a9b2f8e2fa tools/power/x86/intel-speed-select: Auto mode for CLX
There is an expectation in the CLX platform for SST base-freq feature that
Scaling min frequency be different for high and low priority cores.
This is the way the firmware will understand the priority.

So this change will look at high priority and low priority cores, and set
scaling_min_freq to P1High for high priority cores and P1Low to low
priority cores.

91d928147b tools/power/x86/intel-speed-select: Correct CLX-N frequency units
In CLX_N base_frequency is read from cpufreq sysfs, where units are in
KHz. The internal units in the code matches the real ratios which are
in 100MHz scale. So when storing units for CLX-N frequencies, convert
to 100MHz scale.

4a8d82cdec platform/x86: intel_int0002_vgpio: Pass irqchip when adding gpiochip
We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.

For chained irqchips this is a pretty straight-forward
conversion. This driver requests the IRQ directly in the driver
so it needs to pass a NULL parent handler. We may revisit this
code later and pull reqular shared IRQ handler into
gpiolib, so leave a FIXME.

Enable command also have support for --auto|-a option, which sets cpufreq
scaling_min to max, so that the high priority base frequency can be the
required minimum for high priority cores. Disable command with -a/--auto
option reset the setting back to the min frequency.

The turbo-freq feature is dependent on the core-power feature. If the
core-power feature is disabled while the turbo-freq feature is enabled,
this will break the turbo-freq feature. This is a firmware limitation,
where they can't return error under this scenario.

So when trying to disable core-power, make sure that the turbo-freq
feature is not enabled. If it enabled, return error if user is trying to
disable the core-power feature.

a6a82f9bcd tools/power/x86/intel-speed-select: Turbo-freq feature auto mode
Introduce --auto|-a option to turbo-freq enable feature, so that it
does in one step for users who are OK by setting all passed target cores
as high priority and set in CLOS 0 and remaining in CLOS 3. In this way,
users don't have to take multiple steps to enable turbo-freq feature. For
users who want more fine grain control, they can always use core-power
feature to set custom CLOS configuration and assignment.

While here also print the error to output when clos configuration fails.

For example
intel-speed-select -c 0-4 turbo-freq enable --auto

The above command will enable turbo-freq and core-power feature. Also
mark CPU 0 to CPU 4 as high priority.

79e29cb8fb platform/mellanox: Add bootctl driver for Mellanox BlueField Soc
This commit adds the bootctl platform driver for Mellanox BlueField
Soc, which queries secure state and controls the eMMC boot partition
swapping by sending SMC calls to ATF running at EL3.

Below are the sequences of typical use case.

  1. User requests boot partition swapping, which could be on-demand or
     during boot-image upgrade via UEFI capsule;

  2. This bootctl driver handles the request and sends SMC call
     to ATF. ATF programs register BREADCRUMB0 which has value
     preserved during warm reset. It also programs eMMC to swap
     the boot partition;

  3. After software reset (rebooting), ATF BL1 (BootRom) checks
     register BREADCRUMB0 and enable watchdog if configured;

  4. If booting fails, the watchdog timer will trigger rebooting.
     In such case, ATF Boot ROM will switch the boot partition
     back to the previous one. This is a robust feature and used
     to prevent failure during boot partition upgrade.

c656829f07 platform/x86: toshiba_acpi: do not select INPUT_POLLDEV
The driver does not use polling mode of input devices, and this config
option is going away, so let's not reference it.

60d1509533 platform/x86: peaq-wmi: switch to using polled mode of input devices
We have added polled mode to the normal input devices with the intent of
retiring input_polled_dev. This converts peaq-wmi driver to use the
polling mode of standard input devices and removes dependency on
INPUT_POLLDEV.

Because the new polling coded does not allow peeking inside the poller
structure to get the poll interval, we change the "debounce" process to
operate on the time basis, instead of counting events.

We also fix error handling during initialization, as previously we leaked
input device structure when we failed to register it.

10b65e2915 platform/x86: dell-laptop: disable kbd backlight on Inspiron 10xx
This patch adds a quirk disabling keyboard backlight support for the
Dell Inspiron 1012 and 1018.

Those models wrongly report supporting keyboard backlight control
features (through SMBIOS tokens) even though they're not equipped with
a backlit keyboard. This led to broken controls being exposed
through sysfs by this driver which froze the system when used.

Introduce quirks and module parameters. 3 quirks are added:
1. Fixes reporting brightness keys twice since it's already handled by
   acpi-video.
2. Some models need a short delay when setting battery thresholds to
   prevent a race condition when two processes read/write. (will be used later)
3. Matebook X (2017) handles micmute led through the "legacy" interface
   which is not currently implemented. Use ACPI EC method to control
   this led. (will be used later)

2 module parameters are added to enable this short delay and/or report
  brightness keys through this driver.

Move from WMI driver to platform driver. This move is necessary since
the driver is no longer a hotkeys driver only. Platform driver makes it
easier for users to access sysfs attributes under (i.e.
/sys/devices/platform/huawei-wmi) compared to wmi driver.

Use WMI device UID, AMW0 has a UID of HWMI. WMI0 is the device name
and doesn't have a UID so keep it as it is.

    directory. Having the open functions there do the lockdown checks.
 
  - Fixed a few races with opening an instance file and the instance being
    deleted (Discovered during the locked down updates). Kept separate
    from the clean up code such that they can be backported to stable
    easier.
 
  - Cleaned up and consolidated the checks done when opening a trace
    file, as there were multiple checks that need to be done, and it
    did not make sense having them done in each open instance.
 
  - Fixed a regression in the record mcount code.
 
  - Small hw_lat detector tracer fixes.
 
  - A trace_pipe read fix due to not initializing trace_seq.
