From: Aditya Swarup <[email protected]> RKL doesn't have DSI outputs, so we shouldn't try to read out the DSI transcoder registers.
v2(MattR): - Just set the 'extra panel mask' to edp | dsi0 | dsi1 and then mask against the platform's cpu_transcoder_mask to filter out the ones that don't exist on a given platform. (Ville) v3(MattR): - Only include DSI transcoders on gen11+ again. (Ville) - Use for_each_cpu_transcoder_masked() for loop.
