Add MSI Katana GF66 11UC support

[jastisriradheshyam]

How I tested: by setting values at the mentioned paths and observing the behavior and also observing ec realtime values (sudo watch -n 0.1 hexdump -C /dev/ec)

Tested & Working

• WebCam:/sys/devices/platform/msi-ec/webcam
• WebCam Block:/sys/devices/platform/msi-ec/webcam_block
• Battery mode: /sys/devices/platform/msi-ec/battery_mode
• Cooler booster: /sys/devices/platform/msi-ec/cooler_boost
• CPU Realtime temperature: /sys/devices/platform/msi-ec/cpu/realtime_temperature
• GPU Realtime temperature: /sys/devices/platform/msi-ec/gpu/realtime_temperature
  • Also verified from NVIDIA application.
  • Value was non zero when I was utilizing GPU
• GPU Realtime Fan Speed: /sys/devices/platform/msi-ec/gpu/realtime_fan_speed
  • Value was non zero when I was utilizing GPU
• Fan Mode: /sys/devices/platform/msi-ec/fan_mode
  • auto, silent and advanced
• Firmware version: /sys/devices/platform/msi-ec/fw_version
• Firmware version release date: /sys/devices/platform/msi-ec/fw_release_date
• keyboard backlight:/sys/class/leds/msiacpi::kbd_backlight/brightness
• Mic Mute LED: /sys/class/leds/platform::micmute/brightness
• Mute LED: /sys/class/leds/platform::mute/brightness
• Charge Threshold: /sys/class/power_supply/BAT1/charge_control_end_threshold
• Shift Mode: /sys/devices/platform/msi-ec/shift_mode
  • I was able to set values without error and the value is set to sport on startup (In BIOS, if user scenario is set to Performance Mode)
  • and value is set to comfort on startup (In BIOS, if user scenario is set to Balanced Mode)
  • Verified on Windows

  • In Windows	In MSI-EC Driver	Value
    Turbo	Turbo	C4
    High	Sport	C0
    Medium	Comfort	C1
    Low	Eco	C2

Not sure if it's working right

• CPU Realtime Fan Speed: /sys/devices/platform/msi-ec/cpu/realtime_fan_speed
  • The address might be correct and the value definitely correlates to speed of the fan but also one time it got stuck at 0x55 even the speed of the fan speed got slow, so not sure what's the about this configuration
  • But the value has gone up to 0x55 and rt_fan_speed_base_max is set to 0x37, so if it goes beyond the 0x37 then it starts showing Invalid argument
  • I believe the rt_fan_speed_base_min should be 0x00 -> 0 and rt_fan_speed_base_max be 0x64 -> 100

Not supported

• function windows button swap: /sys/devices/platform/msi-ec/fn_key & /sys/devices/platform/msi-ec/win_key
  • I was not able to see this feature in either MSI control panel in Windows and MSI official docs for the particular laptop model and also tried with the values set in existing conf's just to sure but it did not worked.
