Crystal Cove and Whiskey Cove are two different PMICs which are
installed on Intel Atom SoC based platforms.
Moreover there are two independent drivers that by some reason were
supposed (*) to get into one kernel module.
Fix the mess by clarifying Kconfig option for Crystal Cove and split
Whiskey Cove out of it.
(*) It looks like the configuration was never tested with
INTEL_SOC_PMIC=n. The line in Makefile is actually wrong.

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.

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.

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.

FUNC subfunction 0x1000 is currently referred to as FUNC_RFKILL, which
is misleading, because it handles more than just radio devices (also
lid, dock, LEDs). Rename the FUNC_RFKILL constant to FUNC_FLAGS.
Replace "rfkill" with "flags" in the names of its associated fields
inside struct fujitsu_laptop.

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.

brightness is changed through the hotkey.

a workqueue if it needs to sleep, make use of this and remove a bunch
of DIY code for this.
Since this commit removes the workqueue usage for LEDs, the

There is no need to set the led_classdev's brightness value from
its set_brightness callback, this is taken care of by the led-core and
thinkpad_acpi really should not be mucking with it.
Note that kbdlight_set_level_and_update() is still used by the old
thinpad_acpi specific sysfs interface for the led, so we cannot
remove it.

The same method to activate LM(Launch Manager) can also be used to
activate the RF Button driver with different bit toggled in the same
lm_status. To express that many functions this byte field can achieve,
rename the lm_status to app_status. And also the app_mask is the bit
mask which specifically indicate which bits are going to be changed.
This solves a problem where the AR9565 wifi included in the
Acer Aspire ES1-421 is permanently hard blocked according to the rfkill
GPIO read by ath9k.

Some Asus machines use 0x4/0x5 as their LED on/off values, while others
use 0x0/0x1, as shown in the DSDT excerpts below. Luckily it seems this
behavior is tied to different HIDs, after looking at 44 DSDTs from
different Asus models.
Another small difference is that a few of them call GWBL instead of
OWGS, and SWBL instead of OWGD. That does not seem to make a difference
for asus-wireless, and is additional reasoning to not try to call these
methods directly.

This patch adds the PCI Device id for Power Management Controller on Intel
Apollo Lake platforms.
Intel PMC IPC Driver loads as a platform driver on Apollo Lake platforms
since Intel BIOS hides the PCI Configuration space for 0:13:1 and
re-enumerates it as ACPI device (INT34D2). The correct PCI Device ID should
be added if some platform firmware choses to enumerate the device via PCI
space.

This patch adds a new API to indicate S0ix residency in usec. It utilizes
the PMC Global Control Registers (GCR) to read deep and shallow
S0ix residency.
PMC MMIO resources:
o Lower 4kB: IPC1 (PMC inter-processor communication) interface
o Upper 4kB: GCR (Global Control Registers)
This enables the power management framework to take corrective actions when
the platform fails to enter S0ix after kernel freeze as part of the suspend
to idle flow. (echo freeze > /sys/power/state).
This is expected to be used with a S0ix failsafe framework such as:
