Subject: [PATCH v3 0/2] Add support for J722S CSI BCDMA

This series adds support for CSI Block Copy DMA (BCDMA) instance on J722S,
the BCDMA instance is similar to other CSI BCDMA found in rest of TI
devices like J721S2, AM62A. It supports both RX (CSI2RX) and TX (CSITX)
channels and is identical to J721S2 CSIRX BCDMA but has slight integration
difference in the PSIL base thread ID which is currently handled in the 
k3-udma driver from the match_data, introduce a new compatible to support
J722S BCDMA.

Changelog:
  V2->V3:
    * Added missing compatible entry missed in v2.
    * Address Krzysztof's review comments to not wrap commit
    message too early.

  V1->V2:
    * Address review from Conor to add new J722S compatible
    * J722S BCDMA is more similar to J721S2 in terms of RX/TX support,
    add an entry alongside J721S2 instead of modifying AM62A.

V2: https://lore.kernel.org/all/20241126125158.37744-1-vaishnav.a@ti.com/

CSI2RX capture test results on J722S EVM with 4 x IMX219:
