[PATCH v9 0/4] Enable IPQ5332 USB2

[PATCH v9 0/4] Enable IPQ5332 USB2

[Varadarajan Narayanan]

This patch series adds the relevant phy and controller
DT configurations for enabling USB2 on IPQ5332

v9:
	Driver: Since the driver code has been picked up for merge,
		(https://lore.kernel.org/linux-arm-msm/169226613917.81413.1200008047604336868.b4-ty@kernel.org/)
		adding the coding style fixes alone in this patch.

		Fix line break alignment
		Remove register success print
	DTS:	usb2@8a00000 -> usb@8a00000
		regulator_fixed_5p0: s0500 -> regulator_fixed_5p0: regulator
v8:
	Driver:-
		Change commit subject and message per review comments
		Don't include of_platform.h
		Change struct initialization coding style
		GENMASK -> BIT for one of the defines
v7:
	Binding:-
		Move 'compatible' to be the first entry
		In the example have 'usb-phy' instead of 'usb2-phy'
		Add 'Reviewed-by: Krzysztof Kozlowski'
v6:
	Binding and dts:-
		Dropped the qcom,dwc3.yaml patch as it has been picked up for linux-next
		Add const to compatible, vdd-supply
		Move nodes per register address
	Driver:-
		Add vdd-supply
		Cleanup error paths in probe with dev_err_probe
v5:
	Binding and dts:-
		Fix email id
		Removed 'Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>'
		as had to change bindings file to be able to use generic phy instead of
		usb-phy

	Driver:-
		Remove unused definition
		Use generic phy instead of usb-phy
v4:
	Binding and dts:-
		Change node name (bindings & dts)
	Driver:-
		Remove unused enum
		static const for '.data'
		Error handling for devm_clk_get
v3:
	Fix bindings file based on review comments

v1:
	Cleanup DTS
	Combine driver, kconfig and makefile patches
	Remove unused functions from M31 driver
	Drop the clock driver changes

But why are you trying to fix this? aligning next line to the opening
bracket is perfectly fine (and is one of the endorsed styles).

This is irrelevant to the indentation.

Ugh, excuse me. My mailer displayed alignment in a wrong way.

This LGTM except the last chunk (removal of the info message).
