Series TQMLS102xA: New display overlays and small fixes | expand

Commit Message

Alexander Stein April 8, 2025, 9:30 a.m. UTC 
This add an overlay for using the RGB-to-HDMI bridge.
Note: As DDC is directly connected to general I2C bus, there might be I2C
address conflicts. Hence not all displays might work.
