1) Tested rk3568 NanpPi-R5s with Samsung 980 NVMe using linux 6.4.7 device tree. MMC boot media.
2) Tested rk3588 ROCK 5B with Samsung 980 and Samsung 970 EVO Plus NVMe using Sebastian Reichel's rk3588 device tree: https://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-misc.git/log/?h=rk... Both MMC and SPI boot media were tested.

This series add support for use of PCIe bifurcation on RK3568, and as a bonus support for the RK3588 PHY is also included. With PCIe bifurcation supported it is possible to enable PCIe on more RK3568 boards, e.g. on NanoPi R5C and NanoPi R5S. This series only include fixing the mini PCIe slot on Radxa E25.
Most parts of this series was imported almost 1:1 from mainline linux.
Patch 1 fixes configuration of number of lanes in pcie_dw_rockchip. Patch 2-3 refactor the snps-pcie3 phy driver. Patch 4 add bifurcation support for RK3568. Patch 5 add support for RK3588 to snps-pcie3 driver. Patch 6 fixes use of pcie2x1l0 on ROCK 5B. Patch 7 enables the mini PCIe slot on Radxa E25.
Changes in v2:
- Fix use of signal from comb PHY on RK3588
- Add fixes tag
The RK3588 PHY part was tested on a ROCK 5B together with device tree files picked from Sebastian Reichel's rk3588 branch at [1].
Patches in this series is also aviliable at [2].
