Hii,
I am working with ti-processor-sdk-linux-am57xx-evm on DRA7xx_EVM. I have changed the entire dts file according toDRA7xx_EVM hardware. I am not getting anything on the dispaly. I am getting display subsystem successfully initialized in the Kernel Log
[ 0.363848] OMAP DSS rev 6.1
[ 0.364094] omapdss_dss 58000000.dss: bound 58001000.dispc (ops dispc_component_ops)

If i do modetest then i am getting like this, i suspect there is some issue with connector ids because when i worked on dra7xx, then connector ids are different please help me with this....
