Subject: [PATCH v2 14/18] media: dt-bindings: Add DT bindings for TI J721E CSI2RX driver
Date: Wed, 26 May 2021 20:53:04 +0530 [thread overview]
Message-ID: <20210526152308.16525-15-p.yadav@ti.com> (raw)
In-Reply-To: <20210526152308.16525-1-p.yadav@ti.com>
TI's J721E uses the Cadence CSI2RX and DPHY peripherals to facilitate
capture over a CSI-2 bus. The TI CSI2RX platform driver glues all the
parts together.
Signed-off-by: Pratyush Yadav <p.yadav@ti.com>
---
Changes in v2:
- Rename to ti,j721e-csi2rx.yaml
- Add an entry in MAINTAINERS.
- Add a description for the binding.
- Change compatible to ti,j721e-csi2rx to make it SoC specific.
- Remove description from dmas, reg, power-domains.
- Remove a limit of 2 from #address-cells and #size-cells.
- Fix add ^ to csi-bridge subnode regex.
- Make ranges mandatory.
- Add unit address in example.
- Add a reference to cdns,csi2rx in csi-bridge subnode.
- Expand the example to include the csi-bridge subnode as well.
- Re-order subject prefixes.

+title: TI J721E CSI2RX Wrapper Device Tree Bindings
+
+description: |
+ The TI J721E CSI2RX Wrapper is a wrapper around Cadence CSI2RX bridge that
+ enables sending captured frames to memory over PSI-L DMA. In the J721E
+ Technical Reference Manual (SPRUIL1B) it is referred to as "SHIM" under the
+ CSI_RX_IF section.
