Input: matrix_keypad - fix race when disabling interrupts

2018-03-21T03:49:50Z

[ Upstream commit ea4f7bd2aca9f68470e9aac0fc9432fd180b1fe7 ] 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: keyboard: drop owner assignment from platform_drivers

2014-10-20T14:20:39Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

Input: matrix_keypad - use request_any_context_irq()

2014-09-09T23:52:19Z

When trying to use the matrix-keypad driver with GPIO drivers that require nested irq handlers (e.g. I2C GPIO adapters like PCA9554), request_irq() fails because the GPIO driver requires a threaded interrupt handler. Use request_any_context_irq() to be able to use any GPIO driver as keypad driver. Signed-off-by: Lothar Waßmann Signed-off-by: Dmitry Torokhov

Input: delete non-required instances of include

2014-01-07T07:23:57Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Dmitry Torokhov

Input: matrix_keypad - remove redundant platform_set_drvdata()

2013-05-08T16:04:47Z

Commit 0998d06310 (device-core: Ensure drvdata = NULL when no driver is bound) removes the need to set driver data field to NULL. Signed-off-by: Sachin Kamat Acked-by: Marek Vasut Signed-off-by: Dmitry Torokhov

gpio: Make of_count_named_gpios() use new of_count_phandle_with_args()

2013-02-13T10:11:53Z

This patch replaces the horribly coded of_count_named_gpios() with a call to of_count_phandle_with_args() which is far more efficient. This also changes the return value of of_gpio_count() & of_gpio_named_count() from 'unsigned int' to 'int' so that it can return an error code. All the users of that function are fixed up to correctly handle a negative return value. v2: Split GPIO portion into a separate patch Tested-by: Andreas Larsson Signed-off-by: Grant Likely Cc: Linus Walleij Cc: Rob Herring

Input: matrix-keypad - add device tree support

2012-11-21T06:55:10Z

Also the driver was modifued to take advantage of recent improvements in matrix_keypad_build_keymap() implementation, which automatically allocates memory for keymap. The driver was tested on AM335x EVM. Signed-off-by: AnilKumar Ch Acked-by: Rob Herring Signed-off-by: Dmitry Torokhov
