Input: st1232 - do not reset the chip too early

2020-01-04T18:16:53+00:00

[ Upstream commit efd7bb08a762d4f6322054c6824bd942971ac563 ] We should not be putting the chip into reset while interrupts are enabled and ISR may be running. Fix this by installing a custom devm action and powering off the device/resetting GPIO line from there. This ensures proper ordering.

Input: st1232 - fix reporting multitouch coordinates

2019-10-21T17:15:03+00:00

For Sitronix st1633 multi-touch controller driver the coordinates reported for multiple fingers were wrong, as it was always taking LSB of coordinates from the first contact data.

Input: st1232 - handle common DT bindings

2019-02-17T05:39:42+00:00

This is required to specify generic touchscreen properties via DT. Signed-off-by: Matthias Fend Reviewed-by: Rob Herring Signed-off-by: Dmitry Torokhov

Input: st1232 - switch to gpiod API

2019-02-17T05:39:39+00:00

Use devm_gpiod_get_optional() and gpiod_set_value_cansleep() instead of the old API. The st1232_ts_power() now passes on the inverted "poweron" value to reflect the correct logical value. Signed-off-by: Martin Kepplinger Signed-off-by: Dmitry Torokhov

Input: st1232 - add Martin as module author

2019-01-28T19:24:48+00:00

This adds myself as an author of the st1232 driver module as Tony's email address doesn't seem to work anymore. Signed-off-by: Martin Kepplinger Signed-off-by: Dmitry Torokhov

Commit 1fa59bda21c7fa36 ("ARM: shmobile: Remove legacy board code for Armadillo-800 EVA"), removed the last user of st1232_pdata and the "st1232-ts" platform device. All remaining users use DT. Signed-off-by: Geert Uytterhoeven Signed-off-by: Dmitry Torokhov

Input: touchscreen - drop unnecessary calls to device_init_wakeup

2017-01-22T07:53:30+00:00

Calling device_init_wakeup in the remove function is unnecessary since the device is going away, and thus won't be able to cause any wakeups under any circumstances. Besides, the driver cleanup code already handles the necessary cleanup. Similarly, disabling wakeup in the probe error path is unnecessary, as is disabling wakeup in the probe function in the first place. Signed-off-by: Guenter Roeck Signed-off-by: Dmitry Torokhov
