[v3] Add DSI display support for TI's Jacinto platforms

[PATCH v3 0/7] Add DSI display support for TI's Jacinto platforms

Posted by Jayesh Choudhary 2 months, 3 weeks ago

Hello All,

This series adds the dts support to enable DSI on 3 platforms for TI SoCs:
- J784S4-EVM
- J721S2-EVM
- AM68-SK

SN65DSI86 driver fix that was essential for display is now merged.

There is one more series relevant for driver that makes CDNS-DSI driver
work better:
https://lore.kernel.org/all/20250618-cdns-dsi-impro-v4-0-862c841dbe02@ideasonboard.com/

I have locally tested using kmstest utility on all 3 platforms.

Changelog v2->v3:
- Cosmetic changes like adding padding and new line before child nodes
- Using standard node name for regulator and bridge
- Remove "regulator-always-on" for dp-regulator in am68 and j721s2 board
- Remove interrupt-parent from dsi nodes

v2 patch link:
https://lore.kernel.org/all/20250624082619.324851-1-j-choudhary@ti.com/

Changelog v1->v2:
- [4/7]: Add gpio-line-names
- [6/7]: Remove unnecessary clocks from TIDSS

v1 patch link:

      commit: 11b9e4517bfa8edecbef0acfcad1bdca4f4a4192

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
