This patch enables the CONFIG_I2C_BRCMSTB option in vc4graphics.cfg to ensure proper support for the `brcm,bcm2711-hdmi-i2c` device node. Without this configuration, the I2C bus associated with HDMI on Broadcom BCM2711-based systems may fail to probe, causing issues with HDMI communication and display initialization. Additionally, this resolves potential deferred probe issues observed in the kernel logs, ensuring the correct initialization of the HDMI I2C bus.

Description
This is the general hardware specific BSP overlay for the RaspberryPi device.
More information can be found at: http://www.raspberrypi.org/ (Official Site)
The core BSP part of meta-raspberrypi should work with different OpenEmbedded/Yocto distributions and layer stacks, such as:
- Distro-less (only with OE-Core).
- Yoe Disto (Video and Camera Products).
- Yocto/Poky (main focus of testing).
Yocto Project Compatible Layer
This layer is officially approved as part of the Yocto Project Compatible Layers Program. You can find details of that on the official Yocto Project
website.
Dependencies
This layer depends on:
- URI: git://git.yoctoproject.org/poky
- branch: master
- revision: HEAD
Quick Start
- source poky/oe-init-build-env rpi-build
- Add this layer to bblayers.conf and the dependencies above
- Set MACHINE in local.conf to one of the supported boards
- bitbake core-image-base
- Use bmaptool to copy the generated .wic.bz2 file to the SD card
- Boot your RPI
Quick Start with kas
- Install kas build tool from PyPi (sudo pip3 install kas)
- kas build meta-raspberrypi/kas-poky-rpi.yml
- Use bmaptool to copy the generated .wic.bz2 file to the SD card
- Boot your RPI
To adjust the build configuration with specific options (I2C, SPI, ...), simply add a section as follows:
local_conf_header:
rpi-specific: |
ENABLE_I2C = "1"
RPI_EXTRA_CONFIG = "dtoverlay=disable-bt"
To configure the machine, you have to update the machine variable.
And the same for the distro.
