Subject: [PATCH v1 0/1] drm/imx/dcss: Add interconnect support

This allows us to raise DRAM bandiwth to a high enough value for a
stable picture on i.mx8mq. We pick a bandwidth that should be sufficient
for 4k@60Hz.

This was tested on a Librem 5 with the (not yet) mainline mhdp DP controller.
Without that initial boot works fine but e.g. fb unblank results in a cyan
screen.

Modelled like mdp5_kms.
