Input: sx8654 - do not override interrupt trigger

2019-02-05T07:32:42+00:00

We should rely on the interrupt trigger (level vs edge) set up by the
firmware or board code instead of forcing what we consider appropriate.

Input: sx8654 - convert #defined flags to BIT(x)

2019-02-05T07:25:54+00:00

Some of the #defined register values are one-bit flags. Convert them to
use the BIT(x) macro instead of 1 byte hexadecimal values. This improves
readability and clarifies the intent.

Input: sx8654 - use common of_touchscreen functions

2019-01-29T00:30:53+00:00

of_touchscreen.c provides a common interface for a axis inversion and
swapping of touchscreens. Therefore use it in the sx8654 driver.

Input: sx8654 - add sx8650 support

2019-01-29T00:30:43+00:00

The sx8654 and sx8650 are quite similar, therefore add support for the
sx8650 within the sx8654 driver.

Input: sx8654 - add sx8655 and sx8656 to compatibles

2019-01-29T00:27:28+00:00

As the sx865[456] share the same datasheet and differ only in the
presence of a "capacitive proximity detection circuit" and a "haptics
motor driver for LRA/ERM" add them to the compatbiles. As the driver
doesn't implement these features it should be no problem.

Input: sx8654 - add reset-gpio support

2019-01-29T00:27:26+00:00

The sx8654 features a NRST input which may be connected to a GPIO.
Therefore add support for hard-resetting the sx8654 via this NRST.

If the reset-gpio property is provided the sx8654 is resetted via NRST
instead of the soft-reset via I2C.

There is no call to i2c_get_clientdata(), platform_get_drvdata(),
or dev_get_drvdata() in any of the drivers in this patch.

"irqsrc" needs to be signed for the error handling to work.
