Input: mpr121 - drop redundant wakeup handling

2026-03-11T00:05:50+00:00

The driver currently calls device_init_wakeup() and manually toggles IRQ wake in suspend and resume paths. This is unnecessary since the I2C core already handles wakeup configuration when the device is described in Device Tree with the "wakeup-source" property.

Input: mpr121 - use devm_regulator_get_enable_read_voltage()

2024-11-20T05:37:41+00:00

We can reduce boilerplate code by using devm_regulator_get_enable_read_voltage(). Reviewed-by: Jonathan Cameron Signed-off-by: David Lechner Link: https://lore.kernel.org/r/20241119-input-mpr121-regulator-get-enable-read-voltage-v3-1-1d8ee5c22f6c@baylibre.com Signed-off-by: Dmitry Torokhov

Input: drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-13T22:43:19+00:00

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

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.

Input: mpr121-touchkey - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2022-12-07T21:27:05+00:00

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. Signed-off-by: Jonathan Cameron Link: https://lore.kernel.org/r/20221204180841.2211588-9-jic23@kernel.org Signed-off-by: Dmitry Torokhov

Input: mpr121_touchkey - Convert to i2c's .probe_new()

2022-12-02T22:53:41+00:00

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221118224540.619276-201-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

Input: mpr121 - make use of the helper function devm_add_action_or_reset()

2021-09-23T04:56:50+00:00

The helper function devm_add_action_or_reset() will internally call devm_add_action(), and if devm_add_action() fails then it will execute the action mentioned and return the error code. So use devm_add_action_or_reset() instead of devm_add_action() to simplify the error handling, reduce the code.

Input: mpr121 - add polling mode

2019-10-16T00:43:54+00:00

In case the interrupt line is not available, polling can be used to read out the state of the keys. Period of the polling needs to be configured by the poll-interval DT property. Signed-off-by: Michal Vokáč Reviewed-by: Rob Herring Signed-off-by: Dmitry Torokhov

Use use device_property_count_u32() directly, that makes code neater. Signed-off-by: Andy Shevchenko Signed-off-by: Dmitry Torokhov
