[PATCH 2/2] ARM: dts: imx7: add MIPI-DSI support

From: Roland Hieber
Date: Mon Nov 27 2023 - 11:13:39 EST


From: Marco Felsch <m.felsch@xxxxxxxxxxxxxx>

This adds the device tree support for the MIPI-DSI block. The block can
be used as encoder for the parallel signals coming from the lcdif block.
