one question on the resets:
- in v1 you had three reset lines: RESET_PCIE_CTRL_A, RESET_PCIE_PHY,
RESET_PCIE_APB
- in v2 you only have the "phy" reset line.
is this because the other two are connected to the PCIe controller
(Documentation/devicetree/bindings/pci/amlogic,meson-pcie.txt) instead
of the PHY?


Regards
Martin
