Is there any way to adjust HDMI drive current?

The Parker TRM section 28.8.21 indicates that SOR_NV_PDISP_SOR_LANE_DRIVE_CURRENT register
can be used to adjust the drive current. There doesn’t seem to be any reference to this
in the HDMI device tree or driver, although it seems to be referenced in the DP driver.

Is there any simple way to adjust this when the SOR is being used for an HDMI application?

Thanks in Advance,

Cary

cobrien,

Only old driver supports this one. K3.10 driver source may have this one but it is definitely not able to apply to rel-28.2.

May I ask what usecase needs to modify the drive current?
