In term of structure or naming, they are not representative of real use-cases. This new test uses realistic dts and dtsa files with naming and structures tradidionally found in real cases. The dts describes the hardware of the base board. The hardware structure of the base board is the following: +--------------+ | 5V regulator +-------+ +--------------+ | | +----------------------+ | +----------------+ | SOC | | | Connector A | | | | | | | +-----------------+ | +-------+ 5v | | + i2c1 controller +---------------+ i2c bus | | +-----------------+ | +-------+ gpio 0 / irq 0 | | | | +---+ gpio 1 / irq 1 | | +------------------+ | | | +----------------+ | | gpio1 controller | | | | | | gpio #10 +------+ | | +------------------+ | | | | | | +---------------- -+ | | | | gpio2 controller | | | | | gpio #3 +----------+ | +------------------+ | +----------------------+ The connector 'Connector A' is the connector where the pluggable board can be connected to. It is described in the dts and related export symbols are set in order to be usable by the dtsa describing the pluggable board. The hardware structure of the pluggable board is the following: +---------------+ | EEPROM | | i2c addr 0x51 | | + +-------+ i2c | | +---------------+ | | +---------------+ | | Expander IO | +----------------+ | | i2c addr 0x23 | | Connector | | | | | | | +---+ Vcc1 | | 5v +---|---+---+ Vcc2 | | i2c bus +---+-------+ i2c | | gpio 0 / irq 0 +-----------+ irq | | gpio 1 / irq 1 +-----------+ reset | +----------------+ +---------------+ This structure is described in the addon dtsa. This addon dtsa is expected to be applied to the base device tree node describing the connector the pluggable board is connected to.
