Input: cap11xx - switch to for_each_child_of_node_scoped

2024-10-20T04:21:37Z

Use the scoped variant of the macro to simplify the code and error handling. This makes the error handling more robust by ensuring that the child node is always freed.

Input: cap11xx - stop using chip ID when configuring it

2024-06-07T19:32:31Z

struct cap11xx_hw_model is supposed to describe the chip capabilities, however later code changes introduced checks against chip ID. Introduce new capabilities in cap11xx_hw_model and use them when applying chip configuration, and remove the enum for chip ID. While at it, rename no_gain to has_gain to match the rest of the new capabilities.

Input: cap11xx - convert to use maple tree register cache

2023-12-13T05:39:09Z

The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache.

Input: cap11xx - cache hardware ID registers

2023-12-13T05:39:09Z

The cap11xx devices have three hardware identification registers which are currently marked as volatile, preventing caching of those registers. This is not ideal since the registers should never change at runtime, we should be able to cache the value after the first read. Stop marking the registers as volatile, we don't have register defaults specified in the driver so this will result in reading from the hardware on first use.

Input: cap11xx - add advanced sensitivity settings

2023-12-13T03:17:49Z

Add support for advanced sensitivity settings that allows more precise tunig of touch buttons. Input-treshold allows to set the sensitivity for each channel separately. Also add signal guard feature for CAP129x chips. Signed-off-by: Jiri Valek - 2N Link: https://lore.kernel.org/r/20231121155250.613242-3-jiriv@axis.com Signed-off-by: Dmitry Torokhov

Input: cap11xx - remove unnecessary IRQ parsing

2023-11-17T02:54:14Z

Separate IRQ parsing is not necessary, I2C core do the job. Signed-off-by: Jiri Valek - 2N Signed-off-by: Dmitry Torokhov

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

2023-05-17T16:59:11Z

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.

Input: cap11xx - add support for cap1203, cap1293 and cap1298

2023-02-04T00:52:01Z

Add basic support for more CAP1xxx sensors. All models from CAP1xxx family are register-compatible. Some advanced features are not used and disabled by default.

Input: cap11xx - Convert to i2c's .probe_new()

2022-12-02T22:53:41Z

.probe_new() doesn't get the i2c_device_id * parameter, so determine that explicitly in the probe function. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221118224540.619276-195-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

Input: cap11xx - add support for cap1206

2021-11-03T00:03:04Z

According to the datasheet "The CAP1206 is pin- and register-compatible with the CAP1106, with the exception of the GAIN[1:0] bits and ALT_POL bit"(57). So, this patch aims to disable them as they are no longer used. Signed-off-by: Jesse Taube Signed-off-by: Dmitry Torokhov
