Stream mode enable is known for better performance, this stream mode
enable patch has been passed with stress tests at device mode for
imx6sl and imx6sx, and no issue is found.

If usbmisc hasn't probed yet, defer the probe.
It's not enough to check if the platform device for the OF node of the
usbmisc has been registered, but it also needs to have been probed
already before we can call imx_usbmisc_init().
This can happen if the order in which devices are probed change due to
async probing or on-demand probing of dependencies.

Some usb PHYs need power supply from vbus to make it work, eg mxs-phy, if
there is no vbus, USB PHY will not in correct state when the controller starts
to work, for host, this requires vbus should be turned on before setting port
power(PP) of ehci, to work with this kind of USB PHY design, this patch adds
a flag CI_HDRC_TURN_VBUS_EARLY_ON, can be checked by host driver to turn on
vbus while start host.

Pull driver core update from Greg KH:
"Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes,
just removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There
are some ath9k patches coming in through this tree that have been
acked by the wireless maintainers as they relied on the debugfs
changes.
Everything has been in linux-next for a while"

This patch modify the generic code handling PHYs to allow them to be
supplied from the drivers. This adds checks to ensure no PHY was already
there when looking for one in the generic code. This also makes sure we
do not modify its state in the generic HCD functions, it was provided by
the driver.

This adds Vybrid VF610 SoC support. The IP is very similar to i.MX6,
however, the non-core registers are spread in two different register
areas. Hence we support multiple instances of the USB misc driver
and add the driver instance to the imx_usbmisc_data structure.

-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() returned -ENODEV.

Pull DMA mask updates from Russell King:
"This series cleans up the handling of DMA masks in a lot of drivers,
fixing some bugs as we go.
Some of the more serious errors include:
- drivers which only set their coherent DMA mask if the attempt to
set the streaming mask fails.
- drivers which test for a NULL dma mask pointer, and then set the
dma mask pointer to a location in their module .data section -
which will cause problems if the module is reloaded.
To counter these, I have introduced two helper functions:
- dma_set_mask_and_coherent() takes care of setting both the
streaming and coherent masks at the same time, with the correct
error handling as specified by the API.
- dma_coerce_mask_and_coherent() which resolves the problem of
drivers forcefully setting DMA masks. This is more a marker for
future work to further clean these locations up - the code which
creates the devices really should be initialising these, but to fix
that in one go along with this change could potentially be very
disruptive.
The last thing this series does is prise away some of Linux's addition
to "DMA addresses are physical addresses and RAM always starts at
zero". We have ARM LPAE systems where all system memory is above 4GB
physical, hence having DMA masks interpreted by (eg) the block layers
as describing physical addresses in the range 0..DMAMASK fails on
these platforms. Santosh Shilimkar addresses this in this series; the
patches were copied to the appropriate people multiple times but were
ignored.
Fixing this also gets rid of some ARM weirdness in the setup of the
max*pfn variables, and brings ARM into line with every other Linux
architecture as far as those go"
