This range +overlaps with MDIO cmd and param registers (<0x18003000 0x8>). +Essentially, the platform driver partly acts like a MDIO bus driver, +hence to use of this register range. + +In some Northstar devices like Linksys EA9500, secondary switch is +connected via external MDIO. The only way to access and configure the +external switch is via MDIO bus. When we enable the MDIO bus in it's +current state, the MDIO bus and any child buses fail to register because +of the register range overlap. + +On Northstar, the USB 3.0 PHY is connected at address 0x10 on the +internal MDIO bus. This change moves the usb3_phy node and makes it a +child node of internal MDIO bus. + +Thanks to Rafał Miłecki's commit af850e14a7ae ("phy: bcm-ns-usb3: add +MDIO driver using proper bus layer") the same USB 3.0 platform driver +can now act as USB 3.0 PHY MDIO driver. + +Tested on Linksys Panamera (EA9500) + +Signed-off-by: Vivek Unune <npcomplete13@gmail.com> +Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> +--- + arch/arm/boot/dts/bcm4708-asus-rt-ac56u.dts | 4 +++ + arch/arm/boot/dts/bcm4708-asus-rt-ac68u.dts | 4 +++ + arch/arm/boot/dts/bcm4708-buffalo-wzr-1750dhp.dts | 4 +++ + arch/arm/boot/dts/bcm4708-linksys-ea6300-v1.dts | 4 +++ + arch/arm/boot/dts/bcm4708-luxul-xap-1510.dts | 4 +++ + arch/arm/boot/dts/bcm4708-luxul-xwc-1000.dts | 4 +++ + arch/arm/boot/dts/bcm4708-netgear-r6250.dts | 4 +++ + arch/arm/boot/dts/bcm4708-netgear-r6300-v2.dts | 4 +++ + arch/arm/boot/dts/bcm4708-smartrg-sr400ac.dts | 4 +++ + arch/arm/boot/dts/bcm47081-asus-rt-n18u.dts | 4 +++ + arch/arm/boot/dts/bcm47081-buffalo-wzr-600dhp2.dts | 4 +++ + arch/arm/boot/dts/bcm47081-buffalo-wzr-900dhp.dts | 4 +++ + arch/arm/boot/dts/bcm47081-luxul-xap-1410.dts | 4 +++ + arch/arm/boot/dts/bcm47081-luxul-xwr-1200.dts | 4 +++ + arch/arm/boot/dts/bcm47081-tplink-archer-c5-v2.dts | 4 +++ + arch/arm/boot/dts/bcm4709-asus-rt-ac87u.dts | 4 +++ + arch/arm/boot/dts/bcm4709-buffalo-wxr-1900dhp.dts | 4 +++ + arch/arm/boot/dts/bcm4709-linksys-ea9200.dts | 4 +++ + arch/arm/boot/dts/bcm4709-netgear-r7000.dts | 4 +++ + arch/arm/boot/dts/bcm4709-netgear-r8000.dts | 4 +++ + arch/arm/boot/dts/bcm4709-tplink-archer-c9-v1.dts | 4 +++ + arch/arm/boot/dts/bcm47094-dlink-dir-885l.dts | 4 +++ + arch/arm/boot/dts/bcm47094-linksys-panamera.dts | 4 +++ + arch/arm/boot/dts/bcm47094-luxul-abr-4500.dts | 4 +++ + arch/arm/boot/dts/bcm47094-luxul-xbr-4500.dts | 4 +++ + arch/arm/boot/dts/bcm47094-luxul-xwr-3100.dts | 4 +++ + arch/arm/boot/dts/bcm47094-netgear-r8500.dts | 4 +++ + arch/arm/boot/dts/bcm47094.dtsi | 7 +++-- + arch/arm/boot/dts/bcm5301x.dtsi | 35 +++++++++++++++++----- + arch/arm/boot/dts/bcm94708.dts | 4 +++ + arch/arm/boot/dts/bcm94709.dts | 4 +++ + arch/arm/boot/dts/bcm953012er.dts | 4 +++ + arch/arm/boot/dts/bcm953012hr.dts | 4 +++ + arch/arm/boot/dts/bcm953012k.dts | 4 +++ + 34 files changed, 159 insertions(+), 11 deletions(-) + +--- a/arch/arm/boot/dts/bcm4708-asus-rt-ac56u.dts ++++ b/arch/arm/boot/dts/bcm4708-asus-rt-ac56u.dts +@@ -90,3 +90,7 @@ + };
