Adding new column to the table - Machine Type
Hi, I'd like to add new column to the tables and fill Machine Types at least for most recent laptops. It is very helpful while identifying the laptop. May I? Probably as a 2nd column. Also I'd like to recommend using the official Product Specification Reference site for the specifications, etc.

Thinkpad P14s Gen 2 touch support
The table lists compatibility with everything available except for touchscreen in the wiki. Fedora supports touch on kernel 5.14 for this model but I have been unable to get it functional on arch LTS 5.16 and base kernel 5.16. I have also been unable to locate any information on getting it to work, only seeing it work on my fedora USB. If I figure it out before anyone else I will post solution, but if anyone had any information to link to the entry or add I'd be eternally grateful. The kernel is recognizing its existence in devices files and I even have the driver for it but dmesg says it has a dummy regulator and all the packets it sends are invalid.

Battery conservation mode should list ACPI method
As described in Lenovo_IdeaPad_3_15alc6_(AMD)#Battery_conservation_mode. In turn that page should probably mention the `ideapad_laptop` module. (although really they should be merged)
Adding new row to the "Legion series" table.
Brightness control does not work with AMD Ryzen when using hybrid graphics on Lenovo Legion laptops Legion Slim 7 (2021, 15ACH6) on kernel 6.1.4+.
On models with the Nvidia WMI EC backlight interface, when the laptop is configured in dynamic mux mode in the BIOS the backlight should always be controlled by the Nvidia WMI EC backlight interface.
But, on some Lenovo Legion laptop models (Legion Slim 7 15ACH6, 2021), due to a bug, the backlight might be driven by either one of nvidia_wmi_ec_backlight or amdgpu_bl0 at different times.
As a workaround, starting from 6.1.14+ added a force module parameter which can be used with acpi_backlight=native to restore the old backlight behavior.
If backlight control does not work correctly on kernel 6.1.14+, 6.3.2+ pass acpi_backlight=native and nvidia_wmi_ec_backlight.force=1 as kernel parameters.
