2022-11-23Input: stmpe-ts - drop obsolete dependency on COMPILE_TESTJean Delvare1-1/+1
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.

2022-11-23Input: raydium_ts_i2c - use PM subsystem to manage wake irqRaul E Rangel1-6/+10
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.

2022-11-18Input: elants_i2c - properly handle the reset GPIO when power is offDouglas Anderson1-6/+3
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.

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.

Add support for the Hynitron cst3xx controller found on devices such as the Anbernic RG353P and RG353V (the Hynitron CST340). This driver was built from sources provided by Hynitron to Anbernic (possibly via Rockchip as an intermediary) and marked as GPLv2 in the code. This driver was written strictly for the cst3xx series, but in most places was left somewhat generic so support could be easily added to other devices in the future.

The thermal OF code has a new API allowing to migrate the OF initialization to a simpler approach. The ops are no longer device tree specific and are the generic ones provided by the core code. Convert the ops to the thermal_zone_device_ops format and use the new API to register the thermal zone with these generic ops.

2022-08-16i2c: Make remove callback return voidUwe Kleine-König9-27/+9
The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

2022-07-09Input: goodix - call acpi_device_fix_up_power() in some casesHans de Goede1-0/+5
On ACPI boards, when we cannot get the GPIOs to do a reset ourselves if necessary, call acpi_device_fix_up_power() to force the ACPI _PS0 method to run. On some devices without proper GPIO descriptions this will reset the touchscreen for us and this may be necessary for us to be able to communicate to the touchscreen at all. Specifically on an Aya Neo Next this change will cause the _PS0() ACPI function to call INIT() which does: Method (INIT, 0, Serialized) { TP_I = 0x00A50000 TP_R = 0x00A50000 Sleep (0x0A) TP_I = 0x00E50000 Sleep (One) TP_R = 0x00E50000 Sleep (0x06) TP_I = 0x00A50000 Sleep (0x3C) TP_I = 0x00041800 } On older kernels the ACPI core assumed a power-on was necessary by itself and would run _PS0 before our probe function runs, which can be seen from the GPIO pin ctrl registers in /sys/kernel/debug/gpio which match the above hex values with older kernels. With newer kernels before this change the GPIO pin ctrl registers do not match, indicating INIT() has not run and probing the touchscreen fails. This change makes Linux run _PS0() again fixing the touchscreen not working on the Aya Neo Next.

wm97xx_remove() returns zero unconditionally. To prepare changing the prototype for platform remove callbacks to return void, make it explicit that wm97xx_mfd_remove() always returns zero. The prototype for wm97xx_remove cannot be changed, as it's also used as a plain device remove callback.
