2024-06-03Input: silead - Always support 10 fingersHans de Goede
When support for Silead touchscreens was orginal added some touchscreens with older firmware versions only supported 5 fingers and this was made the default requiring the setting of a "silead,max-fingers=10" uint32 device-property for all touchscreen models which do support 10 fingers. There are very few models with the old 5 finger fw, so in practice the setting of the "silead,max-fingers=10" is boilerplate which needs to be copy and pasted to every touchscreen config. Reporting that 10 fingers are supported on devices which only support 5 fingers doesn't cause any problems for userspace in practice, since at max 4 finger gestures are supported anyways. Drop the max_fingers configuration and simply always assume 10 fingers.

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own.

2024-01-19Input: goodix - accept ACPI resources with gpio_count == 3 && gpio_int_idx == 0Hans de Goede
Some devices list 3 Gpio resources in the ACPI resource list for the touchscreen: 1. GpioInt resource pointing to the GPIO used for the interrupt 2. GpioIo resource pointing to the reset GPIO 3. GpioIo resource pointing to the GPIO used for the interrupt Note how the third extra GpioIo resource really is a duplicate of the GpioInt provided info. Ignore this extra GPIO, treating this setup the same as gpio_count == 2 && gpio_int_idx == 0 fixes the touchscreen not working on the Thunderbook Colossus W803 rugged tablet and likely also on the CyberBook_T116K.

2023-10-04Input: goodix - ensure int GPIO is in input for gpio_count == 1 && ↵Hans de Goede
gpio_int_idx == 0 case Add a special case for gpio_count == 1 && gpio_int_idx == 0 to goodix_add_acpi_gpio_mappings(). It seems that on newer x86/ACPI devices the reset and irq GPIOs are no longer listed as GPIO resources instead there is only 1 GpioInt resource and _PS0 does the whole reset sequence for us. This means that we must call acpi_device_fix_up_power() on these devices to ensure that the chip is reset before we try to use it. This part was already fixed in commit 3de93e6ed2df ("Input: goodix - call acpi_device_fix_up_power() in some cases") by adding a call to acpi_device_fix_up_power() to the generic "Unexpected ACPI resources" catch all. But it turns out that this case on some hw needs some more special handling. Specifically the firmware may bootup with the IRQ pin in output mode. The reset sequence from ACPI _PS0 (executed by acpi_device_fix_up_power()) should put the pin in input mode, but the GPIO subsystem has cached the direction at bootup, causing request_irq() to fail due to gpiochip_lock_as_irq() failure: [ 9.119864] Goodix-TS i2c-GDIX1002:00: Unexpected ACPI resources: gpio_count 1, gpio_int_idx 0 [ 9.317443] Goodix-TS i2c-GDIX1002:00: ID 911, version: 1060 [ 9.321902] input: Goodix Capacitive TouchScreen as /devices/pci0000:00/0000:00:17.0/i2c_designware.4/i2c-5/i2c-GDIX1002:00/input/input8 [ 9.327840] gpio gpiochip0: (INT3453:00): gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ [ 9.327856] gpio gpiochip0: (INT3453:00): unable to lock HW IRQ 26 for IRQ [ 9.327861] genirq: Failed to request resources for GDIX1002:00 (irq 131) on irqchip intel-gpio [ 9.327912] Goodix-TS i2c-GDIX1002:00: request IRQ failed: -5 Fix this by adding a special case for gpio_count == 1 && gpio_int_idx == 0 which adds an ACPI GPIO lookup table for the int GPIO even though we cannot use it for reset purposes (as there is no reset GPIO). Adding the lookup will make the gpiod_int = gpiod_get(..., GPIOD_IN) call succeed, which will explicitly set the direction to input fixing the issue. Note this re-uses the acpi_goodix_int_first_gpios[] lookup table, since there is only 1 GPIO in the ACPI resources the reset entry in that lookup table will amount to a no-op.

2023-09-23Input: wm97xx-core - convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
