v12:
	usb2_0_dwc -> usb_dwc
	"make W=1 ARCH=arm64 -j16 CHECK_DTBS=y DT_SCHEMA_FILES=qcom,ipq5332-usb-hsphy.yaml dtbs_check" passed
	"make W=1 ARCH=arm64 -j16 DT_CHECKER_FLAGS='-v -m' dt_binding_check DT_SCHEMA_FILES=qcom,ipq5332-usb-hsphy.yaml" passed

v10:
	usb@8a00000 -> usb@8af8800
	"make W=1 ARCH=arm64 -j 16 CHECK_DTBS=y DT_SCHEMA_FILES=qcom,ipq5332-usb-hsphy.yaml dtbs_check" passed
v9:
	usb2@8a00000 -> usb@8a00000
	"make ARCH=arm64 -j 16 CHECK_DTBS=y DT_SCHEMA_FILES=qcom,ipq5332-usb-hsphy.yaml dtbs_check" passed
v6:
	Remove clock names
	Move the nodes to address sorted location
v5:
	Use generic phy instead of usb-phy
	'make CHECK_DTBS=y DT_SCHEMA_FILES=qcom dtbs_check' passed
	'DT_CHECKER_FLAGS='-v -m' DT_SCHEMA_FILES=qcom dt_binding_check' passed
v4:
	Change node name
	Remove blank line
	'make CHECK_DTBS=y DT_SCHEMA_FILES=qcom qcom/ipq5332-rdp441.dtb' passed
v1:
	Rename phy node
	Change compatible from m31,ipq5332-usb-hsphy -> qcom,ipq5332-usb-hsphy
	Remove 'qscratch' from phy node
	Fix alignment and upper-case hex no.s
	Add clock definition for the phy
	Remove snps,ref-clock-period-ns as it is not used. dwc3_ref_clk_period()
	in dwc3/core.c takes the frequency from ref clock and calculates fladj
	as appropriate.
