Add several enhancements to the Goodix touchscreen driver. The new functionality is only available for devices that declare named gpio pins for interrupt and reset in their ACPI/DT configuration.
Thanks, Irina 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, 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 Irina Tirdea (9): 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 Input: goodix - sort includes using inverse Xmas tree order .../bindings/input/touchscreen/goodix.txt | 11 + drivers/input/touchscreen/goodix.c | 766 +++++++++++++++++++-- 2 files changed, 732 insertions(+), 45 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
