treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 149

2019-05-30T18:25:18Z

Based on 1 normalized pattern(s): licensed under the gpl 2 or later extracted by the scancode license scanner the SPDX license identifier GPL-2.0-or-later has been chosen to replace the boilerplate/reference in 82 file(s).

Input: ad7879 - return plain error code from ad7879_probe()

2017-03-01T17:42:44Z

With the switch to devm, there is no need for ad7879_probe() to return the touchscreen structure, we can use plain error code. This also fixes issue introduced with devm concersion, where we returned 0 on success (which worked OK since IS_ERR(0) would not trigger, but was not correct regardless).

Input: ad7879 - make sure we set up drvdata

2017-03-01T17:42:43Z

The conversion to devm accidentally removed setting up of I2C client data upon successful probe of the touchscreen. Let's move this setting into the core, so we do not forger about it again.

Input: ad7879 - use more devm interfaces

gpiochip_add now has a managed version, and we can remove sysfs attribute group via devm_add_action_or_reset (at least until we have devm version of sysfs_create_group). This allows us to get rid of ad7879_remove(). Reviewed-by: Michael Hennerich Tested-by: Michael Hennerich Signed-off-by: Dmitry Torokhov

Instead of rolling our own infrastructure to provide uniform access to I2C and SPI buses, let's switch to using regmap. Reviewed-by: Michael Hennerich Tested-by: Michael Hennerich Signed-off-by: Dmitry Torokhov

Input: ad7879 - add device tree support

2016-03-08T18:51:18Z

Add device tree support for the I2C and SPI variant of AD7879(-1). This allows to specify the touchscreen controller as a I2C client node or SPI slave device. Most of the options available in platform data are also available as device tree properties, the only exception being GPIO capabilities, which can not be activated through device tree currently.
