This patch removes a fixme message in this file:wq for setting the usb 2
speed on the board to the correct level. We need to depend on the

things on the board with the usb chipset.

The R-Car H2 and M2 SoCs come with an xHCI controller that requires

This patch adds the USB xHCI support for the R-Car H2 and M2 SoCs.
These SoCs use an xHCI but still need specific initialization, mainly
to setup the firmware downloading and the specific registers.
This patch set is based on the usb-next branch of Greg usb.git tree.

Hello Himangi Saraogi,
The patch 9f7b23ce88e9: "usb: phy: phy-gpio-vbus-usb: use devm_
functions" from Jun 4, 2014, leads to the following static checker
warning:
drivers/usb/phy/phy-gpio-vbus-usb.c:264 gpio_vbus_probe()
warn: passing devm_ allocated variable to kfree. 'gpio_vbus'
-ENODEV is interpreted by the generic driver probing function as a
non-matching driver. This leads to a missing probe failure message.
Also a missing USB PHY is more of an invalid configuration of the usb
driver because it is necessary.
This patch returns -EINVAL if devm_usb_get_phy_by_phandle()
fsl,usbphy is no optional property. This patch moves it to the list of
required properties.

Dear Matt,
This is a small series which fix usbg_set_function_attrs()
which previously tried to set attributes which are read only
on configfs.
I have also went through code and marked attributes which should not
change during function calls with const qualifiers.
Third patch is a small enhancem
Some of function attributes are read only on configfs, so library
should not try to set them and accept only empty values in functions
which set multiple attributes at single call.
