Input: tca6416-keypad - remove the driver

2025-08-12T21:42:28+00:00

This input driver predates proper GPIO driver for the chip and now can be replaced with the generic gpio-keys. Remove the driver. Link: https://lore.kernel.org/r/ajfsei3keh4jjasd4lshjicgqixew7bak3cmty3suoliskzgz4@vj3ijycfxy4i Signed-off-by: Dmitry Torokhov

Input: tca6416-keypad - remove unused struct tca6416_drv_data

Input: tca6416-keypad - remove an unused field in struct tca6416_keypad_chip

2024-05-06T22:41:28+00:00

In "struct tca6416_keypad_chip", the 'irqnum' field is unused. Remove it. Found with cppcheck, unusedStructMember. Signed-off-by: Christophe JAILLET Link: https://lore.kernel.org/r/926c0f40040671565dcc54d5146a8f9511fb6d46.1714541432.git.christophe.jaillet@wanadoo.fr Signed-off-by: Dmitry Torokhov

Input: tca6416-keypad - drop unused include

2023-12-14T05:26:13+00:00

The TCA6416 keypad driver is including the legacy GPIO header for no reason, it is not using any of its symbols. Drop the header. Signed-off-by: Linus Walleij Link: https://lore.kernel.org/r/20231129-descriptors-input-v1-2-9433162914a3@linaro.org Signed-off-by: Dmitry Torokhov

Input: tca6416-keypad - switch to using input core's polling features

2023-07-29T01:05:42+00:00

Instead of rolling custom polling implementation use input core facilities. Link: https://lore.kernel.org/r/20230724053024.352054-5-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov

Input: tca6416-keypad - convert to use devm_* api

2023-07-29T01:04:14+00:00

Use devm_* api to simplify code, this makes it unnecessary to explicitly release resources. Signed-off-by: Yangtao Li Link: https://lore.kernel.org/r/20230724053024.352054-4-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov

Input: tca6416-keypad - fix interrupt enable disbalance

2023-07-29T01:04:14+00:00

The driver has been switched to use IRQF_NO_AUTOEN, but in the error unwinding and remove paths calls to enable_irq() were left in place, which will lead to an incorrect enable counter value. Fixes: bcd9730a04a1 ("Input: move to use request_irq by IRQF_NO_AUTOEN flag") Link: https://lore.kernel.org/r/20230724053024.352054-3-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov

Input: tca6416-keypad - rely on I2C core to set up suspend/resume

2023-07-29T01:04:14+00:00

tca6416_keypad_suspend() and tca6416_keypad_resume() only configure device IRQ for wakeup. I2C core already does this by registering interrupt as a wakeup IRQ in case when device is marked as wakeup-enabled, so we can simply remove this code from the driver.

Input: tca6416-keypad - always expect proper IRQ number in i2c client

2023-07-29T01:04:14+00:00

Remove option having i2c client contain raw gpio number instead of proper IRQ number. There are no users of this facility in mainline and it will allow cleaning up the driver code with regard to wakeup handling, etc. Link: https://lore.kernel.org/r/20230724053024.352054-1-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov

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.
