arm64: dts: k3-j721e: Add BBAI64 CSI1 IMX219 camera overlay #92
Conversation
Add device tree overlay for IMX219 camera on CSI1 interface of BeagleBone AI-64 board. Enables GPIO0_101 (pin V25) as camera enable signal. The overlay configures: - Sony IMX219 camera sensor on main_i2c6 (I2C1) - Fixed 24MHz clock for camera - Enable GPIO using existing csi1_gpio_pins_default pinmux - CSI2 RX bridge and DPHY1 configuration - 2-lane MIPI CSI-2 interface at 456 MHz link frequency Fixes: beagleboard#66 Signed-off-by: immortal71 <newaashish190@gmail.com>

Pull request overview
This PR adds a device tree overlay for the Sony IMX219 camera sensor (Raspberry Pi Camera V2.1) on the CSI1 interface of the BeagleBone AI-64 board. The overlay configures the camera sensor on I2C1 (main_i2c6), provides a 24MHz fixed clock, configures GPIO0_101 as the camera enable signal, and sets up the 2-lane MIPI CSI-2 interface with appropriate bridging through the Cadence CSI2RX and TI wrapper.
Key changes:
- Device tree overlay for IMX219 camera on CSI1 connector
- GPIO enable signal configuration using GPIO0_101 (pin V25)
- 2-lane CSI-2 configuration with 456 MHz link frequency

The SPDX license identifier should be GPL-2.0-only OR MIT to match all other BeagleBone AI-64 overlays in this directory (e.g., k3-j721e-beagleboneai64-pwm-epwm0-p8_13.dtso, k3-j721e-beagleboneai64-BBORG_MOTOR.dtso). This ensures license consistency across the overlay collection.

I don't have BeagleBone AI-64 hardware with IMX219 camera to test this configuration. The overlay follows the pattern from other camera overlays in the tree and uses the GPIO pin (V25/GPIO0_101) specified in the issue. Hardware testing by maintainers would be appreciated to confirm:
Fixes: #66
