2023-12-12Input: cap11xx - convert to use maple tree register cacheMark Brown
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.

2023-12-12Input: cap11xx - cache hardware ID registersMark Brown
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.

2023-12-12Input: cap11xx - add advanced sensitivity settingsJiri Valek - 2N
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.

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.

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 <mr.bossman075@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2019-02-09Input: cap11xx - switch to using set_brightness_blocking()Dmitry Torokhov
Updating LED state requires access to regmap and therefore we may sleep, so we could not do that directly form set_brightness() method. Historically we used private work to adjust the brightness, but with the introduction of set_brightness_blocking() we no longer need it. As a bonus, not having our own work item means we do not have use-after-free issue as we neglected to cancel outstanding work on driver unbind.
