[gregkh]

This is a note to let you know that I've just added the patch titled

    staging: mt7621-pci-phy: dt-bindings: add bindings for Mediatek

to my staging git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-next branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will also be merged in the next major kernel release

+Mediatek Mt7621 PCIe PHY
+
+Required properties:
+- compatible: must be "mediatek,mt7621-pci-phy"
+- reg: base address and length of the PCIe PHY block
+- #address-cells: must be 1
+- #size-cells: must be 0
+
+Each PCIe PHY should be represented by a child node
+
+Required properties For the child node:
+- reg: the PHY ID
+0 - PCIe RC 0
+1 - PCIe RC 1
+- #phy-cells: must be 0
+
+Example:
+	pcie0_phy: pcie-phy@1a149000 {
+		compatible = "mediatek,mt7621-pci-phy";
+		reg = <0x1a149000 0x0700>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		pcie0_port: pcie-phy@0 {
+			reg = <0>;
+			#phy-cells = <0>;
+		};
+
+		pcie1_port: pcie-phy@1 {
+			reg = <1>;
+			#phy-cells = <0>;
+		};
+	};
+
+	pcie1_phy: pcie-phy@1a14a000 {

+		reg = <0x1a14a000 0x0700>;
+		#address-cells = <1>;
