Support for multi-stream in j721e-csi2rx.c driver was merged recently [0].
Therefore this series adds the corresponding device tree support.
Patch 1 is a cleanup fixing indentation in the existing CSI2RX nodes.
The next few patches i.e. (Patch 2 to Patch 6) add the additional DMA
channels required for CSI2RX multi-stream capture.
Multi-stream capture uses a SERDES pair based on the FPD-Link or
V3Link protocol. The serializer takes the input from a camera sensor
and converts it to the FPD-Link standard, while the deserializer
aggregates streams from multiple serializers and sends them over the
CSI-2 RX interface. Each CSI2RX instance therefore indirectly receives
input from multiple sensors.
The remaining patches add overlays for various deserializer boards,
and for the UB953 serializer with the IMX219 sensor. Finally, patch 18
enables the DS90UB960 deserializer and DS90UB953 serializer drivers
in the arm64 defconfig.
Changes in v3:
- Rename fixed-clock nodes to the generic clock-<frequency> form (Krzysztof)
- Also rename fixed-clock labels to lowercase
- Reword defconfig commit message to explicitly mention the target vendor
and upstream boards using these drivers (Krzysztof)
- Override CSI2RX ports using &csiN_port0 labels instead of the full
&cdns_csi2rxN node path, and drop duplicated properties (Krzysztof)
- Drop underscores from regulator node names to follow upstream dts style (Krzysztof)
- Fix minor DTS coding style issues in overlays (Sashiko and Krzysztof)
- Use GPL-2.0-only OR MIT license in all overlays for consistency
- Update copyright year to 2026 in all overlays (Udit)
- Use board names such as J721E-EVM and J721S2-EVM instead of J721E, J721S2
in commit messages (Udit)
- Collect Reviewed-by tags from Udit (Patches 01, 17) and Rishikesh
- Rebase on next-20260918

From: Vaishnav Achath <vaishnav.a@ti.com>
Fusion application daughter board [1] can be used to connect multiple
FPDLink-III based sensors to TI EVMs. The board has two DS90UB960
deserializers, each of which aggregates input from up to 4x FPDLink-III
sensors. Up to 8x sensors can simultaneously stream over the two CSI RX
ports on J721E-EVM.

Changes in v3:
- Rename fixed-clock node to the generic clock-<frequency> form
(Krzysztof)
- Also rename fixed-clock label to lowercase
- Override CSI2RX port using &csi0_port0 label instead of the full
&cdns_csi2rx0 node path, and drop duplicated properties (Krzysztof)
- Use GPL-2.0-only OR MIT license for consistency
- Update copyright year to 2026 (Udit)
- Use board name J721E-EVM instead of J721E in commit message (Udit)

From: Vaishnav Achath <vaishnav.a@ti.com>
Fusion application daughter board [1] can be used to connect multiple
FPDLink-III based sensors to TI EVMs. The board has two DS90UB960
deserializers, each of which aggregates input from up to 4x FPDLink-III
sensors. Up to 8x sensors can simultaneously stream over the two CSI RX
ports on J721S2-EVM.
CSI2RX connectivity on J784S4-EVM and J742S2-EVM is the same as that of
J721S2-EVM, hence the same overlay can be reused.

Changes in v3:
- Rename fixed-clock node to the generic clock-<frequency> form
(Krzysztof)
- Also rename fixed-clock label to lowercase
- Override CSI2RX port using &csi0_port0 label instead of the full
&cdns_csi2rx0 node path, and drop duplicated properties (Krzysztof)
- Use GPL-2.0-only OR MIT license for consistency
- Update copyright year to 2026 (Udit)
- Use board name J721S2-EVM instead of J721S2 in commit message (Udit)

From: Vaishnav Achath <vaishnav.a@ti.com>
Fusion application daughter board [1] can be used to connect multiple
FPDLink-III based sensors to TI EVMs. The board has two DS90UB960
deserializers, each of which aggregates input from up to 4x FPDLink-III
sensors. Up to 8x sensors can simultaneously stream over the two CSI RX
ports on J722S-EVM.

Changes in v3:
- Rename fixed-clock node to the generic clock-<frequency> form
(Krzysztof)
- Also rename fixed-clock label to lowercase
- Override CSI2RX ports using &csiN_port0 labels instead of the full
&cdns_csi2rxN node path, and drop duplicated properties (Krzysztof)
- Use GPL-2.0-only OR MIT license for consistency
- Update copyright year to 2026 (Udit)

From: Vaishnav Achath <vaishnav.a@ti.com>
Arducam's V3Link mini fusion board [1] has a single DS90UB960
deserializer which can aggregate input from up to 4x V3Link (and
FPD-Link III) based cameras over a single 22-pin FFC (4-lane) CSI-2
connector. Add an overlay supporting two such boards, each connected to
one of the two CSI RX inputs on AM68-SK.
The same overlay can be reused on AM69-SK and J721E-SK.

From: Vaishnav Achath <vaishnav.a@ti.com>
Arducam's V3Link mini fusion board [1] has a single DS90UB960
deserializer which can aggregate input from up to 4x V3Link (and
FPD-Link III) based cameras over a single 22-pin FFC (4-lane) CSI-2
connector. Add an overlay supporting two such boards, each connected to
one of the two CSI RX inputs on J722S-EVM.

Changes in v3:
- Rename fixed-clock node to the generic clock-<frequency> form
(Krzysztof)
- Also rename fixed-clock label to lowercase
- Override CSI2RX ports using &csiN_port0 labels instead of the full
&cdns_csi2rxN node path, and drop duplicated properties (Krzysztof)
- Fix minor DTS coding style issues (Sashiko)
- Use GPL-2.0-only OR MIT license for consistency
- Update copyright year to 2026 (Udit)

J7EXPA01EVM Fusion2 serial capture expansion board features 3 UB9702
deserializers, each capable of aggregating data from up to 4x cameras
over the FPDLink-IV interface. Add support for the same on J722S-EVM.

DS90UB954-Q1EVM consists of a DS90UB954 deserializer which aggregates
data from up to 2x cameras over the FPDLink-III interface, and can be
used to connect FPDLink-III based sensors to TI EVMs.
Add an overlay to support it on J721S2-EVM. CSI2RX connectivity on
J784S4-EVM and J742S2-EVM is the same as that of J721S2-EVM, hence the
same overlay can be reused.

DS90UB954-Q1EVM consists of a DS90UB954 deserializer which aggregates
data from up to 2x cameras over the FPDLink-III interface, and can be
used to connect FPDLink-III based sensors to TI EVMs.
Add an overlay to support it on J721E-EVM.

Changes in v3:
- Rename fixed-clock node to the generic clock-<frequency> form
(Krzysztof)
- Also rename fixed-clock label to lowercase
- Override CSI2RX port using &csi0_port0 label instead of the full
&cdns_csi2rx0 node path, and drop duplicated properties (Krzysztof)
- Update copyright year to 2026 (Udit)

From: Jianzhong Xu <xuj@ti.com>
Arducam V3Link camera solution is shipped with an UB953 serializer
and an IMX219 sensor [1]. Add an overlay for interfacing the UB953
serializer and IMX219 sensor with the RX0 port on the UB960 deserializer.
This overlay can be used to interface an IMX219 sensor on any platform
that supports the V3Link fusion board.

Texas Instruments DS90UB960 deserializer and DS90UB953 serializer
enable capturing from multiple camera sensors on Texas Instruments
K3 platforms.
Some of the upstream-supported platforms where this deserializer and
serializer can be used are the Texas Instruments J784S4-EVM [1]
(k3-j784s4-evm.dts) and J722S-EVM [2] (k3-j722s-evm.dts).
Hence enable building Texas Instruments DS90UB960 deserializer and
DS90UB953 serializer drivers as modules.

Changes in v3:
- Reword commit message to explicitly mention the target vendor and
upstream boards using these drivers (Krzysztof)
Note: Board names in the tree are lowercase, so please grep case
insensitively, e.g. `git grep -i J784S4-EVM` on next-20260918 gives
