This adds a driver for the ITE IT5570E EC in combination with Clevo
vendor EC firmware. The interface is mostly identical on various laptop
models. Thus, we have implemented one common driver to support them all.
The following features were implemented:
- Basics like battery, ac, etc.
- Suspend/hibernate support: S0ix, S3*, S4/S5
- Save/restore of keyboard backlight level during S0ix without the need
for Clevo vendor software (ControlCenter)
- Flexicharger
- Fn keys (backlight, volume, airplane etc.)
- Various configuration options via Kconfig / CMOS options
* Note: S3 support works at least on L140CU (Cometlake), but it's not
enabled for this board because S0ix is used.
Not implemented, yet:
- Type-C UCSI: the EC firmware seems to be buggy (with vendor fw, too)
- dGPU support is WIP
An example of how this driver can be hooked up by a board can be seen in
in change CB:59850, where support for the L140MU is added.
Known issues:
- Touchpad toggle:
The touchpad toggle (Fn-F1) has two modes, Ctrl-Alt-F9 mode and
keycodes 0xf7/0xf8 mode. Ctrl-Alt-F9 is the native touchpad toggle
shortcut on Windows. On Linux this would switch to virtual console 9,
if enabled. Thus, one should use the keycodes mode and add udev
rules as specified in [1]. If VT9 is disabled, Ctrl-Alt-F9 mode could
be used to set up a keyboard shortcut command toggling the touchpad.
- Multi-fan systems
The Clevo NV41MZ (w/o dGPU) has two fans that should be in-sync.
However, the second fan does not spin. This needs further
investigation.
[1] https://docs.dasharo.com/variants/clevo_nv41/post_install/
Testing the various functionalities of this EC driver was done in the
changes hooking up this driver for the boards.

Simplify the implementation of setting the keyboard backlight PWM
value. Host command stubs typcially don't need to examine the host
command's return value as stored in cmd_code because that level of
detail is not very interesting. Higher value error codes are returned in
actual result structures.
This host command can return EC_RES_ERROR for out of range PWM values
which is already a generic error and unlikely to happen since we already
limit the range to 0..100 here. Finally, none of the callers in coreboot
check the return value.
