| mmi-factory-driver |
| |
| This is a mechanism to use the standard device tree to export the GPIOs |
| required in factory test environments. It is dependent upon environment |
| variable of /chosen/mmi,factory-cable being present. If the property |
| does not exist, the platform driver will not probe. |
| |
| Required properties: |
| - compatible: "mmi,factory-support-msm8960" |
| |
| - gpios: array of GPIOs and GPIOF flags to request, configure, and export by |
| the driver. The flags are standard GPIO flag bitmasks: |
| |
| GPIOF_DIR_OUT (0 << 0) |
| GPIOF_DIR_IN (1 << 0) |
| GPIOF_INIT_LOW (0 << 1) |
| GPIOF_INIT_HIGH (1 << 1) |
| GPIOF_OPEN_DRAIN (1 << 2) |
| GPIOF_OPEN_SOURCE (1 << 3) |
| |
| - gpio-names: matching label to apply to the above GPIO list. It must contain |
| same number of entries as the gpio array. |
| |
| Example: |
| |
| factory_support { |
| compatible = "mmi,factory-support-msm8960"; |
| |
| gpios = <&msmgpio 75 0x2>, /* GPIOF_DIR_OUT | GPIOF_INIT_HIGH */ |
| <&msmgpio 98 0x1>; /* GPIOF_DIR_IN */ |
| gpio-names = "factory_kill_disable", |
| "temp_sensor"; |
| }; |
