Moreover, + for the i.MX platform, there is also a NETCMIX block for link configuration, + such as MII protocol, PCS protocol, etc. + +maintainers: + - Wei Fang <wei.fang@xxxxxxx> + - Clark Wang <xiaoning.wang@xxxxxxx> + +properties: + compatible: + enum: + - nxp,imx95-netc-blk-ctrl + + reg: + minItems: 2 + maxItems: 3 + + reg-names: + minItems: 2 + items: + - const: ierb + - const: prb + - const: netcmix + + "#address-cells": + const: 2 + + "#size-cells": + const: 2 + + ranges: true + + clocks: + items: + - description: NETC system clock + + clock-names: + items: + - const: ipg_clk + + power-domains: + maxItems: 1 + +patternProperties: + "^pcie@[0-9a-f]+$": + $ref: /schemas/pci/host-generic-pci.yaml# + +required: + - compatible + - "#address-cells" + - "#size-cells" + - reg + - reg-names + - ranges + +unevaluatedProperties: false + +examples: + - | + bus { + #address-cells = <2>; + #size-cells = <2>; + + netc_blk_ctrl: netc-blk-ctrl@4cde0000 { + compatible = "nxp,imx95-netc-blk-ctrl"; + reg = <0x0 0x4cde0000 0x0 0x10000>, + <0x0 0x4cdf0000 0x0 0x10000>, + <0x0 0x4c81000c 0x0 0x18>; + reg-names = "ierb", "prb", "netcmix"; + #address-cells = <2>; + #size-cells = <2>; + ranges; + clocks = <&scmi_clk 98>; + clock-names = "ipg_clk"; + power-domains = <&scmi_devpd 18>; + + pcie_4cb00000: pcie@4cb00000 { + compatible = "pci-host-ecam-generic"; + reg = <0x0 0x4cb00000 0x0 0x100000>; + #address-cells = <3>; + #size-cells = <2>; + device_type = "pci"; + bus-range = <0x1 0x1>; + ranges = <0x82000000 0x0 0x4cce0000 0x0 0x4cce0000 0x0 0x20000 + 0xc2000000 0x0 0x4cd10000 0x0 0x4cd10000 0x0 0x10000>; + + netc_emdio: mdio@0,0 { + compatible = "nxp,netc-emdio", "pci1131,ee00"; + reg = <0x010000 0 0 0 0>; + #address-cells = <1>; + #size-cells = <0>; + }; + }; + }; + }; -- 2.34.1
