Input: ad7879 - use device core to create driver-specific device attributes

2023-09-06T21:23:47+00:00

Instead of creating driver-specific device attributes with devm_device_add_group() have device core do this by setting up dev_groups pointer in the driver structure.

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

2017-03-01T17:42:44+00:00

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 - use more devm interfaces

2017-02-23T17:21:26+00:00

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

Input: ad7879 - convert to use regmap

2017-02-23T17:21:26+00:00

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 - consolidate PM methods

2011-11-16T06:24:22+00:00

The PM methods are basically the same for SPI and I2C busses, so let's use the same dev_pm_ops for both of them. Acked-by: Michael Hennerich Signed-off-by: Dmitry Torokhov

Input: ad7879 - split bus logic out

2010-07-03T20:13:03+00:00

The ad7879 driver is using the old bus method of only supporting one at a time (I2C or SPI). So refactor it like the other input drivers that support multiple busses simultaneously. Signed-off-by: Mike Frysinger Signed-off-by: Michael Hennerich Signed-off-by: Dmitry Torokhov
