This patchset consists of some bug fixes and feature enhancements for

basic testing without dma was also done.

This is based on initial code to get the Allwinner sunxi musb controller
supported by Chen-Yu Tsai and Roman Byshko.
This adds support for the Allwinner sunxi musb controller in both host only
and otg mode. Peripheral only mode is not supported, as no boards use that.
This has been tested on a cu

This patch set adds a new API to get phy by index when multiple
phys are present. This patch is based on discussion with Arnd Bergmann
about dt bindings for multiple phys.
Arun Ramamurthy (3):
phy: core: Add devm_of_phy_get_by_index to phy-core
usb: ehci-platform: Use devm_of_phy_get_by_inde
Getting phys by index instead of phy names so that the dt

The MUSB test mode register can only be set once, otherwise the result
is undefined.
This prevents the debugfs testmode entry to set the register more than
once which causes test failure.
