regulator: Add support for ramp delay

2019-03-11T06:53:19Z

Changing voltage and enabling regulator might require delays so the regulator stabilizes at expected level. Add support for "regulator-ramp-delay" binding which can introduce required time to both enabling the regulator and to changing the voltage.

power: regulator: Introduce regulator_set_enable_if_allowed api

2019-02-09T19:50:22Z

regulator_set_enable() api throws an error in the following three cases: - when requested to disable an always-on regulator - when set_enable() ops not provided by regulator driver - when enabling is actually failed.(Error returned by the regulator driver) Sometimes consumer drivers doesn't want to track the first two scenarios and just need to worry about the case where enabling is actually failed. But it is also a good practice to have an error value returned in the first two cases. So introduce an api regulator_set_enable_if_allowed() which ignores the first two error cases and returns an error as given by regulator driver. Consumer drivers can use this api need not worry about the first two error conditions. Signed-off-by: Lokesh Vutla Reviewed-by: Simon Glass

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

power: regulator: Introduce regulator_set_value_force function

2016-11-25T17:00:04Z

In case we want to force a particular value on a regulator irrespective of the min/max constraints for testing purposes one can call regulator_set_value_force function. Signed-off-by: Keerthy Reviewed-by: Simon Glass

power: regulator: Add ctrl_reg and volt_reg fields for pmic

2016-10-11T16:17:04Z

The ctrl reg contains bit fields to enable and disable regulators, and volt_reg has the bit fields to configure the voltage values. The registers are frequently accessed hence make them part of dm_regulator_uclass_platdata structure. Signed-off-by: Keerthy Reviewed-by: Tom Rini Reviewed-by: Simon Glass

power: regulator: Add support for gpio regulators

2016-10-11T16:17:04Z

Add support for gpio regulators. As of now this driver caters to gpio regulators with one gpio. Supports setting voltage values to gpio regulators and retrieving the values. Signed-off-by: Keerthy Reviewed-by: Simon Glass

dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()

2016-07-27T20:15:07Z

This new function is more convenient for callers, and handles pre-relocation situations automatically. Signed-off-by: Simon Glass

dm: regulator: add function device_get_supply_regulator()

2015-11-02T01:38:00Z

Some devices are supplied by configurable regulator's output. But there was no function for getting it. This commit adds function, that allows for getting the supply device by it's phandle. The returned regulator device can be used with regulator uclass's API. Signed-off-by: Przemyslaw Marczak Cc: Simon Glass Signed-off-by: Minkyu Kang

power: regulator: update comments for regulator-name
