[PATCH v3 0/2] PCI: xilinx-nwl: Add clock handling

[Michal Simek]

Hi,

this small series add support for enabling PCIe reference clock by driver.

Thanks,
Michal

Changes in v3:
- use PCIe instead of pcie
- add stable cc
- update commit message - reported by Krzysztof

Changes in v2:
- new patch in this series because I found that it has never been sent
- Update commit message - reported by Krzysztof
- Check return value from clk_prepare_enable() - reported by Krzysztof

[PATCH v3 1/2] dt-bindings: pci: xilinx-nwl: Document optional clock property

[Michal Simek]

Clock property hasn't been documented in binding document but it is used
for quite a long time where clock was specified by commit 9c8a47b484ed
("arm64: dts: xilinx: Add the clock nodes for zynqmp").

Bharat: Can you please start to work on converting it to yaml?
