Please also use a Fixes: for this, so it can be applied onto stable kernels as well. > > Signed-off-by: Gowtham Tammana <g-tammana@ti.com> > --- > arch/arm/boot/dts/dra74x.dtsi | 69 +++++++++++++---------------------- > 1 file changed, 25 insertions(+), 44 deletions(-) > > diff --git a/arch/arm/boot/dts/dra74x.dtsi b/arch/arm/boot/dts/dra74x.dtsi > index e1850d6c841a..6410ddbf0fca 100644 > --- a/arch/arm/boot/dts/dra74x.dtsi > +++ b/arch/arm/boot/dts/dra74x.dtsi > @@ -49,50 +49,6 @@ dsp2_system: dsp_system@41500000 { > reg = <0x41500000 0x100>; > }; > > - target-module@48940000 { > - compatible = "ti,sysc-omap4", "ti,sysc"; > - reg = <0x48940000 0x4>, > - <0x48940010 0x4>; > - reg-names = "rev", "sysc"; > - ti,sysc-mask = <SYSC_OMAP4_DMADISABLE>; > - ti,sysc-midle = <SYSC_IDLE_FORCE>, > - <SYSC_IDLE_NO>, > - <SYSC_IDLE_SMART>, > - <SYSC_IDLE_SMART_WKUP>; > - ti,sysc-sidle = <SYSC_IDLE_FORCE>, > - <SYSC_IDLE_NO>, > - <SYSC_IDLE_SMART>, > - <SYSC_IDLE_SMART_WKUP>; > - clocks = <&l3init_clkctrl DRA7_L3INIT_USB_OTG_SS4_CLKCTRL 0>; > - clock-names = "fck"; > - #address-cells = <1>; > - #size-cells = <1>; > - ranges = <0x0 0x48940000 0x20000>; > - > - omap_dwc3_4: omap_dwc3_4@0 { > - compatible = "ti,dwc3"; > - reg = <0 0x10000>; > - interrupts = <GIC_SPI 346 IRQ_TYPE_LEVEL_HIGH>; > - #address-cells = <1>; > - #size-cells = <1>; > - utmi-mode = <2>; > - ranges; > - status = "disabled"; > - usb4: usb@10000 { > - compatible = "snps,dwc3"; > - reg = <0x10000 0x17000>; > - interrupts = <GIC_SPI 345 IRQ_TYPE_LEVEL_HIGH>, > - <GIC_SPI 345 IRQ_TYPE_LEVEL_HIGH>, > - <GIC_SPI 346 IRQ_TYPE_LEVEL_HIGH>; > - interrupt-names = "peripheral", > - "host", > - "otg"; > - maximum-speed = "high-speed"; > - dr_mode = "otg"; > - }; > - }; > - }; > - > target-module@41501000 { > compatible = "ti,sysc-omap2", "ti,sysc"; > reg = <0x41501000 0x4>, > @@ -224,3 +180,28 @@ &pcie1_ep { > &pcie2_rc { > compatible = "ti,dra746-pcie-rc", "ti,dra7-pcie"; > }; > + > +&usb4_tm { > + omap_dwc3_4: omap_dwc3_4@0 { > + compatible = "ti,dwc3"; > + reg = <0 0x10000>; > + interrupts = <GIC_SPI 346 IRQ_TYPE_LEVEL_HIGH>; > + #address-cells = <1>; > + #size-cells = <1>; > + utmi-mode = <2>; > + ranges; > + status = "disabled"; > + usb4: usb@10000 { > + compatible = "snps,dwc3"; > + reg = <0x10000 0x17000>; > + interrupts = <GIC_SPI 345 IRQ_TYPE_LEVEL_HIGH>, > + <GIC_SPI 345 IRQ_TYPE_LEVEL_HIGH>, > + <GIC_SPI 346 IRQ_TYPE_LEVEL_HIGH>; > + interrupt-names = "peripheral", > + "host", > + "otg"; > + maximum-speed = "high-speed"; > + dr_mode = "otg"; > + }; > + }; > +}; Tony, This can be fixed in couple of different ways, and I see there have been different commits that have ultimately caused this. 6b14eb4705d6 ("ARM: dts: DRA7: Move USB_OTG 4 to dra74x.dtsi") 549fce068a31 ("ARM: dts: dra7: Add l4 interconnect hierarchy and ti-sysc data" bcbb63b80284 (ARM: dts: dra7: Separate AM57 dtsi files") c7b72abca61e ("ARM: OMAP2+: Drop legacy platform data for dra7 dwc3") Would you prefer that we just drop the USB4 target-module reference in dra7-l4.dtsi following the first commit? regards Suman

USB4 device node which is defined in [1] is redefined in here causing boot failures. Remove the duplicated entry and instead extend it with child node info through corresponding label reference.
