Historically, ChromeOS devices have worked around the problem of OEMs
using several different parts for touchpads/touchscreens by using a
ChromeOS kernel-specific 'probed' flag (rejected by the upstream kernel)
to indicate that the device may or may not be present, and that the
driver should probe to confirm device presence.
Since c636142b, coreboot now supports detection for i2c devices at
runtime when creating the device entries for the ACPI/SSDT tables,
rendering the 'probed' flag obsolete for touchpads. Switch all touchpads
in the tree from using the 'probed' flag to the 'detect' flag.
Touchscreens require more involved power sequencing, which will be done
at some future time, after which they will switch over as well.
TEST: build/boot at least one variant for each baseboard in the tree.
Verify touchpad works under Linux and Windows. Verify only a single
touchpad device is present in the ACPI tables.

Add an enum for `DdiPortXConfig` devicetree options. Note that setting
these options to zero does not disable the corresponding DDI port, but
instead indicates that no LFP (Local Flat Panel, i.e. internal LCD) is
connected to it.

Add new board Clevo L14xMU (TGL).
GPIOs were configured based on schematics.
Tested and working:
- On-board RAM (M471A1G44AB0-CWE)
- DIMM slot (tested Crucial CT16G4SFD8266.16FJ1 / MTA16ATF2G64HZ-2G6J1)
- Graphics (GOP driver), including HDMI
- Keyboard
- I2C touchpad (including interrupt)
- TPM (with interrupt on Windows, only polling on Linux [1])
- microSD Card reader
- both NVME ports
- Speakers
- Microphone
- Camera
- WLAN/BT (CNVi)
- All USB2/3 ports including Type-C
- Thunderbolt detects my work laptop in TB Control Center
(I couldn't test anything more due to security policy.)
- TianoCore
- internal flashing with flashrom on vendor firmware
Note on TPM:
The vendor sets Intel PTT to default-on in newer CSME images, which
conflicts with the dTPM. Currently, there are two ways to make it work:
1) Boot vendor firmware once to let it disable PTT via CSME firmware
feature override.
2) Use Intel Flash Image Tool (FIT) to set "initial power-up state" to
disabled.
Boots fine:
- Debian testing, unstable (Linux 5.16.14, 5.17.0-rc6)
- Windows 10 21H2 (Build 19044.1586)
Untested:
- Thunderbolt (see above)
- Type-C DisplayPort
- S-ATA
Doesn't work:
- TPM interrupt on Linux [1]
- All EC related functions - EC driver is WIP
- WLAN/BT (PCIe) - gets detected but can't be enabled
- 3G/LTE (not powered without EC driver)
- Fn-Keys
- S0ix
- UCSI
- Fan control
- Battery info
