Add interconnect support to mxsfb so that it is able to request enough
bandwidth to DDR for display output to work.

Guido Gunther authored 4 years ago and Martin Kepplinger committed 3 years ago

This allows us to manage bandwidth requests. We pick
a bandwitch for 4k@60Hz until we figure out a better value.
Main point is to be able to force high DRAM frequency.

not yet mainline

this should be ready when the labels are a stable interface / documented.

these should probably become named gpios if needed

we should not need this!

it adds an unnecessary regulator

This avoids the tearing we've so far worked around by
halfing the pixel clock in the mxsfb driver.

without this, we see "failed to enable ep0out" during boot and no
gadget would work.

This fixes g_multi gadget functionality like the ACM serial console.

Due to current spikes during boot the USB-C VBUS can get drawn down too
low causing the bq25890 to reset the board. Allow VBUS to drop a bit
further to make allowance for thses spikes.
