dmaengine: ti: k3-udma: Add PSIL threads for AM62P and J722S
Add PSIL thread information and enable UDMA support for AM62P and J722S SoC. J722S SoC family is a superset of AM62P, thus common PSIL thread ID map is reused for both devices. For those interested, more details about the SoC can be found in the Technical Reference Manual here: AM62P - https://www.ti.com/lit/pdf/spruj83 J722S - https://www.ti.com/lit/zip/sprujb3 Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Signed-off-by: Bryan Brattlof <bb@ti.com> Signed-off-by: Vaishnav Achath <vaishnav.a@ti.com> Reviewed-by: Jai Luthra <j-luthra@ti.com> Link: https://lore.kernel.org/r/20231213081318.26203-1-vaishnav.a@ti.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
