[PATCH v2 0/3] MediaTek MT8195 display binding

[PATCH v2 0/3] MediaTek MT8195 display binding

[Rex-BC Chen]

Add this series to present MediaTek display binding for MT8195.
The reason I send this series is Jason and Nancy's binding patches are
never received by devicetree mail server.
Therefore, I help them to resend binding patches.

Changes for v2:
1. This patch is based on linux next-20220506.
2. Jason's patches are accepted and I drop them.

Use a generic node name, as Devicetree spec asks:
"The name of a node should be somewhat generic, reflecting the function
of the device and not its precise programming

model. If appropriate, the name should be one of the following choices:"

I proposed dma-controller, but feel free to find better generic node name.

Best regards,
Krzysztof

Use a generic node name, as Devicetree spec asks:
"The name of a node should be somewhat generic, reflecting the function
of the device and not its precise programming

model. If appropriate, the name should be one of the following choices:"

I proposed dma-controller, but feel free to find better generic node name.

Krzysztof

dma-controller is covered by dma-controller.yaml, which references
dma-common.yaml in its entirety, so I don't think that would work.

What about "blitter"? I think that is a generic term that is/was commonly
used with display hardware and sort of describes the function of the RDMA
& WDMA blocks, and if only one side is memory and the other is the display
pipeline.

Hello Krzysztof and Chen-Yu,

Nancy thinks our IP is more like rdma.
Blitter may be somthing for reading memory and writing to another
memory, but we don't have the function of writing memory.
If we use rdma, is it ok?

BRs,
Rex

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

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.

+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.

+  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

+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.

That's mediatek-drm, and this refers to the HDR block in the display IP...

Though, I have no idea of what "ET" stands for in "ETHDR", so, it would be
definitely nice if MediaTek can write the meaning in the description, like

description:
   ETHDR (E??? T??? High Dynamic Range) is designed for HDR video and ...blah

Hello Krzysztof and Angelo,

"ET" is actually meaningless.
ET is one of mediatek departments and it's where the engine from.
Therefore, I think we will add description like this:

Rex

Sure, sounds good, but then the node name should not have it. Please try
to find some more generic name (DT spec gives examples). Could be
display-controller, "hdr-engine", "isp".

date:

pip3 install dtschema --upgrade

Please check and re-submit.
