Add several enhancements to the Goodix touchscreen driver.
I have added the esd_timeout DT property only for initialization to
get more feedback on this variant of the ESD patch.
Bastien, I have considered that both your boards (specified for rotated
screen quirk) have the reset pin declared first in the ACPI table.
Please let me know if that is correct.
I have also added an entry in sysfs to dump the config and a script that will
help create a new config for the device, if you want to look into the problem
with the Baytrail pinctrl warning.
Thanks,
Irina
Changes in v4:
- use dmi quirk to determine the order of irq and reset pins
- use actual config length depending on device
- add sysfs interface to dump config
- initialize esd timeout from ACPI/DT propery
Changes in v3:
- dropped the first 3 patches that got merged
- handle -EPROBE_DEFER and -ENOENT for gpio pins
- skip functionality depending on the gpio pins if the pins are not
properly initialized from ACPI/DT (reset, write config, power management,
ESD)
- dropped #ifdef CONFIG_PM_SLEEP and annotated with __maybe_unused instead
- use sysfs property to set ESD timeout instead of ACPI/DT property
- use request_firmware_nowait to read configuration firmware and use defaults
if firmware is not found
- use ACPI IDs to determine the order of the GPIO pins in the ACPI tables
(interrupt pin first or reset pin first)
Changes in v2:
- use request_firmware instead of ACPI/DT property for config
- dropped "input: goodix: add ACPI IDs for GT911 and GT9271" patch
- add ACPI DSDT excerpt in commit message where necessary
- add comments for suspend/resume sleep values
- dropped the checkpatch fixes that did not make sense
- added Bastien's ack to the first patch
