2021-06-02regulator: bd718x7: Fix the BUCK7 voltage setting on BD71837Matti Vaittinen
Changing the BD71837 voltages for other regulators except the first 4 BUCKs should be forbidden when the regulator is enabled. There may be out-of-spec voltage spikes if the voltage of these "non DVS" bucks is changed when enabled. This restriction was accidentally removed when the LDO voltage change was allowed for BD71847. (It was not noticed that the BD71837 BUCK7 used same voltage setting function as LDOs). Additionally this bug causes incorrect voltage monitoring register access. The voltage change function accidentally used for bd71837 BUCK7 is intended to only handle LDO voltage changes. A BD71847 LDO specific voltage monitoring disabling code gets executed on BD71837 and register offsets are wrongly calculated as regulator is assumed to be an LDO. Prevent the BD71837 BUCK7 voltage change when BUCK7 is enabled by using the correct voltage setting operation.

2021-05-24Merge series "Fix MAX77620 regulator driver regression" from Dmitry Osipenko ↵Mark Brown
<digetx@gmail.com>: Hi, The next-20210521 started to fail on Nexus 7 because of the change to regulator core that caused regression of the MAX77620 regulator driver. The regulator driver is now getting a deferred probe and turned out driver wasn't ready for this. The root of the problem is that OF node of the PMIC MFD sub-device is shared with the PINCTRL sub-device and we need to convey this information to the driver core, otherwise it will try to claim GPIO pin that is already claimed by PINCTRL and fail the probe.

2021-04-23regulator: core: Fix off_on_delay handlingVincent Whitchurch
The jiffies-based off_on_delay implementation has a couple of problems that cause it to sometimes not actually delay for the required time: (1) If, for example, the off_on_delay time is equivalent to one jiffy, and the ->last_off_jiffy is set just before a new jiffy starts, then _regulator_do_enable() does not wait at all since it checks using time_before(). (2) When jiffies overflows, the value of "remaining" becomes higher than "max_delay" and the code simply proceeds without waiting. Fix these problems by changing it to use ktime_t instead. [Note that since jiffies doesn't start at zero but at INITIAL_JIFFIES ("-5 minutes"), (2) above also led to the code not delaying if the first regulator_enable() is called when the ->last_off_jiffy is not initialised, such as for regulators with ->constraints->boot_on set. It's not clear to me if this was intended or not, but I've preserved this behaviour explicitly with the check for a non-zero ->last_off.] Signed-off-by: Vincent Whitchurch <vincent.whitchurch@axis.com> Link: https://lore.kernel.org/r/20210423114524.26414-1-vincent.whitchurch@axis.com Signed-off-by: Mark Brown <broonie@kernel.org>

2021-04-22regulator: core: Respect off_on_delay at startupVincent Whitchurch
We currently do not respect off_on_delay the first time we turn on a regulator. This is problematic since the regulator could have been turned off by the bootloader, or it could it have been turned off during the probe of the regulator driver (such as when regulator-fixed requests the enable GPIO), either of which could potentially have happened less than off_on_delay microseconds ago before the first time a client requests for the regulator to be turned on. We can't know exactly when the regulator was turned off, but initialise off_on_delay to the current time when registering the regulator, so that we guarantee that we respect the off_on_delay in all cases.

2021-04-02Merge series "Support ROHM BD71815 PMIC" from Matti Vaittinen ↵Mark Brown
<matti.vaittinen@fi.rohmeurope.com>: Patch series introducing support for ROHM BD71815 PMIC ROHM BD71815 is a power management IC used in some battery powered systems. It contains regulators, GPO(s), charger + coulomb counter, RTC and a clock gate. All regulators can be controlled via I2C. LDO4 can additionally be set to be enabled/disabled by a GPIO. LDO3 voltage could be selected from two voltages written into separate VSEL reisters using GPIO but this mode is not supported by driver. On top of that the PMIC has the typical HW state machine which is present also on many other ROHM PMICs. IC contains two GPOs - but one of the GPOs is marked as GND in data-sheet. Thus the driver by default only exposes one GPO. The second GPO can be enabled by special DT property. RTC is almost similar to what is on BD71828. For currently used features only the register address offset to RTC block differs. The charger driver is not included in this series. ROHM has a charger driver with some fuel-gauging logig written in but this is not included here. I am working on separating the logic from HW specific driver and supporting both BD71815 and BD71828 chargers in separate patch series. Changelog v5: Regulator: - Added regmap helper for regulator ramp-delay and taken it in use (patches 13, 14, 16 - they can be just dropped if ramp-delay helper is not a good idea. Patch 15 implements old-fashioned ramp-delay) GPIO: - styling changes to GPIO (Mostly suggested by Andy) - implemented init_valid_mask (but can't count on it yet) Changelog v4: - Sorted ROHM chip ID enum - Statcized DVS structures in regulator driver - Minor styling for regulator driver - rebased on v5.12-rc4 Changelog v3: - GPIO clean-up as suggested by Bartosz - MFD clean-up as suggested by Lee - clk-mode dt-binding handling in MFD driver corrected to reflect new property values. - Dropped already applied patches - Rebased on v5.12-rc2 Changelog v2: - Rebased on top of v5.11-rc3 - Added another "preliminary patch" which fixes HW-dvs voltage handling (patch 1) - split regulator patch to two. - changed dt-binding patch ordering. regulators: - staticized probe - removed some unnecessary defines - updated comments - split rohm-regulator patch adding SNVS and supporting simple linear mapping into two - one adding support for mapping, other adding SNVS. GPIO: - removed unnecessary headers - clarified dev/parent->dev usage - removed forgotten #define DEBUG dt-bindings: - changed patch order to meet ref-dependencies - added missing regulator nodes - changed string property for clk mode to tristated MFD: - header cleanups.

2021-04-02regulator: Add regmap helper for ramp-delay settingMatti Vaittinen
Quite a few regulator ICs do support setting ramp-delay by writing a value matching the delay to a ramp-delay register. Provide a simple helper for table-based delay setting.

2021-04-02regulator: helpers: Export helper voltage listingMatti Vaittinen
Some drivers need to translate voltage values to selectors prior regulator registration. Currently a regulator_desc based list_voltages helper is only exported for regulators using the linear_ranges. Export similar helper also for regulators using simple linear mapping.
