD_CTL_SPEED_LOW (1 << 6) 24PAD_CTL_SPEED_MED (2 << 6) 25PAD_CTL_SPEED_HIGH (3 << 6) 26PAD_CTL_DSE_DISABLE (0 << 3) 27PAD_CTL_DSE_240ohm (1 << 3) 28PAD_CTL_DSE_120ohm (2 << 3) 29PAD_CTL_DSE_80ohm (3 << 3) 30PAD_CTL_DSE_60ohm (4 << 3) 31PAD_CTL_DSE_48ohm (5 << 3) 32PAD_CTL_DSE_40ohm (6 << 3) 33PAD_CTL_DSE_34ohm (7 << 3) 34PAD_CTL_SRE_FAST (1 << 0) 35PAD_CTL_SRE_SLOW (0 << 0) 36 37Refer to imx6q-pinfunc.h in device tree source folder for all available 38imx6q PIN_FUNC_ID.
