[PATCH v2 0/7] rockchip: rk3568: Fix use of PCIe bifurcation

[Jonas Karlman]

Hi Kever,

It would be nice to get some feedback and plans for this and the
following series :-)

rockchip: rk3568: Fix use of PCIe bifurcation (this series)
https://patchwork.ozlabs.org/cover/1816140/

rockchip: rk3568-nanopi-r5: Add missing PCIe options
https://patchwork.ozlabs.org/cover/1816147/

rockchip: Port IO-domain driver for RK3568 from linux
https://patchwork.ozlabs.org/cover/1823769/

I also plan to send a v2 with small update based on the little feedback
I got on the following:

rockchip: Add GMAC support for RK3568 and RK3588
https://patchwork.ozlabs.org/cover/1817469/

Regards,
Jonas
