2022-11-22Input: stmpe-ts - drop obsolete dependency on COMPILE_TESTJean Delvare
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

2022-11-22Input: raydium_ts_i2c - use PM subsystem to manage wake irqRaul E Rangel
The raydium I2C touchscreen driver is currently manually managing the wake IRQ. This change removes the explicit enable_irq_wake / disable_irq_wake and instead relies on the PM subsystem. This is done by calling dev_pm_set_wake_irq. i2c_device_probe already calls dev_pm_set_wake_irq when using device tree, and i2c_device_remove also already calls dev_pm_clear_wake_irq. There could be some device tree systems that have incorrectly declared `wake` capabilities, so this change will set the wake irq if one is missing. This matches the previous behavior.

2022-11-17Input: elants_i2c - properly handle the reset GPIO when power is offDouglas Anderson
As can be seen in elants_i2c_power_off(), we want the reset GPIO asserted when power is off. The reset GPIO is active low so we need the reset line logic low when power is off to avoid leakage. We have a problem, though, at probe time. At probe time we haven't powered the regulators on yet but we have: devm_gpiod_get(&client->dev, "reset", GPIOD_OUT_LOW); While that _looks_ right, it turns out that it's not. The GPIOD_OUT_LOW doesn't mean to init the GPIO to low. It means init the GPIO to "not asserted". Since this is an active low GPIO that inits it to be high. Let's fix this to properly init the GPIO. Now after both probe and power off the state of the GPIO is consistent (it's "asserted" or level low). Once we fix this, we can see that at power on time we no longer to assert the reset GPIO as the first thing. The reset GPIO is _always_ asserted before powering on. Let's fix powering on to account for this.

2022-11-17Input: hynitron_cstxxx - initialize tmp to 0 to fix uninitialized variable issueChris Morgan
In the very unlikely event the cst3xx_i2c_write() fails inside of the cst3xx_bootloader_enter() function 5 times in a row, the uninitalized value of tmp will get compared to CST3XX_BOOTLDR_CHK_VAL. Initialize the value of tmp to 0 so that in this unlikely event we are comparing 0 instead of an uninitalized variable.

2022-11-14Input: msg2638 - add support for msg2138Vincent Knecht
msg2138 only supports 2 fingers presses, and needs different processing since second finger press is encoded as a delta position wrt. first one and the packet/touch_event structs are not the same as msg2638. Add support for it by implementing distinct structs and irq handler.

2022-11-07Input: add driver for Himax hx83112b touchscreen devicesJob Noorman
This patch adds support for Himax hx83112b touchscreen devices. As there are no publicly available data sheets for these devices, the implementation is based on the driver of the downstream Android kernel used in the Fairphone 3. This patch is a complete rewrite, though, and the code bears no resemblence to the original implementation. The driver has been tested on the aforementioned phone.

2022-11-03Input: goodix - try resetting the controller when no config is setHans de Goede
On ACPI systems (irq_pin_access_method == IRQ_PIN_ACCESS_ACPI_*) the driver does not reset the controller at probe time, because sometimes the system firmware loads a config and resetting might loose this config. On the Nanote UMPC-01 device OTOH the config is in flash of the controller, the controller needs a reset to load this; and the system firmware does not reset the controller on a cold boot. To fix the Nanote UMPC-01 touchscreen not working on a cold boot, try resetting the controller and then re-reading the config when encountering a config with 0 width/height/max_touch_num value and the controller has not already been reset by goodix_ts_probe(). This should be safe to do in general because normally we should never encounter a config with 0 width/height/max_touch_num. Doing this in general not only avoids the need for a DMI quirk, but also might help other systems.
