Driver support for CSI2RX multi-stream was merged last cycle[0]. 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. Also enabling
DS90UB960 deserializer and DS90UB953 serializer drivers in the
arm64 defconfig.

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.

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.
CSI2RX connectivity on J784S4 and J742S2 is the same as that of J721S2,
hence the same overlay can be reused.

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.

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.

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 J784S4-EVM.

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.

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 serilaizer 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.
