My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

Hello Rob,

As mentioned in [3/5], this patch is also basd on Yong's patch:
message id: 20220407075726.17771-2-yong.wu@mediatek.com
Without this patch, some patches of this series will build failed.

Thanks!

BRs,
Rex

Need to define what they are and order.

Need to define each cell:

minItems: ??
maxItems: ??
items:
  items:
    - description: gce node
    - description: ...
    ...

Seems odd this property is optional...

Yes, I miss the required properties, will fix them.

Since my email server spam problem is fixed. I will send these binding
patches in my vdosys1 series [1]. (The fixes will be in the next
revision v18)

+description: |
+  ETHDR is designed for HDR video and graphics conversion in the external display path.
+  It handles multiple HDR input types and performs tone mapping, color space/color
+  format conversion, and then combine different layers, output the required HDR or
+  SDR signal to the subsequent display path. This engine is composed of two video
+  frontends, two graphic frontends, 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.
