dmaengine: ti: k3-udma: Add support for J722S CSI BCDMA
Browse files Browse the repository at this point in the history
J722S CSI BCDMA is similar to J721S2 CSI BCDMA but there are slight
integration differences like different PSIL thread base ID which is
currently handled in the driver based on udma_of_match data. Add an
entry to support J722S CSIRX.
