* regulator: tps6105x: add optional devicetree supportSven Van Asbroeck2019-11-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Tell the regulator framework to retrieve regulator init data from the 'regulator' subnode, or from the parent mfd device's platform data. Example: i2c0 { tps61052@33 { compatible = "ti,tps61052"; reg = <0x33>; regulator { regulator-min-microvolt = <5000000>; regulator-max-microvolt = <5000000>; regulator-always-on; }; }; }; Tree: next-20191118 Signed-off-by: Sven Van Asbroeck <TheSven73@gmail.com> Link: https://lore.kernel.org/r/20191119154611.29625-3-TheSven73@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>
* tps6105x: add optional devicetree supportSven Van Asbroeck2019-11-201-3/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver currently requires platform data to specify the operational mode and regulator init data (in case of regulator mode). Optionally specify the operational mode by looking at the name of the devicetree child node. Example: put chip in regulator mode: i2c0 { tps61052@33 { compatible = "ti,tps61052"; reg = <0x33>; regulator { regulator-min-microvolt = <5000000>; regulator-max-microvolt = <5000000>; regulator-always-on; }; }; }; Tree: linux-next Signed-off-by: Sven Van Asbroeck <TheSven73@gmail.com> Link: https://lore.kernel.org/r/20191119154611.29625-2-TheSven73@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>

* regulator: ab8500: Remove AB8505 USB regulatorStephan Gerhold2019-11-071-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The USB regulator was removed for AB8500 in commit 41a06aa738ad ("regulator: ab8500: Remove USB regulator"). It was then added for AB8505 in commit 547f384f33db ("regulator: ab8500: add support for ab8505"). However, there was never an entry added for it in ab8505_regulator_match. This causes all regulators after it to be initialized with the wrong device tree data, eventually leading to an out-of-bounds array read. Given that it is not used anywhere in the kernel, it seems likely that similar arguments against supporting it exist for AB8505 (it is controlled by hardware). Therefore, simply remove it like for AB8500 instead of adding an entry in ab8505_regulator_match.

| * regulator: da9062: fix suspend_enable/disable preparationMarco Felsch2019-09-231-71/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the suspend reg_field maps to the pmic voltage selection bits and is used during suspend_enabe/disable() and during get_mode(). This seems to be wrong for both use cases. Use case one (suspend_enabe/disable): Those callbacks are used to mark a regulator device as enabled/disabled during suspend. Marking the regulator enabled during suspend is done by the LDOx_CONF/BUCKx_CONF bit within the LDOx_CONT/BUCKx_CONT registers. Setting this bit tells the DA9062 PMIC state machine to keep the regulator on in POWERDOWN mode and switch to suspend voltage. Use case two (get_mode): The get_mode callback is used to retrieve the active mode state. Since the regulator-setting-A is used for the active state and regulator-setting-B for the suspend state there is no need to check which regulator setting is active.

But it also caused unpaired clockdomain calls that won't allow idling the system. That's because clkdm_allow_idle_nolock() and clkdm_deny_idle_nolock() have usage count with clkdm->forcewake_count. Let's drop the unpaired sysc_clkdm_deny_idle() to fix idling of devices.
