Hi all,
I'm using kernel PSP (04.04.00.02)release with dm38x, and while loading hdmi driver i'm getting the following error log.
" I2C Bus Low? HDMI failed to read E-EDID"

From the code its checking the 6th bit of DDC_STATUS what is the base address of the register.?
what could be the problem, my hdmi sda & clk are pulled high.
