[PATCH v10 0/8] Goodix touchscreen enhancements

From: Irina Tirdea
Date: Wed Nov 18 2015 - 11:33:07 EST

This patchset depends on Dmitry's patch that fixes the
GPIO ACPI API[1], so devm_gpiod_get_optional can be properly
used in the code. Thanks for taking care of this, Dmitry!

Bastien and Aleksei, I have removed your Acked-by and Tested-by
tags from the patches I have changed.


[1] https://lkml.org/lkml/2015/11/11/465

Changes in v10:
- use devm_gpiod_get_optional and no longer ignore errors returned
by it
- use completion to signal other code paths in the driver that
the config firmware is loaded on the device
- dropped the patch that ordered the includes

Changes in v9:
- add GPIOLIB to driver dependencies
- add Tested-by tag from Bastien and Aleksei

Changes in v8:
- only allow new functionality for devices that declare named
gpios (using _DSD properties in ACPI or named DT properties)

Changes in v7:
- add dmi quirk to skip gpio pins setup and functionality that
depends on them for Onda v975w, WinBook TW100 and WinBook TW700.
- add support for named gpio pins
- rework the runtime pm patch to fix a couple of issues
- sort includes using inverse Xmas tree ordering

Changes in v6:
- skip runtime power manangent calls in open/close if the device
ACPI/DT configuration does not declare interrupt and reset gpio pins.
- reset the device before starting i2c communication
- add Bastien's ack to the first 2 patches

Changes in v5:
- add some more style cleanup (reorder includes, use error instead
of ret for return values)
- add runtime power management patch

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 properly

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,
- 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

Irina Tirdea (8):
Input: goodix - use actual config length for each device type
Input: goodix - reset device at init
Input: goodix - write configuration data to device
Input: goodix - add power management support
Input: goodix - use goodix_i2c_write_u8 instead of i2c_master_send
Input: goodix - add support for ESD
Input: goodix - add sysfs interface to dump config
Input: goodix - add runtime power management support
