Hi all, this patch series implement MIPI rx DPI feature. Please help to review.
This is the v1 version, any mistakes, please let me know, I'll fix it in the next series.
Change history: v1: initial MIPI rx DPI feature support
Xin Ji (2): dt-bindings: drm/bridge: anx7625: add DPI flag and swing setting drm/bridge: anx7625: add MIPI DPI input feature support

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.

This sounds similar to the bus-type property defined in Documentation/devicetree/bindings/media/video-interfaces.txt (which is getting converted to YAML, Rob has posted a patch series, I expect it to land in v5.13). I think it would make sense to extend bus-type to support DSI, and use that property.

Hi Laurent Pinchart, as the different vendor has the different PCB layout, it effects DP CTS test result, so they may need config DP tx Swing register to adjust signal swing(the default swing setting is not satisfy for every platform). If we move the config code to driver file, it must define swing register setting for each vendor, so the DT is the best way. Do you have any idea for it if you don't agree to add in DT.

This sounds similar to the bus-type property defined in Documentation/devicetree/bindings/media/video-interfaces.txt (which is getting converted to YAML, Rob has posted a patch series, I expect it to land in v5.13). I think it would make sense to extend bus-type to support DSI, and use that property.
Sorry, I didn't found any define for DPI or DSI flag in Rob's patches. Do you mean I just remove this flag define and call a special function to read the port's type(DSI or DPI)?

If it depends on the PCB layout then it should indeed be in DT. What I wonder is if there would be a better way to specify the data than register values. The ANX7625 datasheet isn't public, so there's effectively no way for someone to write a device tree compliant with this binding only with the information contained here. Reviewing the bindings is equally difficult. It would be best if this property instead contained information that could be documented clearly.

video-interfaces.yaml has initially been written for cameras, so it doesn't support DSI. I think it would make sense to extend the bus-type property with a DSI type, and use it here instead of a vendor-specific property.
Alternatively, I'm wondering if this isn't information we could query at runtime. DRM bridges and panels have a type, so we could look at the next bridge or panel to find the type of the connected device instead of specifying it in DT.

Hi Laurent Pinchart, the swing register setting is optional. Basically, no need to care about it if customer PCB layout match our chip requirement. The property define just in case. So far, we just found one customer encountered DP tx swing issue. As the datasheet swing register adjusting algorithm has a little complex, we will help customer to adjust the DP tx swing case by case.

At anx7625 driver probe stage, for the DSI, driver needs call some special interface to attach to DSI interface. For the DPI port, there is no such limitation, so we need to know what kind of MIPI signal type at driver initial stage. Maybe we can keep this flag, if the future has defined DSI, I'll submit new patch to remove this flag.
Thanks, Xin
