1 * Freescale i.MX6 SLL IOMUX Controller 2 3 Please refer to fsl,imx-pinctrl.txt in this directory for common binding part 4 and usage. 5 6 Required properties: 7 - compatible: "fsl,imx6sll-iomuxc" 8 - fsl,pins: each entry consists of 6 integers and represents the mux and config 9 setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val 10 input_val> are specified using a PIN_FUNC_ID macro, which can be found in 11 imx6sll-pinfunc.h under device tree source folder. The last integer CONFIG is 12 the pad setting value like pull-up on this pin. Please refer to i.MX6SLL 13 Reference Manual for detailed CONFIG settings. 14 15 CONFIG bits definition: 16 PAD_CTL_LVE (1 << 22) 17 PAD_CTL_HYS (1 << 16) 18 PAD_CTL_PUS_100K_DOWN (0 << 14) 19 PAD_CTL_PUS_47K_UP (1 << 14) 20 PAD_CTL_PUS_100K_UP (2 << 14) 21 PAD_CTL_PUS_22K_UP (3 << 14) 22 PAD_CTL_PUE (1 << 13) 23 PAD_CTL_PKE (1 << 12) 24 PAD_CTL_ODE (1 << 11) 25 PAD_CTL_SPEED_LOW (0 << 6) 26 PAD_CTL_SPEED_MED (1 << 6) 27 PAD_CTL_SPEED_HIGH (3 << 6) 28 PAD_CTL_DSE_DISABLE (0 << 3) 29 PAD_CTL_DSE_260ohm (1 << 3) 30 PAD_CTL_DSE_130ohm (2 << 3) 31 PAD_CTL_DSE_87ohm (3 << 3) 32 PAD_CTL_DSE_65ohm (4 << 3) 33 PAD_CTL_DSE_52ohm (5 << 3) 34 PAD_CTL_DSE_43ohm (6 << 3) 35 PAD_CTL_DSE_37ohm (7 << 3) 36 PAD_CTL_SRE_FAST (1 << 0) 37 PAD_CTL_SRE_SLOW (0 << 0) 38 39 Refer to imx6sll-pinfunc.h in device tree source folder for all available 40 imx6sll PIN_FUNC_ID.
