| * Freescale i.MX7ULP IOMUX Controller |
| |
| Please refer to fsl,imx-pinctrl.txt in this directory for common binding part |
| and usage. |
| |
| Required properties: |
| - compatible: "fsl,imx7ulp-iomuxc-0" or "fsl,imx7ulp-iomuxc-1" |
| - fsl,pins: two integers array, represents a group of pins mux and config |
| setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a |
| pin working on a specific function, CONFIG is the pad setting value like |
| pull-up for this pin. Please refer to imx7ulp datasheet for the valid pad |
| config settings. |
| |
| NOTE: i.MX7ULP PIN_FUNC_ID consists of 4 integers as it shares one mux and |
| config register as follows: |
| <mux_conf_reg input_reg mux_mode input_val> |
| |
| CONFIG bits definition: |
| PAD_CTL_OBE (1 << 17) |
| PAD_CTL_IBE (1 << 16) |
| PAD_CTL_LK (1 << 15) |
| PAD_CTL_DSE_HIGH (1 << 6) |
| PAD_CTL_DSE_STD (0 << 6) |
| PAD_CTL_ODE_OPEN_DRAIN (1 << 5) |
| PAD_CTL_ODE_PUSH_PULL (0 << 5) |
| PAD_CTL_SRE_SLOW (1 << 2) |
| PAD_CTL_SRE_STD (0 << 2) |
| PAD_CTL_PE_PULL (1 << 1) |
| PAD_CTL_PS_UP (1 << 0) |
| PAD_CTL_PS_DOWN (0 << 0) |
| |
| Refer to imx7ulp-pinfunc.h in device tree source folder for all available |
| imx7ulp PIN_FUNC_ID. |
