72628fa813 mb/lenovo: Enable MEI on Sandy Bridge ThinkPads
It was already enabled on T520 and L520, but disabled on X220, T420 and
T420s.

On X220, it was disabled by commit 0793afe9 (mb/lenovo/x220: disable ME).
I can't reproduce those issues today on linux 4.4 and linux 5.13.

Also, it breaks the me_disable feature, we already have a Kconfig option
to hide MEI in case of errors, and it will be hidden on disabled,
recovery, firmware update paths anyway.

All mainboards use the same values for AC and battery, even desktop
boards without a battery. Use the AC values everywhere and drop the

This is intentional so as to ease reviewing the devicetree changes.

Also update util/autoport accordingly.

d07ac8ee13 drivers/intel/gma: Ditch link_frequency_270_mhz setting
The `link_frequency_270_mhz` setting was originally used by the native
graphics init code for Sandy/Ivy Bridge, which is long gone.

The value of this information (which board had it set) is questionable.
The only board that had an LVDS panel and set it to 0 was the ThinkPad
L520, where native graphics init was never reported to work. Also, the
native graphics init only used it for calculations, but never confi-
gured the hardware to use a specific frequency. A look into the docu-
mentation also doesn't reveal any straps that could be used to confi-
gure it.

b30a47b841 sb/intel/{bd82x6x|ibexpeak}: Drop p_cnt_throttling_supported
The processor P_BLK doesn't support throttling. This behaviour could be
emulated with SMM, but instead just update the FADT to indicate no support
for legacy I/O based throttling using P_CNT.

We have _PTC defined in SSDT, which should be used in favour of P_CNT by
ACPI aware OS, so this change has no effect on modern OS.

Drop all occurences of p_cnt_throttling_supported and update autoport
to not generate it any more.

db27e3384a mb/lenovo/t*00/romstage: Switch to new hybrid driver
Get rid of old hybrid graphics driver and use the new one.

1. Disable IGD and PEG in early romstage.
 The PEG port will get disabled on devices that do not have a

 The disabled IGD does no longer waste GFX stolen memory.

2. Get rid of PCI driver
 The Nvidia GPU can be handled by the generic PCI driver and allows
 to use the ACPI _ROM generator for Switchable graphics.

3. Settings are stored in devicetree.
 One driver for all Lenovo hybrid graphics capable devices.

4. Add support for Thinker1 GPU power handling.
 Only boards that do use reference design 2012 are known to be
 supported. Needs test on boards that do you use reference design 2013.
 Should reduce idle power consumption when using IGD by ~5Watt.

Tested on Lenovo T430 without DGPU. PEG port is disabled.
Needs test on all devices.
