Running 'bare metal' can anyone tell me the minimum subset IPU etc components that have to be initialised to display a frame store via hdmi.. The SDK goes part way there, but includes a whole host of stuff to initialise parallel connected panels too, and I fear I'm getting lost in the detail.
I think, in particular, where does the HDMI specifically get its data from .. is it a synchronous interface in DP.. if so which? .. OK.. answered that bit: found the IOMUXC_GPR3 bits that connect hdmi to one of the IPU channels.
Thanks in advance.. John

exactly where control signals originate.. and especially which
'elements' are involved in setting the pixel clock given to the external
