… TC9563 PCIe switch node for PCIe0 Add a node for the TC9563 PCIe switch connected to PCIe0. The switch has three downstream ports.Two embedded Ethernet devices are present on one of the downstream ports. All the ports present in the node represent the downstream ports and embedded endpoints. Power to the TC9563 is supplied through two LDO regulators, which are on by default and are added as fixed regulators. TC9563 can be configured through I2C.

… second TC9563 PCIe switch node for PCIe1 Add a node for the second TC9563 PCIe switch on PCIe1, which is connected in cascade to the first TC9563 switch via the former's downstream port. Two embedded Ethernet devices are present on one of the downstream ports of this second switch as well. All the ports present in the node represent the downstream ports and embedded endpoints. The second TC9563 is powered up via the same LDO regulators as the first one, and these can be controlled via two GPIOs, which are already present as fixed regulators. This TC9563 can also be configured through I2C.
