v3 cover drm/panel: Add Anbernic RG353V-V2 Panel

From: Chris Morgan <[email protected]>

Add the NewVision NV3051D panel as found on the second revision of the RG353V. The underlying LCD panel itself is unknown (ST7703 is the controller IC).

Changes from V2:
- Rebased patch series (to address removal of dsi_dcs_write_seq custom macro).

Changes from V1:
- Split redefinition of CMD_UNKNOWN_C6 into separate patch.

PATCH v3 1/3 dt-bindings: panel: Add Anbernic RG353V-V2 panel compatible

From: Chris Morgan <[email protected]>

The Anbernic RG353V-V2 panel is a 3.5 inch 640x480 MIPI-DSI LCD panel. It's based on the ST7703 LCD controller just like rocktech,jh057n00900. It's used in a 2nd revision of the Anbernic RG353V handheld gaming device. Like the first revision of the RG353V the control chip is known but the panel itself is unknown, so name it for the device.

PATCH v3 3/3 drm/panel: st7703: Add Anbernic RG353V-V2 Panel Support

In reply to Chris Morgan

From: Chris Morgan <[email protected]>

The Anbernic RG353V-V2 is a 5 inch panel used in a new revision of the Anbernic RG353V handheld gaming device. Add support for it.

Unfortunately it appears this controller is not able to support 120hz or 100hz mode like the first revision panel.

Hi Chris,
could you check if these two modifications by Frank of the init sequence

https://lore.kernel.org/dri-devel/[email protected]/
https://lore.kernel.org/dri-devel/[email protected]/

work for your panel too?

Re: [PATCH V3 1/3] dt-bindings: panel: Add Anbernic RG353V-V2 panel compatible

Hi Chris,
hi Guido,

Hi Chris,
could you check if these two modifications by Frank of the init sequence

   https://lore.kernel.org/dri-devel/[email protected]/
   https://lore.kernel.org/dri-devel/[email protected]/

work for your panel too?

I saw that Chris' patchset got accepted into drm-next, and I'm glad that more panels will therefore work out of the box. But: Did anyone check if the modifications I submitted in February and that Guido referenced above work with the new panel?

Thanks,
Frank

The Anbernic RG353V-V2 panel is a 3.5 inch 640x480 MIPI-DSI LCD panel. It's based on the ST7703 LCD controller just like rocktech,jh057n00900. It's used in a 2nd revision of the Anbernic RG353V handheld gaming device. Like the first revision of the RG353V the control chip is known but the panel itself is unknown, so name it for the device.

The Anbernic RG353V-V2 is a 5 inch panel used in a new revision of the Anbernic RG353V handheld gaming device. Add support for it.

Unfortunately it appears this controller is not able to support 120hz or 100hz mode like the first revision panel.

Hi Chris,
could you check if these two modifications by Frank of the init sequence

work for your panel too?

I saw that Chris' patchset got accepted into drm-next, and I'm glad that more panels will therefore work out of the box. But: Did anyone check if the modifications I submitted in February and that Guido referenced above work with the new panel?

Chris, could you please check that the new rg353v-panel-v2 works with the changes I proposed.

Guido, could you please check that the jh057n00900 panel works with the changes I proposed.

Without these patches the XBD599 panel does not work reliably, so in the long run it's desirable to include them in mainline. Currently, the only user of the XBD599 panel that I'm aware of is the pinephone. Therefore, all distributions supporting the pinephone rely on out-of-tree patches to support the XDB599 panel.

I'd appreciate if we could rectify this situation.

Thank you both for your support,
Frank

The Anbernic RG353V-V2 panel is a 3.5 inch 640x480 MIPI-DSI LCD panel. It's based on the ST7703 LCD controller just like rocktech,jh057n00900. It's used in a 2nd revision of the Anbernic RG353V handheld gaming device. Like the first revision of the RG353V the control chip is known but the panel itself is unknown, so name it for the device.

A later revision of the datasheet for the ST7703 refers to this command as "SETECO".

The Anbernic RG353V-V2 is a 5 inch panel used in a new revision of the Anbernic RG353V handheld gaming device. Add support for it.

Unfortunately it appears this controller is not able to support 120hz or 100hz mode like the first revision panel.
