How complex can the description of the hardware be in the manifest?
Could i describe an SPI to I2C converter? And then a few temperature
sensors, a fan controller, and a GPIO controller on that I2C bus? And
the GPIO controller is then used for LEDs and a push button? DT
overlays could describe that. Can the manifest?
