5516745311 platform-drivers-x86 for v5.3-1
ASUS WMI driver got a big refactoring in order to support the TUF Gaming
 laptops. Besides that, the regression with backlight being permanently off
 on various EeePC laptops has been fixed.
 
 Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
 X axis being inverted. This has been fixed.
 
 Intel PMC core driver has been extended to be ACPI enumerated
 if the DSDT provides device with _HID "INT33A1". This allows
 to convert the driver to be pure platform and support new hardware
 purely based on ACPI DSDT.
 
 From now on the Intel Speed Select Technology is supported thru
 a corresponding driver. This driver provides an access to the features
 of the ISST, such as Performance Profile, Core Power, Base frequency and
 Turbo Frequency.
 
 Mellanox platform drivers has been refactored and now extended
 to support more systems, including new coming ones.
 
 The OLPC XO-1.75 platform is now supported.
 
 CB4063 Beckhoff Automation board is using PMC clocks,
 provided via pmc_atom driver, for ethernet controllers in a way
 that they can't be managed by the clock driver. The quirk
 has been extended to cover this case.
 
 Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
 the information of Chuwi Hi10 Air has been fixed to cover more models
 based on the same platform.
 
 Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it
 has been provided. It required some extension of the generic WMI library,
 which allows to propagate opaque context to the ->probe() of the
 individual drivers.
 
 This release includes debugfs clean up from Greg KH for several drivers
 that drop return code check and make debugfs absence or failure non-fatal.
 
 Miscellaneous fixes here and there, mostly for Acer WMI and
 various Intel drivers.
 
 The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle:
 - 1dd93f873d platform/x86: asus-wmi: Only Tell EC the OS will handle display hotkeys from asus_nb_wmi

8eb835e478 power: avs: smartreflex: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

And even when not checking the return value, no need to cast away the
call to (void), as these functions were never a "must check" type of a
function, so remove that odd cast.

Move the olpc-ec driver away from the X86 OLPC platform so that it could be

which is also used on the ARM models, builds on this driver's interface.

It is actually plaform independent: the OLPC EC commands with their argument
and responses are mostly the same despite the delivery mechanism is
different.

813cab8f39 power: supply: core: Add CHARGE_CONTROL_{START_THRESHOLD,END_THRESHOLD} properties
Add POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD
and POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD properties, to expand
the existing CHARGE_CONTROL_* properties. I am adding them in order
to support a new Chrome OS device, but these properties should be
general enough that they can be used on other devices.

When the charge_type is "Custom", the charge controller uses the
POWER_SUPPLY_PROP_CHARGE_CONTROL_* properties as configuration for some
other algorithm. For example, in the use case that I am supporting,
this means the battery begins charging when the percentage
level drops below POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD and
charging ceases when the percentage level goes above
POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD.

v5 changes:
- Add the other missing CHARGE_CONTROL_* properties documentation in
  a separate commit
- Split up adding the charge types and adding the
  POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD and
  POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD properties into
  two different commits.
v4 changes:
- Add documentation for the new properties, and add documentation for
  the the previously missing charge_control_limit and
  charge_control_limit_max properties.

Add "Standard", "Adaptive", and "Custom" modes to the charge_type
property, to expand the existing "Trickle" and "Fast" modes.
I am adding them in order to support a new Chrome OS device,
but these properties should be general enough that they can be
used on other devices.

The meaning of "Standard" is obvious, but "Adaptive" and "Custom" are
more tricky: "Adaptive" means that the charge controller uses some
custom algorithm to change the charge type automatically, with no
configuration needed. "Custom" means that the charge controller uses the
POWER_SUPPLY_PROP_CHARGE_CONTROL_* properties as configuration for some
other algorithm.

9274c78305 power: supply: axp288_fuel_gauge: Add ACEPC T8 and T11 mini PCs to the blacklist
The ACEPC T8 and T11 Cherry Trail Z8350 mini PCs use an AXP288 and as PCs,
rather then portables, they does not have a battery. Still for some
reason the AXP288 not only thinks there is a battery, it actually
thinks it is discharging while the PC is running, slowly going to
0% full, causing userspace to shutdown the system due to the battery
being critically low after a while.

This commit adds the ACEPC T8 and T11 to the axp288 fuel-gauge driver
blacklist, so that we stop reporting bogus battery readings on this device.

  One division by zero fix in a specific driver and one core workaround
  for bad userspace behaviour from systemd regarding uevents. IMHO this
  can be considered to be a userspace bug, but the debug messages are
  useless anyways

349ced9984 power: supply: sysfs: prevent endless uevent loop with CONFIG_POWER_SUPPLY_DEBUG
Fix a similar endless event loop as was done in commit
8dcf32175b ("i2c: prevent endless uevent loop with
CONFIG_I2C_DEBUG_CORE"):

  The culprit is the dev_dbg printk in the i2c uevent handler. If
  this is activated (for instance by CONFIG_I2C_DEBUG_CORE) it results
  in an endless loop with systemd-journald.

  This happens if user-space scans the system log and reads the uevent
  file to get information about a newly created device, which seems
  fair use to me. Unfortunately reading the "uevent" file uses the
  same function that runs for creating the uevent for a new device,
  generating the next syslog entry

Both CONFIG_I2C_DEBUG_CORE and CONFIG_POWER_SUPPLY_DEBUG were reported
in https://bugs.freedesktop.org/show_bug.cgi?id=76886 but only former
seems to have been fixed. Drop debug prints as it was done in I2C
subsystem to resolve the issue.

Add the XO 1.5 compatible string too. This is actually not completely

"olpc,xo1-battery", but there are, in fact, differencies.

97ec136e71 power: supply: axp20x_usb_power: use polling to detect vbus status change
On AXP221 and later AXP PMICs that have the N_VBUSEN pin, when this pin
is high, either due to the PMIC driving it high or as an input, the VBUS
detection related interrupt mechanisms are disabled.

Previously this was worked around in the phy-sun4i-usb driver, which
needed to sense VBUS changes and report them to the musb driver in a
timely matter. However this workaround was only for the A31 and A33 type
USB PHYs. To support newer platforms we would have to enable it for
almost all the post-A31 SoCs.

However, since this is actually the result of the PMIC's behavior, the
workaround would be better if done in the PMIC driver, in this case the
VBUS power supply driver.

Add the same workqueue-based polling to the VBUS power supply driver.
The polling interval is chosen to be the debounce interval from the USB
PHY driver, as this short interval is needed in some cases, but the
power supply driver would not know when.
