The Odroid U3 (Exynos 4412 based) for instance needs this driver,
otherwise its USB hub will not come up.
exynos_defconfig already has this enabled as built-in, too. So
just doing the same here in multi_v7_defconfig.

Thanks to Tobias Jakobi, who indirectly made me aware of why USB
did not work for me.

Partially this was part of my patchset fixing powersequence for
usb3503 and lan9730:
https://patchwork.kernel.org/patch/9502939/
but that patch waits still for power sequence.
Anyway please define this as a module (unless it can't... but it
worked in my case).
Best regards,
Krzysztof

Hi Krzysztof,
Thanks for your quick reply!

In that case you used an initrd, right? I see various cases of USB
built-ins, like CONFIG_USB_STORAGE=y, CONFIG_USB_DWC2=y and so on in
multi_v7_defconfig. So my impression was that multi_v7_defconfig was
supposed to allow booting a rootfs from a USB storage device even
without an initrd.
Let me know if that impression is wrong though, I'll happily resend
(and test) the patch with CONFIG_USB_HSIC_USB3503=m then :-).
Regards, Linus

We use modules for multi_v7 as much as possible with that exception as
fair as I remember - no need of initramfs/initrd for boots. If this is
your intention, please mention this in commit message ("using usb3503
as builtin to provide boot from USB without initrd/initramfs").
Best regards,
Krzysztof
