The commit msg needs to answer "why". The DT is an ABI. You can't just replace property(ies) with a new property. There's exceptions if there are no platforms in use or similar. This binding needs to be converted to dtschema before adding to it. > > Signed-off-by: Jenishkumar Maheshbhai Patel <jpatel2@marvell.com> > --- > Documentation/devicetree/bindings/pci/pci-armada8k.txt | 10 ++++------ > 1 file changed, 4 insertions(+), 6 deletions(-) > > diff --git a/Documentation/devicetree/bindings/pci/pci-armada8k.txt b/Documentation/devicetree/bindings/pci/pci-armada8k.txt > index a177b971a9a0..a9a71d77b261 100644 > --- a/Documentation/devicetree/bindings/pci/pci-armada8k.txt > +++ b/Documentation/devicetree/bindings/pci/pci-armada8k.txt > @@ -24,10 +24,9 @@ Optional properties: > - phy-names: names of the PHYs corresponding to the number of lanes. > Must be "cp0-pcie0-x4-lane0-phy", "cp0-pcie0-x4-lane1-phy" for > 2 PHYs. > -- marvell,system-controller: address of system controller needed > - in order to reset MAC used by link-down handle > -- marvell,mac-reset-bit-mask: MAC reset bit of system controller > - needed in order to reset MAC used by link-down handle > +- resets: phandle reset controller with int reset controller bit. > + needed in order to reset MAC used by link-down handle. > + > > Example: > > @@ -49,6 +48,5 @@ Example: > interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>; > num-lanes = <1>; > clocks = <&cpm_syscon0 1 13>; > - marvell,system-controller = <&CP11X_LABEL(syscon0)>; > - marvell,mac-reset-bit-mask = <CP11X_PCIEx_MAC_RESET_BIT_MASK(1)>; > + resets = <&CP11X_LABEL(pcie_mac_reset) CP11X_PCIEx_MAC_RESET_BIT(0)>; > }; > -- > 2.25.1 >
