In case of error, the function usb_get_phy() returns ERR_PTR() and never
returns NULL. The NULL test in the return value check should be replaced
with IS_ERR().

This patch set is based on the latest Felipe's usb.git / testing/next branch.
(commit id = fcb8eae8d83c12770f8de915df01f7191dc697a3)
I submitted this patch set as RFC in last month and nobody said anything.
So, I submitted this without RFC :)
Changes from RFC version:
- rebase on the latest test
This patch adds to support no_skb_reserve function to improve
performance for some platforms. About the detail, please refer to
the commit log of "quirk_avoids_skb_reserve" in
include/linux/usb/gadget.h.

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.

Some platforms (e.g. USB-DMAC on R-Car SoCs) has memory alignment
restriction. If memory alignment is not match, the usb peripheral
driver decides not to use the DMA controller. Then, the performance
is not good.
In the case of u_ether.c, since it calls skb_reserve() in rx_submit(),
it is possible
This patch sets the quirk_avoids_skb_reserve flag to improve performance
of a network gadget driver (e.g. f_ncm.c) if USB-DMAC is used.
For example (on r8a7795 board + f_ncm.c + iperf udp mode / receiving):
- without this patch: 90.3 Mbits/sec
- withthis patch: 273 Mbits/sec

The USB Type-C class is meant to provide unified interface to the
userspace to present the USB Type-C ports in a system.
Changes since v5:
- Only updating the roles based on driver notifications
- Added MODULE_ALIAS for the WhiskeyCove module
- Including the patch that creates the actual platform
The purpose of USB Type-C connector class is to provide
unified interface for the user space to get the status and
basic information about USB Type-C connectors on a system,
control over data role swapping, and when the port supports
USB Power Delivery, also control over power role swapping
and Alt
Intel WhiskeyCove PMIC has also a USB Type-C PHY, so let's
create a device for it.

the CMDACT bit in the DEPCMD register after issuing an ENDXFER command.
This feature is enabled by writing GUCTL2[14].

I have a few questions for one or both of you. I'm not really an expert
