[PATCH v2 0/2] RK3588 PCIe3 support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



This adds PCIe v3 support for RK3588. The series depends on the PCIe
v2 series [0], since the the same binding is used. It has been tested
on Rockchip EVB1 and Radxa Rock 5B.

Note, that the PCIe3 PHY driver is currently missing bifurcation
support for RK3588. Thus after this series only PCIe3x4 is usable
(in aggregated x4 mode) without adding support for the PHY's
"rockchip,pcie30-phymode" DT property, which allows configuring
how the lanes are distributed. Aggregated 3x4 mode seems to be the
most common configuration. Both EVB1 and Rock 5B use it, so I
cannot test anything else anyways.
