05f6b0ff68 usb: gadget: u_ether: add a flag to avoid skb_reserve() calling 
This patch adds a flag "no_skb_reserve" in struct eth_dev.
So, if a peripheral driver sets the quirk_avoids_skb_reserve flag,
upper network gadget drivers (e.g. f_ncm.c) can avoid skb_reserve()
calling using the flag as well.

238b7bd91b usb: usbip: vudc: fix left shift overflow 
In v_recv_cmd_submit(), urb_p->urb->pipe has the type unsigned int
(which is 32-bit long on x86_64) but 11<<30 results in a 34-bit integer.
Therefore the 2 leading bits are truncated and

    urb_p->urb->pipe &= ~(11 << 30);

has the same meaning as

    urb_p->urb->pipe &= ~(3 << 30);

This second statement seems to be how the code was intended to be
written, as PIPE_ constants have values between 0 and 3.

The overflow has been detected with a clang warning:

    drivers/usb/usbip/vudc_rx.c:145:27: warning: signed shift result
    (0x2C0000000) requires 35 bits to represent, but 'int' only has 32
    bits [-Wshift-overflow]
            urb_p->urb->pipe &= ~(11 << 30);
                                  ~~ ^  ~~

6ebb8f0f83 usb: ohci-sa1111: remove machine_has_neponset() 
The neponset is a daughter board for the Assabet platform, which has a
SA1111 chip on it.  If we're initialising the SA1111 OHCI, and we're
part of a neponset, the host platform must be an Assabet.

This allows us to eliminate machine_has_neponset() from this driver,
replacing it instead with machine_is_assabet(), and killing the
mach/assabet.h include.

2e2aa1bc7e usb: ohci-at91: Forcibly suspend ports while USB suspend 
The usb controller does not manage correctly the suspend mode for
the ehci. In echi mode, there is no way to suspend without any
device connected to it. This is why this specific control is added
to fix this issue. Since the suspend mode works in ohci mode, this
specific control works by suspend the usb controller in ohci mode.

This specific control is by setting the SUSPEND_A/B/C fields of
SFR_OHCIICR(OHCI Interrupt Configuration Register) in the SFR
while the OHCI USB suspend.

This set operation must be done before the USB clock disabled,
clear operation after the USB clock enabled.
