Do this and the driver breaks the build so it needs to depend on

 drivers/usb/phy/phy-mv-u3d-usb.c:42:2: error: implicit declaration of 
 function ‘writel_relaxed’ [-Werror=implicit-function-declaration]

This sort of proves that a driver that depends on an unknown Kconfig
symbol gets no build coverage (and will bit rot).

 Sorry, I can't take this as-is.

My mistake, I should have spotted this when looking a Richard's patch.

Some background (which I quickly dug up): config MV_U3D_PHY got added in
v3.7 through commit a67e76ac904c (usb: phy: mv_u3d: Add usb phy driver
for mv_u3d). It then depended on USB_MV_U3D. And that symbol depended
on CPU_MMP3 at that time. Ie, MV_U3D_PHY was unbuildable when it was
added.

In commit 60630c2eabd4 (usb: gadget: mv_u3d: drop ARCH dependency)
MV_U3D_PHY was made depended directly on  CPU_MMP3. That kept it
unbuildable, of course.

Richard, assuming you agree with the above short history of MV_U3D_PHY,
would you mind sending a v2 that removes this unbuildable driver?

This symbol first popped up as a dependency in v3.6, through commit
3d4eb9dfa3e8 (usb: gadget: mv: Add USB 3.0 device driver for Marvell
PXA2128 chip.). The Kconfig symbol itself was never added.

You should remove the reference to MMP3 in the help text (not displayed
here) too, I'd guess. Aside from that:
