[PATCH v2 0/9] arm64: dts: ti: Enable CSI cameras for AM62 family

[PATCH v2 0/9] arm64: dts: ti: Enable CSI cameras for AM62 family

[Jai Luthra]

This series enables CSI camera support on BeaglePlay, SK-AM62 and
SK-AM62A, now that the dt-bindings and driver support for CSI-RX related
IPs is merged in v6.7-rc1.

Along with the device tree nodes for CSI-RX, add new DT overlays for
different camera modules like RPiv2 (IMX219) or PCam5C (OV5640).

Signed-off-by: Jai Luthra <j-luthra@ti.com>
---
Changes in v2:
- Follow Andrew's comments to avoid creating combined DTBs with overlays
  applied, instead adding them with "dtb- +=" to optionally test that
  they apply cleanly with OF_ALL_DTBS=y config.
- [New Patch] Cleanup existing combined DTBs to also do the same as above
- Pick Martyn's Tested-By tag for SK-AM62
- Link to v1: https://lore.kernel.org/r/20231115-csi_dts-v1-0-99fc535b2bde@ti.com

[PATCH v2 1/9] arm64: defconfig: Enable AM62 CSI2RX

[Jai Luthra]

AM62 and other K3 based SoCs use Cadence DPHY and CSI-RX bridge drivers,
along with a DMA wrapper CSI IP for the camera pipeline.

[PATCH v2 3/9] arm64: dts: ti: Enable CSI-RX on AM62A

[Jai Luthra]

Add nodes for Cadence DPHY, CSI2RX and TI's pixel-grabbing wrapper.
AM62A uses a dedicated BCDMA instance for CSI-RX traffic, so enable that
as well.

[PATCH v2 4/9] arm64: dts: ti: k3-am625-beagleplay: Add overlays for OV5640

[Jai Luthra]

Three different OV5640 modules are supported using the FFC connector on
BeaglePlay:
- Digilent PCam 5C
- ALINX AN5641
- TEVI-OV5640-*-RPI

The Digilent and ALINX modules supply a 12Mhz XCLK to the sensor, while
the TEVI module supplies a 24Mhz XCLK, thus requiring a separate
overlay.

[PATCH v2 5/9] arm64: dts: ti: k3-am62x-sk: Enable camera peripherals

[Jai Luthra]

CSI cameras are controlled using I2C, on SK-AM62 and derivative boards
this is routed to I2C-2, so enable that bus. Also enable the nodes for
CSI-RX and DPHY-RX IPs.

Specific sensor connected to this bus will be described in the DT
overlay for each sensor.

[PATCH v2 6/9] arm64: dts: ti: k3-am62x: Add overlays for OV5640

[Jai Luthra]

Three different OV5640 modules are supported using the 15-pin FFC
connector on SK-AM62:
- Digilent PCam 5C
- ALINX AN5641
- TEVI-OV5640-*-RPI

The Digilent and ALINX modules supply a 12Mhz XCLK to the sensor, while
the TEVI module supplies a 24Mhz XCLK, thus requiring a separate
overlay.

These overlays can be used on other boards of the SK-AM62* family that
have a 15/22-pin FFC connector, so we name the overlays with the prefix
k3-am62x-.

[PATCH v2 7/9] arm64: dts: ti: k3-am62a7-sk: Enable camera peripherals

[Jai Luthra]

Enable the nodes for CSI-RX, DPHY-RX and I2C-2 as it is used to control
CSI based sensors. Also enable IO-EXP-2 as it controls the mux between
different CSI-2 connectors.

[PATCH v2 8/9] arm64: dts: ti: k3-am62x: Add overlay for IMX219

[Jai Luthra]

RPi v2 Camera (IMX219) is an 8MP camera that can be used with SK-AM62A
through the 22-pin CSI-RX connector.

Same overlay can be used across SK-AM62* boards that have a 15/22-pin
FFC connector, so we name it with the k3-am62x- prefix.

[PATCH v2 9/9] arm64: dts: ti: Use OF_ALL_DTBS for combined blobs

[Jai Luthra]

Combined dtb builds are only useful for making sure that the overlay
applies cleanly on the base dtb.

So we move all such combined blobs under a `dtb- +=` section that is
only built when OF_ALL_DTBS config is enabled.

Too bad the build test check doesn't add this for us, might be time
to just make this default, I see broadcom/Makefile has:

DTC_FLAGS := -@

Well we can look into that later, this patch LGTM,

Why do this in the common file? These should go in the overlays
that actually make use of these nodes, same as you did for BeaglePlay
in patch [4/9].

Hi Andrew,

Thanks for the comments.

Makes sense for the csi2rx nodes, will move it to the overlay in v3.

For the i2c node (and also gpio expander on sk-am62a) I think it is 
better to enable them in the base DTB here, as it helps in 
detecting/debugging new sensors using userspace utilities like 
i2c-detect without actually having a functional overlay.
