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.

ltc3676_regulators is not modified and can be made const to allow the compiler to put it in read-only memory.

regulator: Convert i2c drivers to use .probe_new

2020-01-13T15:03:06Z

Use the new .probe_new for i2c drivers. These drivers do not use const struct i2c_device_id * argument, so convert them to utilise the simplified i2c driver registration. Signed-off-by: Axel Lin Link: https://lore.kernel.org/r/20200109155808.22003-1-axel.lin@ingics.com Signed-off-by: Mark Brown

regulator: ltc3676: Fix notifier mutex lock warning

2019-03-13T15:12:09Z

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.

Use case range for continuous range to make the code shorter. The .readable_reg and .writable_reg implementation are exactly the same, so use a common ltc3676_readable_writeable_reg function instead. Signed-off-by: Axel Lin Acked-by: Tim Harvey Signed-off-by: Mark Brown

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: ltc3676: Assure PGOOD mask is set before changing voltage

2018-05-01T21:00:20Z

Make sure the DVBxB bit 5, PGOOD mask, is set before changing voltage on the buck converters. If the PGOOD mask bit is not set, the PMIC may deassert the PGOOD signal during the voltage transition. On systems that use the PGOOD signal as a power OK indication for the board or SoC, which should be the case on correct designs, deasserting the PGOOD signal will lead to system reset or shutdown, which is not the expected behavior when changing PMIC buck converter voltage.
