Help text

Support the RP1 peripheral chip found on Raspberry Pi 5 board.

This device supports several sub-devices including e.g. Ethernet controller, USB controller, I2C, SPI and UART.

The driver is responsible for enabling the DT node once the PCIe endpoint has been configured, and handling interrupts.

This driver uses an overlay to load other drivers to support for RP1 internal sub-devices.
