Subject: Re: [PATCH v8 2/3] MIPS: Loongson64: dts: update the display controller device node

Oh，sorry for that. This is what i am write for our downstream 4.19.190 kernel，I write it long time ago. It shouldn’t be included in this patch set. Please ignore that, I will remove it at next version.

I am sorry introduce “bug” again.
