Hi, Nancy:

I've lost the v29 mail, so I reply in this mail for v29.
I got some message by make dt_binding_check.

/home/chunkuang/git/linux/Documentation/devicetree/bindings/display/mediatek/mediatek,ethdr.example.dtb:

> + designed for HDR video and graphics conversion in the external display path.
> + It handles multiple HDR input types and performs tone mapping, color

> + one video backend and a mixer. ETHDR has two DMA function blocks, DS and ADL.
> + These two function blocks read the pre-programmed registers from DRAM and
> + set them to HW in the v-blanking period.
