dt-bindings: dma: ti: k3-bcdma: Add J722S CSI BCDMA

2024-12-24T10:02:21Z

J722S CSI BCDMA is similar to J721S2 CSI BCDMA and supports both RX and TX channels but has a different PSIL thread base ID which is currently handled in k3-udma driver. Add an entry for J722S CSIRX BCDMA. Signed-off-by: Vaishnav Achath Reviewed-by: Rob Herring (Arm) Link: https://lore.kernel.org/r/20241127101627.617537-2-vaishnav.a@ti.com Signed-off-by: Vinod Koul

dt-bindings: dma: ti: k3-udma: Describe cfg register regions

2023-11-24T08:42:37Z

Unified DMA (UDMA) module on K3 SoCs have TX and RX channel cfg and RX flow cfg register regions which are usually configured by a Device Management firmware. But certain entities such as bootloader (like U-Boot) may have to access them directly. Describe this region in the binding documentation for completeness of module description. Keep the binding compatible with existing DTS files by requiring first four regions to be present at least.

dt-bindings: ti,k3: Use common ti,k3-sci-common.yaml schema

2023-02-03T00:05:57Z

Instead of redefining the 'ti,sci' and 'ti,sci-dev-id' properties multiple times, reference the common schema where they are defined. Most cases using these properties already do this, just udma and ringacc need to be fixed.

dt-bindings: dma: ti: k3-bcdma: Add bindings for BCDMA CSI RX

2022-12-28T06:37:11Z

AM62A SoC has a dedicated BCDMA that serves Camera Serial Interface (CSI) IP. Add new compatible for the same. Unlike system BCDMA, this instance only has RX DMA channels and lack TX or block copy channel. Thus make those properties optional. Additionally CSI RX has independent power domain, add the binding for the same.
