Alexei Sorokin has uploaded a new patch set (#26) to the change originally created by Alexander Couzens. ( https://review.coreboot.org/c/coreboot/+/28950?usp=email )
Change subject: mb/lenovo/x230: introduce EDP variant
......................................................................
mb/lenovo/x230: introduce EDP variant
There is a modification for the x230 which uses the 2nd DP from the
dock as the integrated panel's connection, which allows using a custom
eDP panel instead of the stock LVDS display.
There are several adapter boards present on the market and all of them
use the same method of enabling the custom eDP panel.
To make this work with coreboot, the internal LVDS connector should be
disabled in libgfxinit. Additionally, VBT has been modified to keep
brightness controls functional on the adapter boards that use LVDS for
the job.
The modifications done to the VBT are:
- Remove the LVDS port entry.
- Move the DP-3 (which is the 2nd DP on the dock) entry to the first
position on the list.
- Set the DP-3 as internally connected.
This has been reported to work with the following panels:
- LP125WF2-SPB4 (1920*1080, 12.5")
- LQ125T1JW02 (2560*1440, 12.5")
- LQ133M1JW21 (1920*1080, 13.3")
- LTN133HL10-201 (1920*1080, 13.3")
- B133HAN04.6 (1920*1080, 13.3")
- B133QAN02.0 (2560*1600, 13.3")
Other eDP panels not on this list should work as well.
