use_dma parameter was designed to enable the dma on the chip. It was
enabled by default.
It comes from the time when the dma was not reliable. Now it has been
working ok in production.
This patch removes this parameter.

Parameter use_msi was used to enable msi irq on usb338x chips, it was
enabled by default.
There is no reason to prefer non-msi irq on usb338x, and it falls back
to non msi on error.
Therefore remove this option.

This patch removes the full_speed parameter used force full-speed
operation.
It was designed exclusively for testing purposes, and there is no
reason to maintain this in a production kernel.

use_dma_chaining module parameter was designed to avoid creating one irq
per package on a group of packages (with the help of the driver's flag
no_interrupt).
Unfortunately, when this parameter is enabled, the driver fails to work
on both net2280 and 3380 chips.
This patch removes this parameter, which was disabled by default.

The EHCI controller on the RK3288 SoC is violating basic parts of the
USB spec and thereby unable to properly resume a suspended port. It does
not start SOF generation within 3ms of finishing resume signaling, so
the attached device will drop of the bus again. This is a particular
problem with runtime PM, where accessing the device will trigger a
resume that immediately makes it unavailable (and reenumerate with a new
handle).
Thankfully, the persist feature is generally able to work around stuff
like that. Unfortunately, it doesn't quite work in this particular case
because the controller will turn off the CurrentConnectStatus bit for an
instant while the device is reconnecting, which causes the kernel to
conclude that it permanently disappeared. This patch adds a tiny retry
mechanism to the core port resume code which will catch this case and
shouldn't have any notable impact on other controllers.

The PPC_OF is a ppc specific option which is used to mean that the
firmware device tree access functions are available. Since all the
ppc platforms have a device tree, it is aways set to 'y' for ppc.
So it makes no sense to keep a such option in the current kernel.
Replace it with PPC

This is a follow up to the previously submitted commit cefa9a31a5f0 (ehci-pci:

It includes the following changes:
- table and function are renamed to reflect this is not only about ChipIdea
- ChipIdea PCI driver (ci_hdrc_pci.c) gets the comment about the table in
ehci-pci.c
- MIPS IDs removed from the list since it was discovered and tested on Intel
MID platforms

The usb_hcd_unlink_urb() routine in hcd.c contains two possible
use-after-free errors. The dev_dbg() statement at the end of the
routine dereferences urb and urb->dev even though both structures may
have been deallocated.
This patch fixes the problem by storing urb->dev in a local variable
(avoiding the dereference of urb) and moving the dev_dbg() up before
the usb_put_dev() call.

Currently the USB stack assumes that all host controller drivers are
capable of receiving wakeup requests from downstream devices.
However, this isn't true for the isp1760-hcd driver, which means that
it isn't safe to do a runtime suspend of any device attached to a
root-hub port if the device requires wakeup.
This patch adds a "cant_recv_wakeups" flag to the usb_hcd structure
and sets the flag in isp1760-hcd. The core is modified to prevent a
direct child of the root hub from being put into runtime suspend with
wakeup enabled if the flag is set.

The usbfs API has a peculiar hole: Users are not allowed to reap their
URBs after the device has been disconnected. There doesn't seem to be
any good reason for this; it is an ad-hoc inconsistency.
The patch allows users to issue the USBDEVFS_REAPURB and
USBDEVFS_REAPURBNDELAY ioctls (together with their 32-bit counterparts
on 64-bit systems) even after the device is gone. If no URBs are
pending for a disconnected device then the ioctls will return -ENODEV
rather than -EAGAIN, because obviously no new URBs will ever be able
to complete.
The patch also adds a new capability flag for
USBDEVFS_GET_CAPABILITIES to indicate that the reap-after-disconnect
feature is supported.

There is old, unused code that is #defined out by the use of NOTMOS7840
and NOTMCS7840 - these are not defined anywhere.
If NOTMOS7840 is defined then the code will break on null pointer
dereferences on mos7840_port. So the code is currently unused, and
broken anyway, so why not just remove it.

This device needs to be continuously clocked to provide wake up support,
previously, if STANDBY target were chosen the device were
enable_irq_wake()-prepared and clock still active and if MEM target were
chosen the device were also enable_irq_wake()-prepared but not clocked
anymore, which is wrong.
Now, if STANDBY target is chosen the device is still clocked with wake
up support enabled, which were the previous default and if MEM target is
chosen the device is declocked with wake up support disabled.

This patch add suspend/resume support for Atmel EHCI, mostly
about disabling and unpreparing clocks so USB PLL is stopped
before entering sleep state.

Currently if port power is turned off by user on hub port
using USBDEVFS then port power is turned back ON
by hub driver.
This commit modifies hub reset logic in hub_port_connect() to prevent
hub driver from turning back the port power ON if port is not owned
by kernel.
