regulator: ltc3589: Convert to use regulator_set_ramp_delay_regmap

2021-06-08T12:37:45Z

Use regulator_set_ramp_delay_regmap instead of open-coded LTC3589_LINEAR_REG() no longer call LTC3589_REG() now. Only LTC3589_LINEAR_REG() needs to set go_bit, thus remove go_bit parameter from LTC3589_REG() macro.

regulator: remove locking around regulator_notifier_call_chain()

2020-09-07T17:35:25Z

regulator_notifier_call_chain() doesn't need rdev lock and rdev's existence is assumed in the code anyway. Remove the locks from drivers.

regulator: ltc3589: Get rid of struct ltc3589_regulator

2019-04-26T09:38:20Z

After converting to use simplified DT parsing, the struct ltc3589_regulator only has a desc member. So let's remove struct ltc3589_regulator and use struct regulator_desc instead. Signed-off-by: Axel Lin Signed-off-by: Mark Brown

regulator: ltc3589: Fix notifier mutex lock warning

2019-03-13T15:11:55Z

The mutex for the regulator_dev must be controlled by the caller of the regulator_notifier_call_chain(), as described in the comment for that function. Failure to mutex lock and unlock surrounding the notifier call results in a kernel WARN_ON_ONCE() which will dump a backtrace for the regulator_notifier_call_chain() when that function call is first made. The mutex can be controlled using the regulator_lock/unlock() API.

regmap: split up regmap_config.use_single_rw

2018-09-07T12:03:55Z

Split regmap_config.use_single_rw into use_single_read and use_single_write. This change enables drivers of devices which only support bulk operations in one direction to use the regmap_bulk_*() functions for both directions and have their bulk operation split into single operations only when necessary. Update all struct regmap_config instances where use_single_rw==true to instead set both use_single_read and use_single_write. No attempt was made to evaluate whether it is possible to set only one of use_single_read or use_single_write. Signed-off-by: David Frey Signed-off-by: Mark Brown

regulator: ltc3589: constify i2c_device_id

2017-08-21T17:10:42Z

i2c_device_id are not supposed to change at runtime. All functions working with i2c_device_id provided by work with const i2c_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav Signed-off-by: Mark Brown

regulator: ltc3589: Add OF device ID table

2017-02-21T18:30:33Z

The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF. Signed-off-by: Javier Martinez Canillas Signed-off-by: Mark Brown
