* tablet_mode: Introduce hall sensor specific handlingFurquan Shaikh2018-12-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change performs the following renaming: 1. CONFIG_TABLET_SWITCH -> CONFIG_HALL_SENSOR Indicates if a device has hall sensor 2. TABLET_MODE_GPIO_L -> HALL_SENSOR_GPIO_L Provides the interrupt line from hall sensor to EC. 3. tablet_mode_isr -> hall_sensor_isr Interrupt routine that gets control on hall sensor interrupt. 4. tablet_mode_init -> hall_sensor_init Init routine for initializing hall sensor interrupt. 5. tablet_switch_disable -> hall_sensor_disable Disable hall sensor interrupt and tablet mode sub-system. This is done to separate hall sensor interrupt from tablet mode handling. It is another step towards aligning tablet mode detection on EC with Chrome. Hall sensor interrupt occurs when the lid is in 360-degree flipped mode. If tablet mode is not already triggered by lid motion driver, then hall_sensor_isr will set tablet mode and take necessary actions to disable input peripherals.
