2019-10-20mb/lenovo/x200: Add ThinkPad X301 as a variantBill XIE
It is similar to X200s, with U-series CPU, slightly different gpio setup, no docking support, and no superio chip. Tested: - CPU Core 2 Duo U9400 - Slotted DIMM 4GiB*2 from samsung - Camera - pci-e slots - sata and usb2 - libgfxinit-based graphic init - NVRAM options for North and South bridges - Sound - Thinkpad EC - S3 - Linux 4.19.67-2 within Debian GNU/Linux stable, loaded from Linux payload (Heads) and Seabios. TODO: repurpose and/or rename flag H8_DOCK_EARLY_INIT (introduced in CB:4294 ) for h8-using devices without a dock.

2018-12-11mb/intel/x200: Add data.vbtArthur Heymans
There are 2 vendor BIOS's for the Lenovo X200 with the difference being the settings in the VBT blob to accommodate different backlight frequencies. Linux however sticks with the setting set by the firmware. Tested on Lenovo X200 with CCFL backlight.

2017-05-03nb/intel/gm45: Set display backlight according to EDID stringArthur Heymans
Add some known good values for some thinkpads displays. Known good means that at this pwm frequency the display is evenly lit on all duty cycles, the display makes minimal to no noise at lower duty cycles and the display does not flicker. This values differs from vendor (which uses an obviously wrong display clock (190MHz instead of 320MHz) resulting in frequency more than 60% off the intended value. TESTED on Thinkpad X200 with edid ascii string in list and removed from list to see if notice message is shown.
