Input: cros_ec_keyb - send 'scancodes' in addition to key events

2020-12-29T12:47:04+00:00

[ Upstream commit 80db2a087f425b63f0163bc95217abd01c637cb5 ] To let userspace know what 'scancodes' should be used in EVIOCGKEYCODE and EVIOCSKEYCODE ioctls, we should send EV_MSC/MSC_SCAN events in addition to EV_KEY/KEY_* events. The driver already declared MSC_SCAN capability, so it is only matter of actually sending the events.

Input: omap4-keypad - fix runtime PM error handling

2020-12-29T12:46:55+00:00

[ Upstream commit 59bbf83835f591b95c3bdd09d900f3584fa227af ] In omap4_keypad_probe, the patch fix several bugs. 1) pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to pm_runtime_put_noidle will result in reference leak. 2) In err_unmap, forget to disable runtime of device, pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced. 3) In err_pm_disable, it will call pm_runtime_put_sync twice not one time. To fix this we factor out code reading revision and disabling touchpad, and drop PM reference once we are done talking to the device.

Input: imx_keypad - make sure keyboard can always wake up system

2019-07-21T07:04:23+00:00

[ Upstream commit ce9a53eb3dbca89e7ad86673d94ab886e9bea704 ] There are several scenarios that keyboard can NOT wake up system from suspend, e.g., if a keyboard is depressed between system device suspend phase and device noirq suspend phase, the keyboard ISR will be called and both keyboard depress and release interrupts will be disabled, then keyboard will no longer be able to wake up system. Another scenario would be, if a keyboard is kept depressed, and then system goes into suspend, the expected behavior would be when keyboard is released, system will be waked up, but current implementation can NOT achieve that, because both depress and release interrupts are disabled in ISR, and the event check is still in progress. To fix these issues, need to make sure keyboard's depress or release interrupt is enabled after noirq device suspend phase, this patch moves the suspend/resume callback to noirq suspend/resume phase, and enable the corresponding interrupt according to current keyboard status.

Input: snvs_pwrkey - initialize necessary driver data before enabling IRQ

2019-05-08T05:20:52+00:00

commit bf2a7ca39fd3ab47ef71c621a7ee69d1813b1f97 upstream. SNVS IRQ is requested before necessary driver data initialized, if there is a pending IRQ during driver probe phase, kernel NULL pointer panic will occur in IRQ handler. To avoid such scenario, just initialize necessary driver data before enabling IRQ. This patch is inspired by NXP's internal kernel tree.
