@ -3,45 +3,19 @@ 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
- #phy-cells: must be <1> for pcie0_phy and for pcie1_phy.
Example:
pcie0_phy: pcie-phy@1a149000 {
pcie0_phy: pcie-phy@1e149000 {
compatible = "mediatek,mt7621-pci-phy";
