To resolve this, usb3_phy should be moved to a child -node of the internal MDIO bus. The result is heavily based upon Vivek's -patch. This has also been cross-referenced with Yendapally Reddy's -earlier work which utilised the subsequently dropped brcm,nsp-usb3-phy -driver: "[PATCH v2 4/4] arm: dts: nsp: Add USB nodes to device tree" -[2]. Finally, this change provides conformance to the bcm-ns-usb3-phy -documentation, utilising the required usb3-dmp-syscon property. Note -that support for the deprecated ccb-mii bindings has been dropped as of -"phy: phy-bcm-ns-usb3: drop support for deprecated DT binding"[3]. - -[1] https://lore.kernel.org/patchwork/patch/933971/ -[2] https://www.spinics.net/lists/arm-kernel/msg555132.html -[3] https://lore.kernel.org/linux-devicetree/20201113113423.9466-1-zajec5@gmail.com/ - -Signed-off-by: Matthew Hagan <mnhagan88@gmail.com> -Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> ---- - arch/arm/boot/dts/bcm-nsp.dtsi | 38 +++++++++++++++++++++++++++------- - 1 file changed, 31 insertions(+), 7 deletions(-) - ---- a/arch/arm/boot/dts/bcm-nsp.dtsi -+++ b/arch/arm/boot/dts/bcm-nsp.dtsi -@@ -370,6 +370,35 @@ - #address-cells = <1>; - }; - -+ mdio-mux@32000 { -+ compatible = "mdio-mux-mmioreg"; -+ reg = <0x32000 0x4>; -+ mux-mask = <0x200>; -+ #address-cells = <1>; -+ #size-cells = <0>; -+ mdio-parent-bus = <&mdio>; -+ -+ mdio_int: mdio@0 { -+ reg = <0x0>; -+ #address-cells = <1>; -+ #size-cells = <0>; -+ -+ usb3_phy: usb3-phy@10 { -+ compatible = "brcm,ns-bx-usb3-phy"; -+ reg = <0x10>; -+ usb3-dmp-syscon = <&usb3_dmp>; -+ #phy-cells = <0>; -+ status = "disabled"; -+ }; -+ }; -+ -+ mdio_ext: mdio@200 { -+ reg = <0x200>; -+ #address-cells = <1>; -+ #size-cells = <0>; -+ }; -+ }; -+ - rng: rng@33000 { - compatible = "brcm,bcm-nsp-rng"; - reg = <0x33000 0x14>; -@@ -528,13 +557,8 @@ - }; - }; - -- usb3_phy: usb3-phy@104000 { -- compatible = "brcm,ns-bx-usb3-phy"; -- reg = <0x104000 0x1000>, -- <0x032000 0x1000>; -- reg-names = "dmp", "ccb-mii"; -- #phy-cells = <0>; -- status = "disabled"; -+ usb3_dmp: syscon@104000 { -+ reg = <0x104000 0x1000>; - }; - }; - |
