Rafael J. Wysocki b899830506 platform/x86: intel-hid: Add missing ->thaw callback
The intel-hid driver is missing a PM ->thaw callback allowing the
device to go back to the operational state after creating a
hibernation image or when there is an image restoration error during
resume.

The lack of the ->thaw callback basically means that all events
signaled by the device are discarded after a hibernation image has
been created which may be problematic, for example, if the image
cannot be saved (eg. due to an I/O issue with storage).

Hans de Goede 1cd706df8a platform/x86: Add Intel Cherry Trail ACPI INT33FE device driver
The INT33FE ACPI device has a CRS table with I2cSerialBusV2 resources for
3 devices: Maxim MAX17047 Fuel Gauge Controller, FUSB302 USB Type-C
Controller and PI3USB30532 USB switch.

This commit adds a driver for this ACPI device which instantiates
i2c-clients for these, so that the standard i2c drivers for these chips
can bind to the them.

Carlo Caione 298747b757 platform/x86: hp-wmi: Fix detection for dock and tablet mode
The current driver code is not checking for the error values returned by
'hp_wmi_dock_state()' and 'hp_wmi_tablet_state()' before passing the
returned values down to 'input_report_switch()'. This error code is
being translated to '1' in the input subsystem, reporting the wrong
status.

The biggest problem caused by this issue is that several laptops are
wrongly reported by the driver as docked, preventing them to be put to
sleep using the LID (and in most cases they are not even dockable).

With this patch we create the report switches only if we are able to
read the dock and tablet mode status correctly from ACPI.

Michał Kępień 5959ddd02b platform/x86: fujitsu-laptop: account for backlight power when determining brightness
The comment for the get_brightness backlight device callback in
include/linux/backlight.h states that it should "return the current
backlight brightness (accounting for power, fb_blank etc.)".
fujitsu-laptop violates that premise by simply returning the value to
which ACPI function GBLL evaluates to.  Make sure 0 is returned when
backlight power is turned off.

Michał Kępień d75a4a972a platform/x86: fujitsu-laptop: do not log set_lcd_level() failures in bl_update_status()
Any set_lcd_level() call can fail for one of two reasons: either
requested brightness is outside the allowed range or the ACPI method
used for setting brightness level is not available.  For
bl_update_status(), the first case is handled by backlight core, which
means bl_update_status() will not even be called if requested brightness
is outside the allowed range.  The second case will be logged anyway by
set_lcd_level() itself, so there is no point in generating another
message in bl_update_status().  Remove the superfluous debug message
along with a local variable that is now redundant.

Due to the way the disable_brightness_adjust module parameter is
currently handled in acpi_fujitsu_bl_add(), it can only be set to either

Michał Kępień e06e4831d5 platform/x86: fujitsu-laptop: clean up use_alt_lcd_levels handling
The value of each module parameter can be changed on the fly via sysfs.
However, the current way of handling use_alt_lcd_levels prevents the
user from dynamically switching from a value of 0 or 1 back to
autodetection as the latter is only performed upon ACPI device
instantiation.  Fix this by moving autodetection (in a simplified form)
to set_lcd_level() and changing module parameter type to int.  Do not
announce autodetection results in a debug message as current value of
use_alt_lcd_levels can simply be read from sysfs.  Clarify module
parameter description.

Michał Kępień bd079a2cc5 platform/x86: fujitsu-laptop: sync brightness in set_lcd_level()
When using brightness keys and backlight device's sysfs interface
alternately, an incorrect input event might be generated for a
brightness key press.  Consider the following sequence of events:

 1. Set backlight brightness to 6 using brightness keys.
 2. Write 4 to /sys/class/backlight/fujitsu-laptop/brightness.
 3. Press the "brightness up" key.

The input event generated in this scenario would be KEY_BRIGHTNESSDOWN,
because before step 3 brightness_level would still be at 6.  As the new
brightness level is established using GBLL, it would evaluate to 5
(SBLL/SBL2 sets it to 4 in step 2 and pressing the "brightness up" key
increases it by 1).  This in turn would cause acpi_fujitsu_bl_notify()
to observe a 6 -> 5 change, i.e. a decrease in brightness, while screen
brightness would in fact be increased.

Fix this by updating brightness_level in set_lcd_level.

the latter, no vendor-specific ACPI calls should be made unless

Hans de Goede e5bf5df785 platform/x86: dell-laptop: Protect kbd_state against races
The kbd led code has multiple entry points each of which modifies the
kbd_state by reading it, modifying a copy, writing the copy and on
error setting the modified copy writing back the original state.

This is racy, so add a mutex protection the read-modify-write cycle
on each of the entry points.

Hans de Goede 504b02593f platform/x86: dell-*: Add a generic dell-laptop notifier chain
There are several cases where events handled in one of the dell-* drivers
need to be propagated to another dell-* driver.

This commit adds 3 generic functions:
dell_laptop_register_notifier()
dell_laptop_unregister_notifier()
dell_laptop_call_notifier()

It currently only defines 1 action:
DELL_LAPTOP_KBD_BACKLIGHT_BRIGHTNESS_CHANGED

Which is intended to propagate kbd_backlight_brightness_changed wmi
events from dell-wmi to dell-laptop (which contains the actual kbd
backlight driver).

These functions are put in dell-smbios as both dell-wmi and dell-laptop
use smbios functions and I do not want to put the notifier head in
either driver, as that will make the 2 drivers depend on each other.

Lukas Wunner b121b051d1 apple-gmux: Don't switch external DP port on 2011+ MacBook Pros
On MacBook Pros introduced 2011 and onward, external DP ports are
combined DP/Thunderbolt ports that are no longer fully switchable
between GPUs, they can only be driven by the discrete GPU.

More specifically, the Main Link pins (which transport the actual video
and audio streams) are soldered to the discrete GPU, whereas the AUX
Channel pins are switchable. Because the integrated GPU is missing the
Main Link, external displays appear to it as phantoms which fail to
link-train.

Force the AUX channel to the discrete GPU on these models to avoid any
confusion. Document the switching policy implemented by this commit.

Michał Kępień 979800e73d platform/x86: fujitsu-laptop: remove pf_device field from struct fujitsu_bl
Both struct fujitsu_bl and struct fujitsu_laptop have a pf_device field.
Up until now the latter has been redundant, which is logically incorrect
because the primary function of the platform device created by
fujitsu-laptop is to provide laptop-related (not brightness-related)
attributes to userspace.

Remove the pf_device field from struct fujitsu_bl and make all module
code use the pf_device field of struct fujitsu_laptop instead.

Michał Kępień 7a3319c1cd dell-led: move driver to drivers/platform/x86/dell-wmi-led.c
The dell-led driver handles a specific WMI GUID present on some Dell
laptops and as such it belongs in the x86 platform driver subsystem.
Source code is moved along with the relevant Kconfig and Makefile
entries, with some minor modifications:

  - Kconfig option is renamed from CONFIG_LEDS_DELL_NETBOOKS to
    CONFIG_DELL_WMI_LED,

  - the X86 Kconfig dependency is removed as the whole
    drivers/platform/x86 menu depends on it, so there is no need to
    duplicate it,

  - the name of the module's source file is removed from the header
    comment to avoid the need to update it in the future.

We are going to split <linux/sched/loadavg.h> out of <linux/sched.h>, which
will have to be picked up from a couple of .c files.

Create a trivial placeholder <linux/sched/topology.h> file that just
maps to <linux/sched.h> to make this patch obviously correct and
bisectable.

Include the new header in the files that are going to need it.

João Paulo Rechi Vita 71050ae7bf platform/x86: asus-wmi: Detect quirk_no_rfkill from the DSDT
Some Asus laptops that have an airplane-mode indicator LED, also have
the WMI WLAN user bit set, and the following bits in their DSDT:

    Scope (_SB)
    {
      (...)
      Device (ATKD)
      {
        (...)
        Method (WMNB, 3, Serialized)
        {
          (...)
          If (LEqual (IIA0, 0x00010002))
          {
            OWGD (IIA1)
            Return (One)
          }
        }
      }
    }

So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the
wlan state, it drives the airplane-mode indicator LED (through the call
to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF
(since wlan is ON), and vice-versa.

This commit skips registering RFKill switches at all for these laptops,
to allow the asus-wireless driver to drive the airplane mode LED
correctly through the ASHS ACPI device. Relying on the presence of ASHS
and ASUS_WMI_DSTS_USER_BIT avoids adding DMI-based quirks for at least
21 different laptops.

Paul Gortmaker af050abb5c platform/x86: intel_turbo_max_3: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/platform/x86/Kconfig:config INTEL_TURBO_MAX_3
drivers/platform/x86/Kconfig:   bool "Intel Turbo Boost Max Technology 3.0 enumeration driver"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

We do uncover some implicit includes during build coverage that
were hidden behind the module.h which pulls in a lot of dependants.
