Also, there are a lot more operating points for the A33, see:
https://github.com/QSchulz/linux/blob/v4.9-rc4_adc_a31_v7/cpufreq_a33/arch/arm/boot/dts/sun8i-a33.dtsi#L323-L340
They are present in the Allwinner Linux source code and in the fex of
all A33-based boards.
Is there a reason for not adding all opp?

When phy-sun4i-usb's probing fails, it does not print the reason in
kernel log, forcing the developer to edit this driver to add info logs.
This commit makes the kernel print the reason of phy-sun4i-usb's probing
failure or a success message.

MFD_SUN4I_GPADC and TOUCHSCREEN_SUN4I are incompatible (both are drivers
for Allwinner SoCs' ADC). This makes sure TOUCHSCREEN_SUN4I isn't
enabled while MFD_SUN4I_GPADC is enabled.

le of not registering the thermal

most use cases, the SoC temperature is more critical (for cpu throttling
for example or activating cooling devices) than ADC readings, thus it is
now enabled by default.

This driver probes on three different platform_device_id to take into
