musb_in_tusb() is always set to 0, because CONFIG_USB_TUSB6010 is never
set (it should have been CONFIG_USB_MUSB_TUSB6010). But musb_in_tusb()
is unused anyway, so remove a few lines of dead code.

net: get rid of SET_ETHTOOL_OPS
Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.
Mostly done via coccinelle script:
@@
struct ethtool_ops *ops;
struct net_device *dev;
@@
- SET_ETHTOOL_OPS(dev, ops);
+ dev->ethtool_ops = ops;
Compile tested only, but I'd seriously wonder if this broke anything.

By adding COMPILE_TEST to the list of dependencies
we can build test this driver on all other architectures
which is very valuable for maintainers applying patches

Since we are about to introduce new methods (read_iter/write_iter), the
tests in a bunch of places would have to grow inconveniently. Check
once (at open() time) and store results in ->f_mode as FMODE_CAN_READ
and FMODE_CAN_WRITE resp. It might end up being a temporary measure -
once everything switches from ->aio_{read,write} to ->{read,write}_iter
it might make sense to return to open-coded checks. We'll see...

Per reference manuals of Freescale P1020 and P2020 SoCs, USB controller
present in these SoCs has bit 17 of USBx_CONTROL register marked as
Reserved - there is no PHY_CLK_VALID bit there.
Testing for this bit in ehci_fsl_setup_phy() behaves differently on two
P1020RDB boards available here - on one board test passes and fsl-usb
init succeeds, but on other board test fails, causing fsl-usb init to
fail.
This patch changes ehci_fsl_setup_phy() not to test PHY_CLK_VALID on
controller version 1.6 that (per manual) does not have this bit.

Some OHCI controllers from ATI/AMD seem to have difficulty with
"global" USB suspend, that is, suspending an entire USB bus without
setting the suspend feature for each port connected to a device. When
we try to resume the child devices, the controller gives timeout
errors on the unsuspended ports, requiring resets, and can even cause
ohci-hcd to hang; see
http://marc.info/?l=linux-usb&m=139514332820398&w=2
and the following messages.
This patch fixes the problem by adding a new quirk flag to ohci-hcd.
The flag causes the ohci_rh_suspend() routine to suspend each
unsuspended, enabled port before suspending the root hub. This
effectively converts the "global" suspend to an ordinary root-hub
suspend. There is no need to unsuspend these ports when the root hub
is resumed, because the child devices will be resumed anyway in the
course of a normal system resume ("global" suspend is never used for
runtime PM).
This patch should be applied to all stable kernels which include
commit 0aa2832dd0d9 (USB: use "global suspend" for system sleep on
USB-2 buses) or a backported version thereof.

Select the secondary PHY using the TCSR register, if phy-num=1
in the DTS (or phy_number is set in the platform data). The
SOC has 2 PHYs which can be used with the OTG port, and this
code allows configuring the correct one.
Note: This resolves the problem I was seeing where I couldn't
get the USB driver working at all on a dragonboard, from cold
boot. This patch depends on patch 5/14 from Ivan's msm USB
patch set. It does not use DT for the register address, as
there's no evidence that this address changes between SoC
versions.

On few legacy platforms, USB PHY is having dedicated reset clk.
It is used to reset USB PHY after putting USB PHY into low power
mode and for calibration of USB PHY. Putting USB PHY into low
power mode is causing ulpi read/write timeout as expected. USB PHY
reset clk is not available on newer platform.
For 28nm PHY, reset USB PHY after resetting USB LINK.
Also reset USB PHY using USB_PHY_PON bit with USB_OTG_HS_PHY_CTRL
register after programming USB PHY Override registers as suggested
with hardware programming guidelines.
