We are having a imx8m mini based customboard we want to port MIPI DSI based st7703 lcd panel driver at uboot and display splash screen.
1. We are able to port the st7703 driver (taking reference of rm67191 driver) with uboot 2020 version for our board as well. Probe is getting call and please see the logs, video-link is being created with lcdif, video bridge and panel.
2. Since the mipi panel is already working in the kernel, so we kind of ported the clock values as well. But as attached in clk-dump the usecnt is 0 for all the display related clocks.
3. We also see in imx8mm.dtsi file there is display-subsystem node, whose compatible string matches with the drm core. But in uboot we do not have support for it. Do we need to add that?
Currently everything is working fine, but somehow the clock is not getting init. We also probed the hardware and we do not see the clk with the probe too
