Input: atakbd - fix Atari CapsLock behaviour

2018-10-20T07:51:31+00:00

[ Upstream commit 52d2c7bf7c90217fbe875d2d76f310979c48eb83 ] The CapsLock key on Atari keyboards is not a toggle, it does send the normal make and break scancodes. Drop the CapsLock toggle handling code, which did cause the CapsLock key to merely act as a Shift key.

Input: atakbd - fix Atari keymap

2018-10-20T07:51:31+00:00

[ Upstream commit 9e62df51be993035c577371ffee5477697a56aad ] Fix errors in Atari keymap (mostly in keypad, help and undo keys). Patch provided on debian-68k ML by Andreas Schwab , keymap array size and unhandled scancode limit adjusted to 0x73 by me.

Input: qt1070 - add OF device ID table

2018-03-22T08:17:42+00:00

[ Upstream commit cf5cd9d4480a87da78768718cac194a71079b5cb ] The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF. The compatible strings don't have a vendor prefix because that's how it's used currently, and changing this will be a Device Tree ABI break.

Input: tca8418_keypad - remove double read of key event register

2018-03-18T10:18:53+00:00

commit 9dd46c02532a6bed6240101ecf4bbc407f8c6adf upstream. There is no need to tread the same register twice in a row. Fixes: ea4348c8462a ("Input: tca8418_keypad - hide gcc-4.9 -Wmaybe-un ...") Signed-off-by: Dmitry Torokhov Cc: Ben Hutchings Signed-off-by: Greg Kroah-Hartman

Input: matrix_keypad - fix race when disabling interrupts

2018-03-18T10:18:49+00:00

commit ea4f7bd2aca9f68470e9aac0fc9432fd180b1fe7 upstream. If matrix_keypad_stop() is executing and the keypad interrupt is triggered, disable_row_irqs() may be called by both matrix_keypad_interrupt() and matrix_keypad_stop() at the same time, causing interrupts to be disabled twice and the keypad being "stuck" after resuming. Take lock when setting keypad->stopped to ensure that ISR will not race with matrix_keypad_stop() disabling interrupts.

Input: tca8418_keypad - hide gcc-4.9 -Wmaybe-uninitialized warning

2018-02-25T10:05:54+00:00

commit ea4348c8462a20e8b1b6455a7145d2b86f8a49b6 upstream. Older versions of gcc warn about the tca8418_irq_handler function as they can't keep track of the variable assignment inside of the loop when using the -Wmaybe-unintialized flag: drivers/input/keyboard/tca8418_keypad.c: In function ‘tca8418_irq_handler’: drivers/input/keyboard/tca8418_keypad.c:172:9: error: ‘reg’ may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/input/keyboard/tca8418_keypad.c:165:5: note: ‘reg’ was declared here This is fixed in gcc-6, but it's possible to rearrange the code in a way that avoids the warning on older compilers as well.

Input: mpr121 - set missing event capability

2017-11-15T14:53:16+00:00

[ Upstream commit 9723ddc8fe0d76ce41fe0dc16afb241ec7d0a29d ] This driver reports misc scan input events on the sensor's status register changes. But the event capability for them was not set in the device initialization, so these events were ignored. This change adds the missing event capability.

Input: mpr121 - handle multiple bits change of status register

2017-11-15T14:53:15+00:00

[ Upstream commit 08fea55e37f58371bffc5336a59e55d1f155955a ] This driver reports input events on their interrupts which are triggered by the sensor's status register changes. But only single bit change is reported in the interrupt handler. So if there are multiple bits are changed at almost the same time, other press or release events are ignored. This fixes it by detecting all changed bits in the status register. Signed-off-by: Akinobu Mita Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

Input: gpio_keys - add support for GPIO descriptors

2017-04-12T10:41:19+00:00

[ Upstream commit 5feeca3c1e39c01f9ef5abc94dea94021ccf94fc ] GPIO descriptors are the preferred way over legacy GPIO numbers nowadays. Convert the driver to use GPIO descriptors internally but still allow passing legacy GPIO numbers from platform data to support existing platforms. Based on commits 633a21d80b4a2cd6 ("input: gpio_keys_polled: Add support for GPIO descriptors") and 1ae5ddb6f8837558 ("Input: gpio_keys_polled - request GPIO pin as input.").
