talos-obmc-linux/drivers/input/keyboard/max7359_keypad.c, branch v4.2

Input: max7359_keypad - switch to using matrix_keypad_build_keymap()

2015-05-15T22:58:40+00:00

max7359_build_keycode() does the same thing as matrix_keypad_build_keymap(), but the latter can also handle DT bindings. Tested on beagleboard-xm. Signed-off-by: Evgeniy A. Dushistov Signed-off-by: Dmitry Torokhov

Input: max7359_keypad - do not set MAX7359_CFG_INTERRUPT flag

2015-05-15T22:58:39+00:00

In datasheet of max7359 there is the following description of this flag: 0 - INT cleared when FIFO empty, 1 - INT cleared after host read. In this mode, I2C should read FIFO until interrupt condition removed, or further INT may be lost. So, if we set this flag, we have to read FIFO until it becomes empty. But in interrupt we read FIFO just once. This lead to "keyboard" hang until reboot, if we press several keys, because of interrupt handler read just one "press" from FIFO and clear interrupt.

Input: max7359 - introduce the use of managed interfaces

2014-07-20T20:17:00+00:00

This patch introduces the use of managed interfaces like devm_kzalloc, devm_input_allocate_device, devm_request_threaded_irq etc. and does away with the calls to free the allocated memory. The remove function is no longer required and is completely done away with. Also, the labels in the probe function are removed.

Input: use dev_get_platdata()

2013-12-06T10:06:29+00:00

Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability. Signed-off-by: Jingoo Han Acked-by: Fugang Duan Signed-off-by: Dmitry Torokhov

Input: max7359 - add CONFIG_PM_SLEEP to suspend/resume

2013-08-13T05:32:14+00:00

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the build warnings when CONFIG_PM_SLEEP is not selected. This is because sleep PM callbacks defined by SET_SYSTEM_SLEEP_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled. drivers/input/keyboard/max7359_keypad.c:275:12: warning: 'max7359_suspend' defined but not used [-Wunused-function] drivers/input/keyboard/max7359_keypad.c:287:12: warning: 'max7359_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han Signed-off-by: Dmitry Torokhov

Input: remove use of __devexit

2012-11-24T08:05:38+00:00

CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton Acked-by: Mark Brown Signed-off-by: Dmitry Torokhov

Input: convert I2C drivers to use module_i2c_driver()

2012-03-17T06:06:19+00:00

This patch converts the drivers in drivers/input/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler. Signed-off-by: Axel Lin Signed-off-by: Dmitry Torokhov

Input: max7359 - convert to dev_pm_ops

2011-02-21T09:02:30+00:00

There is a general move to convert drivers to use dev_pm_ops rather than bus specific ops to facilitate core work. Do this conversion for max7359. Signed-off-by: Mark Brown Signed-off-by: Dmitry Torokhov
