regulator: core: Add set/get_current_limit helpers for regmap users

2019-03-03T23:45:27Z

By setting curr_table, n_current_limits, csel_reg and csel_mask, the regmap users can use regulator_set_current_limit_regmap and regulator_get_current_limit_regmap for set/get_current_limit callbacks. Signed-off-by: Axel Lin Signed-off-by: Mark Brown

regulator: add regulator_desc_list_voltage_linear_range

2019-02-14T15:12:26Z

Add regulator_desc_list_voltage_linear_range which can be used by drivers for getting the voltages before regulator is registered. This may be useful for drivers which need to fetch the voltage selectors at device-tree parsing callback.

Merge tag 'bd71847-support' into regulator-4.20

2018-09-28T14:07:30Z

regulator/mfd: Support for the ROHM BD71847 This adds support for the BD71847 which touches both MFD and regulator. There's a few other bits and pieces included as some dependency patches had already been applied so would've required rebasing.

regulator: Support regulators where voltage ranges are selectable

2018-09-28T13:57:03Z

For example ROHM BD71837 and ROHM BD71847 Power management ICs have regulators which provide multiple linear ranges. Ranges can be selected by individual non contagious bit in vsel register. Add regmap helper functions for selecting ranges. Signed-off-by: Matti Vaittinen Signed-off-by: Mark Brown

regulator: regmap helpers - support overlapping linear ranges

Don't give up voltage mapping if first range with suitable min/max uV does not provide the wanted voltage. Signed-off-by: Matti Vaittinen Signed-off-by: Mark Brown

regulator: helpers: Add regmap set_pull_down helper

Add a helper function regulator_set_pull_down_regmap to allow regmap based regulators to easily enable pull down. Signed-off-by: Charles Keepax Signed-off-by: Mark Brown

regulator: helpers: Add regmap set_soft_start helper

regulators: helpers: Fix handling of bypass_val_on in get_bypass_regmap

2016-11-10T17:28:32Z

The handling of bypass_val_on that was added in regulator_get_bypass_regmap is done unconditionally however several drivers don't define a value for bypass_val_on. This results in those drivers reporting bypass being enabled when it is not. In regulator_set_bypass_regmap we use bypass_mask if bypass_val_on is zero. This patch adds similar handling in regulator_get_bypass_regmap.

regulator: helpers: Ensure bypass register field matches ON value

2016-04-22T10:49:03Z

When checking bypass state for a regulator, we check to see if any bits in the bypass mask are set. For most cases this is fine because there is typically, only a single bit used to determine if the regulator is in bypass. However, for some regulators, such as LDO6 on AS3722, the bypass state is indicate by a value rather than a single bit. Therefore, when checking the bypass state, check that the bypass field matches the ON value. Signed-off-by: Jon Hunter Signed-off-by: Mark Brown

regulator: helper: Add helper to configure active-discharge using regmap

2016-03-02T14:13:05Z

Add helper function to set the state of active-discharge of regulator using regmap. The HW regulator driver can directly use this by providing the necessary information in the regulator descriptor. Signed-off-by: Laxman Dewangan Signed-off-by: Mark Brown
