Subject: [PATCH v2 1/2] misc: lan966x_pci: Fix dtc warns 'missing or empty reg/ranges property'
dtc generates the following warnings when building the LAN966x device
tree overlay (lan966x_pci.dtso):
Warning (simple_bus_reg): /fragment@..._overlay__/pci-ep-bus@...pu_clk: missing or empty reg/ranges property
Warning (simple_bus_reg): /fragment@..._overlay__/pci-ep-bus@...dr_clk: missing or empty reg/ranges property
Warning (simple_bus_reg): /fragment@..._overlay__/pci-ep-bus@...ys_clk: missing or empty reg/ranges property
Indeed, related nodes are under the pci-ep-bus (simple-bus) which is not
correct.
Put them outside this node.
Reported-by: Stephen Rothwell <sfr@...b.auug.org.au>
Closes: https://lore.kernel.org/all/20241025110919.64b1cffb@canb.auug.org.au/
Fixes: 185686beb464 ("misc: Add support for LAN966x PCI device")
