Input: imagis - add support for imagis IST3038H

2025-02-25T02:11:06+00:00

Add support for imagis IST3038H, which seems mostly compatible with IST3038C except that it reports a different chip ID value. Tested on samsung,j5y17lte. Signed-off-by: Andras Sebok Link: https://lore.kernel.org/r/20250224090354.102903-2-sebokandris2009@gmail.com Signed-off-by: Dmitry Torokhov

Input: imagis - add supports for Imagis IST3038

2024-07-08T23:22:48+00:00

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.

Input: imagis - clarify the usage of protocol_b

2024-07-08T23:22:41+00:00

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. Note this could be confusing, unlike the model name implies. Adjust the usage of protocol_b to avoid confusion.

Input: imagis - add touch key support

2024-03-10T21:38:04+00:00

IST3032C (and possibly some other models) has touch keys. Add support for them to the imagis driver. Signed-off-by: Duje Mihanović Link: https://lore.kernel.org/r/20240306-b4-imagis-keys-v3-3-2c429afa8420@skole.hr Signed-off-by: Dmitry Torokhov

Input: imagis - use FIELD_GET where applicable

2024-03-10T21:38:04+00:00

Instead of manually extracting certain bits from registers with binary ANDs and shifts, the FIELD_GET macro can be used. With this in mind, the *_SHIFT macros can be dropped.

input/touchscreen: imagis: add support for IST3032C

2024-03-03T22:58:20+00:00

IST3032C is a touchscreen chip used for instance in the samsung,coreprimevelte smartphone, with which this was tested. Add the chip specific information to the driver.

input/touchscreen: imagis: Add support for Imagis IST3038B

2024-03-03T22:58:20+00:00

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.

Input: Switch i2c drivers back to use .probe()

2023-05-17T16:59:11+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.
