mfd: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-07-04T16:08:02Z

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.

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

2023-06-15T08:19:37Z

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.

mfd: lp3943: Convert to i2c's .probe_new()

2022-12-07T13:27:21Z

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 Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20221118224540.619276-434-uwe@kleine-koenig.org

mfd: lp3943: Use devm_mfd_add_devices() for mfd_device registration

2016-04-19T06:55:23Z

Use devm_mfd_add_devices() for MFD devices registration and get rid of .remove callback to remove MFD child-devices. This is done by managed device framework. CC: Milo Kim Signed-off-by: Laxman Dewangan Acked-by: Milo Kim Signed-off-by: Lee Jones

mfd: Add LP3943 MFD driver

2014-01-21T08:27:59Z

LP3943 has 16 output pins which can be used as GPIO expander and PWM generator. * Regmap I2C interface for R/W LP3943 registers * Atomic operations for output pin assignment The driver should check whether requested pin is available or not. If the pin is already used, pin request returns as a failure. A driver data, 'pin_used' is checked when gpio_request() and pwm_request() are called. If the pin is available, then pin_used is set. And it is cleared when gpio_free() and pwm_free(). * Device tree support Compatible strings for GPIO and PWM driver. LP3943 platform data is PWM related, so parsing the device tree is implemented in the PWM driver. Signed-off-by: Milo Kim Signed-off-by: Lee Jones
