[PATCH 01/29] usb: gadget: mv_udc: use udc_start and udc_stop functions

[PATCH 01/29] usb: gadget: mv_udc: use udc_start and udc_stop functions

[Chao Xie]

From: Chao Xie <chao.xie@marvell.com>

udc_start and udc_stop reduce code duplication in comparison to
start and stop generalising calls done by all drivers
(i.e. bind and unbind) and moving these calls to common code.

[PATCH 19/29] usb: phy: mv_usb2_phy: add externel chip support

[Chao Xie]

From: Chao Xie <chao.xie@marvell.com>

For the vbus and idpin detection. It may be completed by some
external chip.
The controller need clock on and PHY enabled to detect the
vbus/idpin. It will increase the power. So using the external
chip to detect the vbus and idpin can save the power.

[PATCH 06/29] usb: host: ehci-mv: fix clk APIs

I don't like patches with no patch description.  You should write 
something here, explaining why the change is needed.  What's wrong with 
the clk APIs?

The same hold for your other patches, except perhaps the trivial one 
that removes an unused local variable definition.
