Input: cyapa - remove redundant assignment to 'pwr_cmd'

2018-01-18T19:39:49Z

The variable pwr_cmd is being assigned to cyapa->suspend_power_mode twice, once during the declaration and once after taking an interruptible mutex lock. Remove the redundant first assignment since the value is never read and it is outside the mutex lock. Cleans up clang warning: drivers/input/mouse/cyapa.c:743:5: warning: Value stored to 'pwr_cmd' during its initialization is never read Signed-off-by: Colin Ian King Signed-off-by: Dmitry Torokhov

Input: mouse - use local variables consistently

2017-01-22T07:52:22Z

If a function declares a variable to access a structure element, use it consistently. Signed-off-by: Guenter Roeck Signed-off-by: Dmitry Torokhov

Input: cyapa - fix for losing events during device power transitions

2016-03-04T19:32:13Z

When changing the scan rate as part of runtime-resume process we may lose some of the events, because: 1) for gen3 trackpads, the driver must msleep() some time to ensure that the device is ready to accept next command; 2) for gen5 and later trackpads, the queue dumping function will simply ignore the events when waiting for the set power mode command response. The solution is to keep polling and report those valid events when the set power mode command is in progress. Signed-off-by: Dudley Du Tested-by: Jeremiah Mahler Signed-off-by: Dmitry Torokhov

Input: cyapa - introduce device tree binding

2015-07-30T18:33:59Z

Add device tree support for Cypress trackpad devices. Signed-off-by: Dudley Du Signed-off-by: Dmitry Torokhov

Input: cyapa - add regulator vcc support

2015-07-30T18:33:59Z

We need to power up the chip before we can initialize it. On systems that delegate task of powering up regulators to firmware we assume that we'll be simply given a dummy regulator. Signed-off-by: Dudley Du Signed-off-by: Dmitry Torokhov

Input: cyapa - add ACPI HID CYAP0002 for Gen6 devices

2015-07-24T00:34:06Z

Add CYTP0002 to the list of ACPI HIDs recognized by the driver. Signed-off-by: Dudley Du Signed-off-by: Dmitry Torokhov

Input: cyapa - fully support runtime suspend power management

2015-07-24T00:34:05Z

Fix the the runtime suspend power management not working issue when system starts up and before user touches the trackpad device. TEST=test on Chromebook. Signed-off-by: Dudley Du Signed-off-by: Dmitry Torokhov

Input: cyapa - add proximity support for gen5 and gen6 modules

2015-07-24T00:34:05Z

Gen5 and Gen6 trackpad devices are able to detect and report object proximity data/events, add this function support in the cyapa driver through the ABS_DISTANCE event. Signed-off-by: Dudley Du Signed-off-by: Dmitry Torokhov

Input: cyapa - add gen6 device module support

2015-07-24T00:34:04Z

Based on the cyapa core, add support for basic functionality of the gen6 trackpad devices. The driver can automatically determine what protocol (gen3, gen5, or gen6) should be used with the attached trackpad device. Signed-off-by: Dudley Du Signed-off-by: Dmitry Torokhov

Input: cyapa - rename 'gen5' to 'pip' for chared code

2015-07-24T00:34:03Z

Change 'gen5' to 'pip' for all macros, variables and functions that are shared between gen5 and gen6 modules to make naming more clear and readable. Also fix a few spelling errors. Signed-off-by: Dudley Du Signed-off-by: Dmitry Torokhov
