usb: musb: patches for v3.9 merge window
Mostly fixes all over which weren't urgent enough for
the late -rc cycle.
There is a Double Buffering fix for Host Mode TX,
a dependency fix for the transceiver driver, some
fixes to the error path and a fix for the use of
omap_musb_maibox.
Other than these fixes, there a removal duplicate
headers from the dsps glue layer and removal of
redundant assignments in omap2430_probe().

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.
devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

"54db6ee ARM: OMAP2+: Introduce local usb.h" moved control module bit
definitions from plat/usb.h (which dsps glue was using) to a local
header in mach-omap2. And in parallel,
"c68bb4c usb: musb: dsps: control module handling (quirk)" added
control module handling capability to dsps glue driver that used
those control module bit definitions.
Integration of above two changes would cause build error in musb dsps
glue driver (they go through different trees upstream) as is seen now
in linux-next. Fix it by adding necessary definitions in dsps glue
driver.

USB gadget patches from Felipe:
"usb: gadget: patches for v3.8
renesas_usbhs implements ->pullup() method, switches over
to devm_request_irq(), adds support for DMA Engine and
got a few miscelaneous cleanups.
The NCM gadget got an endianness fix and the Ethernet
gadget a frame size fix.
We're finally removing the g_file_storage gadget and
sticking to g_mass_storage and the new tcm_usb_gadget
gadgets since that was a huge duplicaton of effort anyway.
While removing g_file_storage, we also had to fix a bunch
of defconfigs which were still pointing to the old gadget.
There's a big series getting us closer to being able to
introduce our configfs interface. The series converts
functions into loadable modules which will, eventually,
be registered to the configfs interface.
Other than that there's the usual typo fixes and miscelaneous
cleanups all over the place."

USB musb merge from Felipe:
"usb: musb: patches for v3.8 merge window
We have here the usual set of cleanups for the MUSB driver; a
big set of patches converting platform_device_del() and
platform_device_put() into platform_device_unregister().
Another big set was applied converting to module_platform_driver()
macro in order to reduce some boilerplate code from all glue
layers.
Other than that, we had a series fixing one known silicon errata
where we couldn't read a few registers. In order to fix that
we're now using shadow variables for reads and only writing
to the registers which are known to break functionality when
read."

This reverts commit d8c3ef256f88b7c6ecd673d03073b5645be9c5e4.
Above mentioned change was made along with multi usb phy change and
adding DT support for nop transceiver. But other two changes did not
make it to mainline. This in effect makes dsps musb wrapper unusable
even for single instance.
Hence revert it so that at least single instance can be supported.

am335x uses nop transceiver driver and need to enable builtin phy
by writing into usb_ctrl register available in system control
module register space. This is being added at musb glue driver
layer until a separate system control module driver is available.
Proper solution is to make use of control module driver, but it is
not expected to be ready soon.
Other options available are providing control module register space
as memory resource via DT or using omap hwmod.
DT approach has been rejected by Rob Herring, while resources are
being moved from hwmod to DT. And both of the above approaches
require that control module registers be configured in wrapper
itself requring a quirk in driver as well as DT or hwmod.
Here another option is used, providing driver with control module
register physical address. Even though this a hack, there is no other
option left till control module driver is ready. As of now only
am335x is using dsps wrapper, and so driver is made aware of am335x
control module physical address.
Please note that this is a temporary arrangment till omap control
module driver is available.

Currently multiple phy's of the same type are not supported, hence
reduce musb instances to one. This helps in supporting at least one
instance of musb, rather than having none. Even without this, it was
observed that both instances were working (by luck), but this holds
good iff wrapper is part of Image. And it is not correct for both
controller's to be associated with same phy, here it was working
because phy is a nop one. And having wrapper as a module and
rmmod'ing would crash.
This can be reverted once multi phy support for same type is available
and driver is enhanced to make use of it.

This replaced the handcrafted id handling by the PLATFORM_DEVID_AUTO
value which should do the same thing.
This patch probably also fixes ux500 because I did not find the "musbid"
variable to remove. And we close a tiny-unlikely race window becuase the
old code gave the id back before device was destroyed in the remove
case.

platform_device_unregister() only calls platform_device_del() and
platform_device_put(), thus use platform_device_unregister() to
simplify the code.
Also the documents in platform.c shows that platform_device_del
and platform_device_put must _only_ be externally called in error
cases. All other usage is a bug.

follows:
sprintf(res_name, "port%d-mode", id);
Hence, res_name must be at least 11 characters long in order to store

While at it, use to snprintf() rather than sprintf() when accessing this

usb: musb: patches for v3.7 merge window
Here we have a bunch of miscellaneous cleanups and fixes
to the musb driver. It fixes a bunch of mistakes errors
which nobody has triggered before, so I'm not Ccing stable
tree.
We are finally improving OMAP's VBUS/ID Mailbox usage so
that we can introduce our PHY drivers properly. Also, we're
adding support for multiple instances of the MUSB IP in
the same SoC, as seen on some platforms from TI which
have 2 MUSB instances.
Other than that, we have some small fixes like not kicking
DMA for a zero byte transfer, or properly handling NAK timeout
on MUSB's host side, and the enabling of DMA Mode1 for any
transfers which are aligned to wMaxPacketSize.
All patches have been pending on mailing list for a long time
and I don't expect any big surprises with this pull request.

usb: xceiv: patches for v3.7 merge window
nop xceiv got its own header to avoid polluting otg.h. It has also
learned to work as USB2 and USB3 phys so we can use it on USB3
controllers.
Together with those two changes to nop xceiv, we're adding basic
PHY support to dwc3 driver, this is to allow platforms which actually
have a SW-controllable PHY talk to them through dwc3 driver.
We're adding a new phy driver for the OMAP architecture. This driver
is for the PHY found in OMAP4 SoCs, and a new phy driver for the
marvell architecture. An extra phy driver - for Tegra SoCs - is now
moving from arch/arm/mach-tegra* to drivers/usb/phy.
Also here, there's the creation of <linux/usb/phy.h> which should be
used from now on for PHY drivers, even those which don't support
OTG.
