| | | | | | | | | | | | | | | | | | | | | When the screen brightness is changed, DP sends signal on AUX channel. This causes CCD mode to be disconnected.

* tablet_mode: Renaming for GMR sensorPhilip Chen2019-09-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GMR sensors can be used to (1) detect clamshell/tablet mode (2) detect lid open/closed But hall sensors can only do (2). Therefore the naming related to "hall sensor" for tablet mode application is incorrect. This patch performs the following renaming to better reflect the reality: config: CONFIG_HALL_SENSOR -> CONFIG_GMR_TABLET_MODE CONFIG_HALL_SENSOR_CUSTOM -> CONFIG_GMR_TABLET_MODE_CUSTOM CONFIG_DPTF_MOTION_LID_NO_HALL_SENSOR -> CONFIG_DPTF_MOTION_LID_NO_GMR_SENSOR GPIO: HALL_SENSOR_GPIO_L -> GMR_TABLET_MODE_GPIO_L functions: hall_sensor_disable() -> gmr_tablet_switch_disable() hall_sensor_isr() -> gmr_tablet_switch_isr() hall_sensor_int() -> gmr_tablet_switch_init() variable: hall_sensor_at_360 -> gmr_sensor_at_360 BUG=b:139378190 BRANCH=none TEST=make buildall Change-Id: I28393d056ddd128d8ffafc16a1f9fefee5455ccc Signed-off-by: Philip Chen <philipchen@google.com> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/1757275 Reviewed-by: Furquan Shaikh <furquan@chromium.org> Reviewed-by: Aseda Aboagye <aaboagye@chromium.org> Commit-Queue: Philip Chen <philipchen@chromium.org> Tested-by: Philip Chen <philipchen@chromium.org>
* tablet_mode: Introduce hall sensor specific handlingFurquan Shaikh2018-11-291-1/+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.
