There was a problem hiding this comment.
What you've written here is valid Device Tree, but it's not how we use it. Just "brcm.bcm2835" is preferred for a general purpose overlay like this.

Thanks for letting me know, I've fixed it.

Thanks for also adding the newline at the end. |
Add a new overlay for EDATEC IPC/EXP series industrial PC carrier boards. This overlay configures PCA9535 GPIO expanders on both i2c_csi_dsi and i2c_arm buses, with support for multiple board profiles (IPC2100, IPC2300, IPC3100, IPC3300, PLC2010, etc.) and optional expansion modules (exp8x8y, exp4x4y).

You're welcome. It's my pleasure. I'll keep monitoring the repair process until it's completely problem-free. |

Add a new device tree overlay
ed-ipcfor EDATEC IPC/EXP seriesindustrial PC carrier boards (based on Raspberry Pi Compute Module 4/5).
This overlay configures PCA9535 GPIO expanders on both i2c_csi_dsi
and i2c_arm buses, providing support for multiple board profiles and
optional expansion modules.
Supported board profiles
Usage example
dtoverlay=ed-ipc,ipc2600Additional parameters
addr— I2C address for primary PCA9535 (default 0x20)exp_addr— I2C address for secondary PCA9535 (default 0x27)exp8x8y— Enable 8-input/8-output expansion module (CM5)exp4x4y— Enable 4-input/4-output expansion module (CM5)All fragments use the dormant/override mechanism and have no effect
unless explicitly activated by a board profile parameter.
