2022-11-23ACPI: make remove callback of ACPI driver voidDawei Li1-3/+1
For bus-based driver, device removal is implemented as: 1 device_remove()-> 2 bus->remove()-> 3 driver->remove() Driver core needs no inform from callee(bus driver) about the result of remove callback. In that case, commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned. Now we have the situation that both 1 & 2 of calling chain are void-returned, so it does not make much sense for 3(driver->remove) to return non-void to its caller. So the basic idea behind this change is making remove() callback of any bus-based driver to be void-returned. This change, for itself, is for device drivers based on acpi-bus.

2022-11-22Input: 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.

2022-11-22Input: 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.

Avoid resetting the module-wide i8042_platform_device pointer in i8042_probe() or i8042_remove(), so that the device can be properly destroyed by i8042_exit() on module unload.

2022-11-17Input: max8997 - convert to modern way to get a reference to a PWMUwe Kleine-König1-4/+3
pwm_request() isn't recommended to be used any more because it relies on global IDs for the PWM which comes with different difficulties. The new way to do things is to find the right PWM using a reference from the platform device. (This can be created either using a device-tree or a platform lookup table, see e.g. commit 5a4412d4a82f ("ARM: pxa: tavorevb: Use PWM lookup table") how to do this.) There are no in-tree users, so there are no other code locations that need adaption.

2022-11-17Input: 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.

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.
