minmax: don't use max() in situations that want a C constant expression

2024-07-29T03:23:27Z

We only had a couple of array[] declarations, and changing them to just use 'MAX()' instead of 'max()' fixes the issue. This will allow us to simplify our min/max macros enormously, since they can now unconditionally use temporary variables to avoid using the argument values multiple times.

Pull input updates from Dmitry Torokhov: - streamlined logic in input core for handling normal input handlers vs input filters - updates to input drivers to allocate memory with sizeof(*pointer) instead of sizeof(type) - change to ads7846 touchscreen driver to use hsync GPIO instead of requiring platform data with special method (which is not compatible with boards using device tree) - update to adc-joystick driver to handle inverted axes - cleanups in various drivers switching them to use the new "guard" and "__free()" facilities - changes to several drivers (adxl34x, atmel_mxt_ts, ati-remote2, omap-keypad, yealink) to stop creating driver-specific device attributes manually and use driver core facilities for this - update to Cypress PS/2 protocol driver to properly handle errors from the PS/2 transport as well as other cleanups - update to edt-ft5x06 driver to support ft5426 variant - update to ektf2127 driver to support ektf2232 variant - update to exc3000 driver to support EXC81W32 variant - update to imagis driver to support IST3038 variant - other assorted driver cleanups. * tag 'input-for-v6.11-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (71 commits) Input: yealink - simplify locking in sysfs attribute handling Input: yealink - use driver core to instantiate device attributes Input: ati-remote2 - use driver core to instantiate device attributes Input: omap-keypad - use driver core to instantiate device attributes Input: atmel_mxt_ts - use driver core to instantiate device attributes Input: exc3000 - add EXC81W32 support dt-bindings: input: touchscreen: exc3000: add EXC81W32 Input: twl4030-pwrbutton - fix kernel-doc warning Input: himax_hx83112b - add support for HX83100A Input: himax_hx83112b - add himax_chip struct for multi-chip support Input: himax_hx83112b - implement MCU register reading Input: himax_hx83112b - use more descriptive register defines dt-bindings: input: touchscreen: himax,hx83112b: add HX83100A Input: do not check number of events in input_pass_values() Input: preallocate memory to hold event values Input: rearrange input_alloc_device() to prepare for preallocating of vals Input: simplify event handling logic Input: make events() method return number of events processed Input: make sure input handlers define only one processing method Input: evdev - remove ->event() method ...

Input: atmel_mxt_ts - use driver core to instantiate device attributes

2024-07-13T00:15:08Z

Instead of manually creating driver-specific device attributes, set struct driver->dev_groups pointer to have the driver core do it. Reviewed-by: Greg Kroah-Hartman Link: https://lore.kernel.org/r/Zo9kSFeGOZB9b3rq@google.com Signed-off-by: Dmitry Torokhov

Input: himax_hx83112b - add support for HX83100A

2024-07-08T23:22:50Z

The HX83100A is a bit of an outlier in the Himax HX831xxx series of touch controllers as it requires reading touch events through the AHB interface of the MCU rather than providing a dedicated FIFO address like the other chips do. This patch implements the specific read function and introduces the HX83100A chip with an appropriate i2c ID and DT compatible string. The HX83100A doesn't have a straightforward way to do chip identification, which is why it is not implemented in this patch.

Implement reading from the MCU in a more universal fashion. This allows properly handling reads of more than 4 bytes using the AHB FIFO implemented in the chip. Signed-off-by: Felix Kaechele Link: https://lore.kernel.org/r/20240620145019.156187-4-felix@kaechele.ca Signed-off-by: Dmitry Torokhov

Input: himax_hx83112b - use more descriptive register defines

2024-07-08T23:22:50Z

Himax uses an AHB-style bus to communicate with different parts of the display driver and touch controller system. Use more descriptive names for the register and address defines. The names were taken from a driver submission for the similar HX83102J chip.

Input: imagis - add supports for Imagis IST3038

2024-07-08T23:22:48Z

Imagis IST3038 is another variant of Imagis IST3038 IC, which has a different register interface from IST3038C (possibly firmware defined). Unlike IST3038C/IST3032C, IST3038 has different registers for commands, which means IST3038 doesn't use protocol B. Similar to IST3032C and maybe the other variants, IST3038 has touch keys support, which provides KEY_APPSELECT and KEY_BACK. Add support for IST3038 with touch keys.
