Pull ARM SoC platform updates from Olof Johansson:
"SoC changes, a substantial part of this is cleanup of some of the
older platforms that used to have a bunch of board files.
In particular:
- Remove non-DT i.MX platforms that haven't seen activity in years,
it's time to remove them.
- A bunch of cleanup and removal of platform data for TI/OMAP
platforms, moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
There are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones are:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP"

"Just a single change to revert enablement of packet error checking for

power: supply: sbs-battery: chromebook workaround for PEC
|
|
Looks like the I2C tunnel implementation from Chromebook's
embedded controller does not handle PEC correctly. Fix this
by disabling PEC for batteries behind those I2C tunnels as
a workaround.
Note, that some Chromebooks actually have been reported to
have working PEC support (with I2C tunnel). Since the problem
has not yet been fully understood this simply reverts all
Chromebooks to not use PEC for now.

Some fault events like the over-current condition will get resolved
by the hardware, by e.g. disabling the port. As the status in the
interrupt status register is cleared on read when the fault is resolved,
the sysfs health property will only contain the correct health status
for the first time it is read after such an event, even if the actual
fault condition (like a VBUS short) still persists. To reflect this
properly in the property we cache the last health status and only update
the cache when a actual change happens, i.e. the ERR bit in the status
register flips, as this one properly reflects a continued fault condition.
The ALERT pin however, is not driven by the ERR status, but by the actual
fault status, so the pin will change back to it's default state when the
hardware has automatically resolved the fault by cutting the power. Thus
we never get an IRQ when the actual fault condition has been resolved and
the ERR status bit has been cleared in auto-recovery mode. To get this
information we need to poll the interrupt status register after some time
to see if the fault is gone and update our cache in that case.
To avoid any additional locking, we handle both paths (IRQ firing and
delayed polling) through the same single-threaded delayed work.

Samsung S3C24xx and S3C64xx machine code cleanup for v5.10
Big cleanup for the Samsung S3C24xx and S3C64xx platforms, although it
also touches files shared with S5Pv210 and Exynos. This is mostly Arnd
Bergmann work which Krzysztof Kozlowski took over, rebased and polished.
The goal is to cleanup, merge and finally make the Samsung S3C24xx and
S3C64xx architectures multiplatform. The multiplatform did not happen
yet here - just cleaning up and merging into one arch/arm/mach-s3c
directory. However this is step forward for multiplatform or at least
to keep this code still maintainable.
This pulls also branch with changes for Samsung SoC sound drivers from
broonie/sound because the cleanups there were part of this series and
all further patches depend on them.

Additionally, a translation table is needed between the text representation
of the extcon cable names and their IDs is needed. In order to retain DT
compatibility, TA and CHARGE-DOWNSTREAM are added as they were present up
until commit 11eecf910bd8 ("extcon: Modify the id and name of external
connector")

Prevents direct charging control in cable notification and only set the
input current limit according to cable type. Leave the enabling of
charing to cm_monitor() where charging management proceeds. We may lose
a few ms to enable charging compared to before, but it's more important
that charging is enabled always in safe context.

cm_monitor(), where charging management starts, checks various charging
condition sequentially to decide next charging operation. However, as it
follows sequential process, cascaded if statements, it does some
jobs which have already done in the previous stage. This results in a
delay in decision making. Moreover, starting point of charging is spread
all around which makes maintain code and debugging difficult.
Both of the problems mentioned above become clean if it manages battery
charging focusing on battery status not following sequential condition
checking. Now, cm_monitor() moves battery state diagram and does the
optimal operation for current state. As a result, it reduces whole
monitoring time almost in half.

Current charger-manager calls power_supply_changed() whenever charging
status is changed. Remove the separated power_supply_changed() calls
and let it be called at end of try_charger_enable() function which
is called to set charging/discharging.

The POWER_SUPPLY_CHARGE_NOW/FULL property reflects battery's charges
in uAh unit, but charger-manager has been used it wrongly as a
status field.

We were using POWER_SUPPLY_PROP_TEMP if the temperature was coming
via the fuel gauge and POWER_SUPPLY_PROP_TEMP_AMBIENT if it was
coming via the thermal framework. Since they're mutually
exclusive in the driver and we don't know if the thermal framework
is ambient or not, unify them both to use POWER_SUPPLY_PROP_TEMP.

cm_notify_event() was introduced to get an event associated with the
battery status externally (ie in board files), but no one ever used it.
Moreover it makes charger manager driver more complicated. Drop the
function and all data related to it to simplify the driver.

Whenever the battery status is changed, charger manager triggers a uevent
through a private interface. Modify it to use power_supply_changed()
since it belongs to the power supply subsystem.

Both chips have charger and a fuel gauge.
This adds basic support for displaying the state of the battery and the
input power, settings are not modified. There are some defaults set via
OTP.
Charging also starts after plugging USB.
Known issues of the fuel gauge: There are drivers in the wild which disable
the fuel gauge at shutdown. If a kernel is booted without fuel gauge
support, after such a driver has been used, the fuel gauge will stay off
and decalibrate.
If this driver is used after that, it might display wrong values for charge
level.

Current sbs-battery considers all smbus errors as disconnection events
when battery-detect pin isn't supplied, and restored to present state back
when any successful transaction is made.
This can lead to unwanted state changes between present and !present
when there's one i2c error and other following commands were successful.
This patch provides a unified way of checking presence by calling
sbs_get_battery_presence_and_health() when detect pin is not used.
