power: regulator: Allow PWM regulator to be omitted from SPL.

2019-01-02T21:38:09Z

This patch allows to enable the PWM regulator driver independent for U-Boot and SPL. Signed-off-by: Christoph Muellner Reviewed-by: Philipp Tomsich

power: regulator: Return success on attempt to disable an always-on regulator

2018-12-27T12:48:31Z

commit 4f86a724e82c0 ("power: regulator: denied disable on always-on regulator") throws an error when requested to disable an always-on regulator. It is right that an always-on regulator should not be attempted to be disabled. But at the same time regulator framework should not return an error when such request is received. Instead it should just return success without attempting to disable the specified regulator. This is because the requesting driver will not have the idea if the regulator is always-on or not. The requesting driver will always try to enable/disable regulator as per the required flow. So it is upto regulator framework to not break such scenarios.

power: add FAN53555 family support

2018-12-10T09:04:45Z

This adds a driver for the FAN53555 family of regulators and wraps it in a PMIC implementation. While these devices support a 'normal' and 'suspend' mode (controlled via an external pin) to switch between two programmable voltages, this incarnation of the driver assumes that the device is always operating in 'normal' mode. Only setting/reading the programmed voltage is supported at this time and the following device functionality remains unsupported: - switching the selected voltage (via a GPIO) - disabling the voltage output via software-control This matches the functionality of the Linux driver. Tested on a RK3399-Q7 (with 'option 5' devices): setting voltages from the U-Boot shell and verifying output voltages on the board. Signed-off-by: Philipp Tomsich Tested-by: Klaus Goger

power: spl: add SPL_DM_REGULATOR_GPIO in Kconfig

2018-11-01T14:02:43Z

The Makefile already tests for SPL_DM_REGULATOR_GPIO, but Kconfig does not provide it. This adds SPL_DM_REGULATOR_GPIO to Kconfig. Signed-off-by: Lokesh Vutla

drivers: cosmetic: Convert SPDX license tags to Linux Kernel style

regulator: pbias: Add additional compatible flags

2018-09-12T01:38:37Z

The driver was developed with references for more than just dra7, but never included. At least for omap3, this appears to be functional. Signed-off-by: Adam Ford

drivers: regulator: fixed: add u-boot, off-on-delay-us

2018-08-20T00:38:39Z

Add u-boot,off-on-delay-us for fixed regulator. Depends on board design, the gpio regulator sometimes connects with a big capacitance. When need to off, then on the regulator, if there is no enough delay, the voltage does not drop to 0, so introduce this property to handle such case.

power: regulator: stpmu1: add power off delay

2018-07-19T20:31:36Z

This patch adds a delay when regulators are disabled. This delay is set to 5 ms to cover all use cases. The worst use case actually seen is during a SD card power cycle. Signed-off-by: Christophe Kerello Signed-off-by: Patrice Chotard

power: as3722: fix ldo_get/set_enable for ldo index bigger than 7

2018-05-10T23:34:20Z

Fix ldo_get_enable() and ldo_set_enable() functions for LDOs with an index > 7. Turns out there are actually two separate AS3722_LDO_CONTROL registers AS3722_LDO_CONTROL0 and AS3722_LDO_CONTROL1. Actually make use of both. While at it also actually use the enable parameter of the ldo_set_enable() function which now truly allows disabling as opposed to only enabling LDOs.
