mfd: rc5t583: Convert to use maple tree register cache

2024-02-23T14:58:05+00:00

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.

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

2023-06-15T08:19:37+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.

mfd: rc5t583: Convert to i2c's .probe_new()

2022-12-07T13:27:23+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 Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20221118224540.619276-452-uwe@kleine-koenig.org

mfd: rc5t583: Make it explicitly non-modular

2019-02-01T08:21:13+00:00

The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_RC5T583 drivers/mfd/Kconfig: bool "Ricoh RC5T583 Power Management system device" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

mfd: rc5t583: Improve a size determination

2018-05-16T08:21:48+00:00

Replace the specification of a data structure by a pointer dereference as the parameter for the operator "sizeof" to make the corresponding size determination a bit safer according to the Linux coding style convention.

mfd: rc5t583: Use devm_mfd_add_devices and devm_request_threaded_irq

2016-05-09T12:27:38+00:00

Use devm_mfd_add_devices() for adding MFD child devices and devm_request_threaded_irq() for IRQ registration. This reduces the need of remove callback for removing MFD child devices and unregistering IRQ. Signed-off-by: Laxman Dewangan Signed-off-by: Lee Jones

mfd: rc5t583: Set regmap config reg counts properly

2016-03-16T08:50:34+00:00

Regmap config max_register field should contain number of device last register, however num_reg_defaults_raw field should be set to register count instead (usually one register more than max_register). rc5t583 driver had both of these fields set to the same value, fix this by introducing separate defines for max register number and total count of registers.

mfd: Drop owner assignment from i2c_drivers

i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Lee Jones
