[PATCH v3 09/13] dma: ti: k3-udma: Add DMA PSIL mappings for AM62P and J722S

Mon Feb 26 22:19:15 CET 2024
From: Vignesh Raghavendra <vigneshr at ti.com>
Add PSIL data for the AM62P and the J722S SoC family. The PSIL mapping
for the J722S is the same except for the extra instances of the CSI-RX.
So let's reuse the same file for both the AM62P and J722S.
