| |
Konstantin,
In commit 5c0ee54723f3 ("arm64: dts: add support for Marvell cn9130-crb platform") which added support for the cn9130-crb where are the PCI RESET# and CLKREQ# pins configured and specified?
As PCIE_PERST# is connected to CP_MPP[52] on the board I expected to either see something like: cp0_pci_pins: cp0-pci-pins-0 { marvell,pins = "mpp52"; marvell,function = "pci"; };
or: &cp0_pcie0 { gpios-reset = <&cp0_gpio2 20 GPIO_ACTIVE_LOW>; };
I don't see any support in the PCIe driver (marvell,armada8k-pcie, snps,dw-pcie) that support gpios-reset.
I'm working on support for another cn9130 board and am unclear how to configure the pinctrl for PERST# as well as CLKREQ3. Any pointers would be greatly appreciated.
Best Regards,
Tim
