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:
	- Keystone PHY driver and DWC3 Glue Layer
	- 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

usb: gadget: add "maxpacket_limit" field to struct usb_ep

2013-12-17T19:17:41+00:00

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.

usb: renesas_usbhs: fifo: request DMAEngine once

2013-12-12T19:43:34+00:00

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.

usb: hcd: move controller wakeup setting initialization to individual driver

2013-12-09T02:06:46+00:00

Individual controller driver has different requirement for wakeup
setting, so move it from core to itself. In order to align with
current etting the default wakeup setting is enabled (except for
chipidea host).

Pass compile test with below commands:
	make O=outout/all allmodconfig
	make -j$CPU_NUM O=outout/all drivers/usb

Remove GENERIC_HARDIRQ config option

2013-09-13T13:09:52+00:00

After the last architecture switched to generic hard irqs the config
options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code
for !CONFIG_GENERIC_HARDIRQS can be removed.

usb: renesas_usbhs: use platform_{get,set}_drvdata()

2013-08-28T04:35:23+00:00

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

usb: renesas: use dev_get_platdata()

2013-07-30T08:21:58+00:00

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

usb: renesas_usbhs: tidyup original usbhsx_for_each_xxx macro

2013-07-29T10:58:12+00:00

Current usbhsx_for_each_xxx macro will read out-of-array's
memory after last loop operation.
It was not good C language operation, and the binary which was
compiled by (at least) gcc 4.8.1 is broken
This patch tidyup these issues

usb: renesas_usbhs: gadget: remove extra check on udc_stop

2013-07-15T10:01:24+00:00

usb_gadget_ops :: udc_stop might be called with driver = NULL since
511f3c5326eabe1ece35202a404c24c0aeacc246
(usb: gadget: udc-core: fix a regression during gadget driver unbinding)

Because of that, 2nd times insmod goes fail.
This patch fixes it up.

USB: regroup all depends on USB within an if USB block

2013-04-09T23:49:07+00:00

This patch removes the depends on USB from all config symbols in
drivers/usb/host/Kconfig and replace that with an if USB / endif block
as suggested by Alan Stern. Some source ... Kconfig lines have been
shuffled around to permit a better regroupment of the Kconfig files
depending on "config USB" item. No functionnal change is introduced.
