CSI cameras are controlled using I2C. On J721S2 Common Processor Board,
this is routed to I2C-5, so enable the instance and the TCA6408
GPIO expander on the bus.

CSI cameras are controlled using I2C. On AM69 Starter Kit, this is routed
to I2C-1, so enable the instance, TCA9543 I2C switch and the TCA6408
GPIO expander on the bus. AM69 SK has the CSI2RX routed to a MIPI CSI
connector and to 22-pin RPi camera connector through an analog mux with
GPIO control, model that so that an overlay can control the mux state
according to connected cameras.

J721E SK has the CSI2RX routed to a MIPI CSI connector and to 15-pin
RPi camera connector through an analog mux with GPIO control, model that
so that an overlay can control the mux state according to connected
cameras. Also provide labels to the I2C mux bus instances so that a
generic overlay can be used across multiple platforms.

J721E has two CSI2RX capture subsystem featuring Cadence CSI2RX,
DPHY and TI's pixel grabbing wrapper. Add nodes for the same and
keep them disabled by default.

J721S2 has two CSI2RX capture subsystem featuring Cadence CSI2RX,
DPHY and TI's pixel grabbing wrapper. Add nodes for the same and
keep them disabled by default. J721S2 uses a dedicated BCDMA instance
for CSI-RX traffic, so enable that as well.

RPi v2 Camera (IMX219) is an 8MP camera that can be used with SK-AM69
through the 22-pin CSI-RX connector.
Same overlay can be used across AM68 SK, TDA4VM SK boards that have a
15/22-pin FFC connector. Also enable build testing and symbols for
all the three platforms.

You need to also add this "k3-am69-sk-csi2-imx219.dtb" to the list:
dtb- +=
below for it to actually get build tested.

Hi Vaishnav,
Thanks for the patch.

In that case, the overlay should be named something generic following
how it is done for SK-AM62* family of boards.
IMO, it would also make more sense to have separate overlays for CSI0
and CSI1 ports, unless there are no usecases to plug-in different
sensors on the board.
Even if that is done later, at least this overlay should be named in a
way to make it clear it enables 2x IMX219 on both CSI-RX ports, to avoid
confusion.
So, something like k3-<jacinto?>-sk-csi2-dual-imx219.dtso
This will leave room for a CSI1 only overlay to be called
k3-<>-sk-csi2-1-<sensor>.dtso

Andrew already pointed out that the base dtb should be added in the dtb-
+= entry at the end of this section.
Along with that, I think the overlay should be build-tested for each
base DTB (AM68, TDA4VM) it is applicable on. Same is already done for
the shared IMX219/OV5640 overlays between SK-AM62 and SK-AM62A.

Thank you for the review, for now I have renamed the overlay to the
first supported platform(j721e-sk), like AM62X family it is difficult
to pick a common name for these platforms (TDA4VM SK, AM68 SK, AM69 SK),
also jacinto-*.dtso gives the wrong impression that these might work
with the EVMs, so for now I have picked the name to follow the first
supported platfor j721e-sk and clarified in comments and commit message
that this can be reused with other platforms.
