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

Hello All,

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

This series *depends* upon a couple of driver series[0][1]and a config
patch[2] that enables CDNS_DSI and CDNS_DPHY.

[0]: <https://lore.kernel.org/all/20250402-cdns-dsi-impro-v2-0-4a093eaa5e27@ideasonboard.com/>
This series adds cdns-dsi-core fixes

[1]: <https://lore.kernel.org/all/20250411092307.238398-1-j-choudhary@ti.com/>
This patch adds the necessary DSI flags that are used in cdns-dsi-core
driver which are propagated from sn65dsi86 bridge.

[2]: <https://lore.kernel.org/all/20250411095043.272488-1-j-choudhary@ti.com/>
This patch enables the required configs for DSI.

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

NOTE: For higher resolutions, we need bigger CMA region.
But for validation, the default value is enough.
I am posting another series to add CMA region to Jacinto platforms
similar to Sitara family soon:
