2024-07-08Input: himax_hx83112b - add support for HX83100AFelix Kaechele
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.

2024-07-08Input: imagis - add supports for Imagis IST3038Raymond Hackley
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.

2024-07-08Input: imagis - clarify the usage of protocol_bRaymond Hackley
protocol_b is a property, which tells Imagis panel to use a different format for coordinates. IST30XXC series is known for using protocol B, while the other series aren't.

2024-06-09Input: touchscreen - use sizeof(*pointer) instead of sizeof(type)Erick Archer
It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter). The refactoring is mostly trivial except for "usbtouchscreen.c" file. Here, in the "mtouch_alloc" and "nexio_alloc" functions, it is necessary to use a variable with a predefined type instead of the "usbtouch->priv" variable (void * type). This way, the "sizeof" operator can now know the correct size. Moreover, we need to set the "usbtouch->priv" pointer after the memory allocation since now the "kmalloc" return value is not assigned directly. This patch has no effect on runtime behavior.

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.

2024-03-03input/touchscreen: imagis: Add support for Imagis IST3038BMarkuss Broks
Imagis IST3038B is another variant of Imagis IST3038 IC, which has a different register interface from IST3038C (possibly firmware defined). This should also work for IST3044B (though untested), however other variants using this interface/protocol(IST3026, IST3032, IST3026B, IST3032B) have a different format for coordinates, and they'd need additional effort to be supported by this driver.

2024-01-30Input: goodix-berlin - add SPI support for Goodix Berlin Touchscreen ICNeil Armstrong
Add initial support for the new Goodix "Berlin" touchscreen ICs over the SPI interface. The driver doesn't use the regmap_spi code since the SPI messages needs to be prefixed, thus this custom regmap code. This initial driver is derived from the Goodix goodix_ts_berlin available at [1] and [2] and only supports the GT9916 IC present on the Qualcomm SM8550 MTP & QRD touch panel. The current implementation only supports BerlinD, aka GT9916.

2024-01-30Input: add core support for Goodix Berlin Touchscreen ICNeil Armstrong
Add initial support for the new Goodix "Berlin" touchscreen ICs. These touchscreen ICs support SPI, I2C and I3C interface, up to 10 finger touch, stylus and gestures events. This initial driver is derived from the Goodix goodix_ts_berlin available at [1] and [2] and only supports the GT9916 IC present on the Qualcomm SM8550 MTP & QRD touch panel. The current implementation only supports BerlinD, aka GT9916. Support for advanced features like: - Firmware & config update - Stylus events - Gestures events - Previous revisions support (BerlinA or BerlinB) is not included in current version. The current support will work with currently flashed firmware and config, and bail out if firmware or config aren't flashed yet.
