2024-07-15Input: qt1050 - use device_for_each_child_node_scoped()Javier Carrasco
Switch to the _scoped() version introduced in commit 365130fd47af ("device property: Introduce device_for_each_child_node_scoped()") to remove the need for manual calling of fwnode_handle_put() in the paths where the code exits the loop early. In this case the err label was no longer necessary and EINVAL is returned directly.

2023-12-12Input: qt1050 - 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.

2023-05-17Input: Switch i2c drivers back to use .probe()Uwe Kleine-König
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.

2022-12-07Input: qt1050 - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()Jonathan Cameron
SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings.

2019-05-07Input: qt1050 - add Microchip AT42QT1050 supportMarco Felsch
Add initial support for the AT42QT1050 (QT1050) device. The device supports up to five input keys, dependent on the mode. Since it adds only the initial support, the "1 to 4 keys plus Guard Channel" mode isn't supported.
