Greg Kroah-Hartman 73ad0adcb6 usb: changes for v3.14 merge window
This pull request is quite extensive, containing
 105 non-merge commits. Because of that, we describe
 the changes in sections below:
 
 New drivers:

 	- Aeroflex Gaisler GRUSBDC
 	- Tahvo PHY driver for N770
 	- JZ4740 MUSB gluer Layer
 	- Broadcom PHY Driver
 
 Important new features:
 	- MUSB DSPS learned about suspend/resume
 	- New quirk_ep_out_aligned_size flag added to struct usb_gadget
 	- DWC3 initializes the new quirk flag so gadget drivers can use it.
 	- AM335x PHY Driver learns about remote wakeup
 	- Renesas USBHS now requests DMA Engine only once
 	- s3c-hsotg is now re-used on Broadcom devices
 	- USB PHY layer now makes sure to initialize the notifier for all
 		drivers
 	- omap-control learned about TI's new AM437x devices
 	- few other usb gadget/function drivers learned about the new
 		configfs-based binding.
 
 Misc Fixes and Clean Ups:
 	- Several sparse fixes all over the place
 	- Removal of redundant of_match_ptr()
 	- r-car gen2 phy now uses usb_add_phy_dev()
 	- removal of DEFINE_PCI_DEVICE_TABLE() from a few drivers
 	- conversion to clk_prepare/clk_unprepare on r8a66597-udc
 	- some randconfig errors and build warnings were fixed
 	- removal of unnecessary lock on dwc3-omap.c

Robert Baldyga e117e742d3 usb: gadget: add "maxpacket_limit" field to struct usb_ep
This patch adds "maxpacket_limit" to struct usb_ep. This field contains
maximum value of maxpacket supported by driver, and is set in driver probe.
This value should be used by autoconfig() function, because value of field
"maxpacket" is set to value from endpoint descriptor when endpoint becomes
enabled. So when autoconfig() function will be called again for this endpoint,
"maxpacket" value will contain wMaxPacketSize from descriptior instead of
maximum packet size for this endpoint.

For this reason this patch adds new field "maxpacket_limit" which contains
value of maximum packet size (which defines maximum endpoint capabilities).
This value is used in ep_matches() function used by autoconfig().

Value of "maxpacket_limit" should be set in UDC driver probe function, using
usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function
set choosen value to both "maxpacket_limit" and "maxpacket" fields.

This patch modifies UDC drivers by adding support for maxpacket_limit.

Kuninori Morimoto 1b2e21b082 usb: renesas_usbhs: fifo: request DMAEngine once
DMAEngine uses IRQ if dma_request_channel() was called,
and it is using devm_request_irq() today,
OTOH, dma_request_channel() will be called when each
USB connection happened on this driver.
This means same IRQ will be requested many times
whenever each USB connected,
and this IRQ isn't freed when USB disconnected.
Request DMAEngine once.

finally getting rid of the old ->start()/->stop() methods
 in favor of the better and improved ->udc_start()/->udc_stop().
 
 There were surprisingly quite a few users left, but all of them
 have been converted.
 
 f_mass_storage removed some dead code, which is always great ;-)
 
 There's also a big cleanup to the gadget framework from Sebastian
 which gets us a lot closer to having only function drivers in
 kernel and move over to configfs-based binding.
 
 Other than these, there's the usual set of cleanups: s3c UDCs are
 moving over to devm_regulator_bulk_get() API, at91_udc removed
 an unnecessary check for work_pending() before scheduling and
 there's the removal of an unused variable from uac2_pcm_trigger().

Greg Kroah-Hartman 7fd94beeca 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.

Merge tag 'gadget-for-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

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."

Kuninori Morimoto 1c90ee0b3e usb: renesas_usbhs: use transfer counter if IN direction bulk pipe
received data will break if it was bulk pipe and large data size,
because pipe kept BUF PID even though it doesn't have enough buffer.
To avoid this issue, renesas_usbhs can use transfer counter.
Pipe PID will be NAK if it didn't have enough buffer by this patch.

renesas_usbhs has strange address mapping.
Thus, it is difficult to calculate transfer counter setting address.
This patch use fixed table for it.

Kuninori Morimoto 7b332e5fef usb: renesas_usbhs: host: add endpoint user counter
renesas_usbhs attaches pipe to endpoint when urb was queued, and it will be
detached when transfer was done.  Multi device controlling was enabled by this
behavior.

Now renesas_usbhs driver tried to wait until detaching if urb was queued to
endpoint which already has been attached to pipe, and it created strange driver
behavior.

But it can re-use this attached pipe if multi urb was queued.  This patch
implements it.
