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.
Dmitry Osipenko (2):

The MAX77620 driver fails to re-probe on deferred probe because driver
core tries to claim resources that are already claimed by the PINCTRL
device. Use device_set_of_node_from_dev() helper which marks OF node as
reused, skipping erroneous execution of pinctrl_bind_pins() for the PMIC
device on the re-probe.

V3:
- Drop the SoC regulator constraints for
regulator-min-microamp
regulator-max-microamp
These will be applied on a per-board basis - Mark Brown
V2:
The first version of this patch set the current limit to 3 amps as was done
in downstream. Mark indicated a preference to set this on a per-system
basis instead of blitzing it, as in downstream.
Looking at what was upstream versus what was in my working tree I saw that
in fact the VBUS boost driver had been upstreamed minus accompanying DTS in
pm8150b.
So there's no need for a fixes as this driver doesn't appear to be in use.
A subsequent patchset will enable the VBUS boost for the two relevant
upstream platforms.
First thing though, is the driver + dts change.
- Use regulator_set_current_limit_regmap/regulator_get_current_limit_regmap
with a relevant current-to-bitmap lookup.
- Add a parallel DTS entry to the pm8150b
It looks like this was submitted upstream but not followed up on
I've add regulator-min-microamp/regulator-max-microamp to Wesley's
original work.
I've made sure to test that its possible to set the current to anything in
the range of 500 mA to 3 A and confirmed the output on a scope.
Once these two patches are in, I'll send out board enablement for the
sm8150-mtp and qrb5165-rb5.

Add hooks to regulator_get_current_limit_regmap() and
regulator_set_current_limit_regmap() with an accompanying map of amperages.
This lets us use the existing helper functions to map requested current
settings to register bit-map/indicies.
This change is required to elevate the default 2 Amps set by the bootloader
to 3 Amps or indeed to constrain the value lower as the system design may
dictate.
The valid range is 500 mA to 3 A in increments of 500 mA.

- Support for modular SCMI protocols and vendor specific extensions
- New SCMI IIO driver
- Per-cpu DVFS
The other driver changes are all from the platform maintainers
directly and reflect the drivers that don't fit into any other
subsystem as well as treewide changes for a particular platform.
SoCFPGA:
- Various cleanups contributed by Krzysztof Kozlowski
Mediatek:
- add MT8183 support to mutex driver
- MMSYS: use per SoC array to describe the possible routing
- add MMSYS support for MT8183 and MT8167

- add support for MT8192/MT6873
Tegra:
- Bug fixes to PMC and clock drivers
NXP/i.MX:
- Update SCU power domain driver to keep console domain power on.
- Add missing ADC1 power domain to SCU power domain driver.
- Update comments for single global power domain in SCU power domain
driver.

avoid issues with missing resources and unnecessary deferred probe
- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as
we now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and
dra7
- omap-prm driver needs to enable autoidle retention support for
omap4
- omap5 clocks are missing gpmc and ocmc clock registers

Here is the big set of staging and IIO driver updates for 5.13-rc1.
Lots of little churn in here, and some larger churn as well. Major
things are:
- removal of wimax drivers, no one has this hardware anymore for
this failed "experiment".
- removal of the Google gasket driver, turns out no one wanted
to maintain it or cares about it anymore, so they asked for it
to be removed.
- comedi finally moves out of the staging directory into
drivers/comedi/ This is one of the oldest kernel subsystems
around, being created in the 2.0 kernel days, and was one of
the first things added to drivers/staging/ when that was
created over 15 years ago. It should have been moved out of
staging a long time ago, it's well maintained and used by
loads of different devices in the real world every day. Nice
to see this finally happen.
- so many tiny coding style cleanups it's not funny. Perfect
storm of at least 2 different intern project application
deadlines combined to provide a huge number of new
contributions in this area from people learning how to do
kernel development. Great job to everyone involved here.
There's also the normal updates for IIO drivers with new IIO drivers and
updates all over that subsystem.
All of these have been in linux-next for a while with no reported
issues.

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.]

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.

Hi,
The Samsung PMIC drivers since long time are used only on devicetree
platforms (Samsung Exynos) and there are no users with board files.
Drop the support for board files entirely and depend on OF for matching.
This makes the code smaller and simpler.
Dependencies
============
The MFD pieces are rebased on my previous sec-core dirver changes:
mfd: sec: Simplify getting of_device_id match data
https://lore.kernel.org/linux-samsung-soc/20210420113929.278082-1-krzysztof.kozlowski@canonical.com/T/#t
Applying - can be independent
=============================
The last RTC and regulator patches can be picked up independently via
regulator and rtc trees. There are no board files currently, so the
code in these drivers is basically dead code and feature-bisection is
preserved.
Best regards,
Krzysztof
Krzysztof Kozlowski (9):
mfd: sec: Drop support for board files and require devicetree
mfd: sec: Remove unused cfg_pmic_irq in platform data
mfd: sec: Remove unused device_type in platform data
mfd: sec: Remove unused irq_base in platform data
mfd: sec: Enable wakeup from suspend via devicetree property
mfd: sec: Remove unused platform data members
rtc: s5m: Remove reference to parent's device pdata
regulator: s2mpa01: Drop initialization via platform data

The aim of this patch is to make the comment more readable and to make
it clear, that this is about a regulator, that is already enabled instead
of a regulator that may be switched on.

'for_each_available_child_of_node()' already performs an 'of_node_get()'
on child, so there is no need to perform another one before returning.
Otherwise, a double 'get' is performed and a resource may never be
released.

This patch fixes identification of DA913x parts by the DA9121 driver,
where a lack of clarity lead to implementation on the basis that variant
IDs were to be identical to the equivalent rated non-automotive parts.
There is a new emphasis on the DT identity to cope with overlap in these
ID's - this is not considered to be problematic, because projects would
be exclusively using automotive or consumer grade parts.

Support voltage control for regulators on ROHM BD71815 PMIC.
ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED).
Bucks 1 and 2 support HW state based voltage level and enable states. Other
regulators support HW state based enable states. All bucks and LDOs 1-5
allow voltage changes for RUN state and LDO4 can be enabled/disabled via
GPIO.
LDO3 does support changing between two predetermined voltages by using
a GPIO but this functionality is not included in this commit.
This work is derived from driver originally written by Tony Luo
