The PCI controller on rk3399 requires the phy to correctly initialise the PCIE phy. Without phy initialisation the host and end-point controllers cannot be used. To prevent building an unusable PCIe driver on rk3399, enable the phy driver when the host or end-point driver is enabled. Signed-off-by: Punit Agrawal <punitagrawal@xxxxxxxxx> --- Hi, I've been caught out many times when booting off of PCI and finding that the kernel cannot find rootfs due to the missing phy driver. The patch should prevents this by fixing the Kconfig dependency enablement.
