Subject: [PATCH v2 0/7] musb: Update to use generic PHY

Hi,

This patchset updates the musb core to add support for the generic PHY
framework.

It also updates the jz4740 driver to use the generic PHY driver
(drivers/phy/ingenic/phy-ingenic-usb.c) instead of the USB PHY one
(drivers/usb/phy/phy-jz4770.c) which is then removed.

If you are looking for the V1, it was sent two years ago [1] and
received zero feedback.

Anyway, V1 had only patches 1-4 and if I'm not mistaken the V2 patches
are exactly the same.

Patches 5-7 are new, and update the jz4740 driver to support generic
PHYs, and ultimately remove the old phy-jz4770 USB PHY driver which has
been replaced.

Cheers,
-Paul
