Hello Gajanan,
I'm trying to run linux on a
valleyview hardware, which was made by my company.
On this hardware, the display panel is connected via
eDP, but the panel timings / resolution is not available
in the EDID of the eDP. It is only available via VBT.
You added once eDP support to VLV, can you
give me some information on the following questions:
Is there a way to force the i915.ko to get the
panel timing / resolution for the eDP from the
VBT and not via i2c from the eDP?
Can you give me some advice, how to add this
option to the source files of i915.ko?
I'm using 3.14.29, but I have also tried 4.0.0-rc7.
Best regards
Andreas
