However, the DIU is already initialized in u-boot and we can rely
on the settings in u-boot for corenet platform,

I don't like that at all.

[Jason Jin-R64188] What's the potential issue of this? Most of the IPs
need the platform initialization in u-boot. For example, the hwconfig
in u-boot used for board specific settings for most platform.

The potential problem is that it's not stable.  Power management breaks
your code.

I won't NACK your patch, but it feels like a band-aid rather than a real
solution.

[Jason Jin-R64188] Thanks. The power management will break the pixel clock only. We can try to fix it separately. I'll try to explain it in that mail.
