I seem to have a knack for digging up buggy usb devices which don't work
with Linux, and I'm crazy enough to try to make them work. So this time a
friend of mine asked me to get an mp4 player (an mp3 player which can play
videos on a small screen) to work with Linux.
It is based on the well known rockbox chipset for which we already have an
unusual devs entries to work around some of its bugs. But this model
comes with an additional twist.
This model chokes on read_capacity_16 calls. Now normally we don't make
those calls, but this model comes with an sdcard slot and when there is no
card in there (and shipped from the factory there is none), it reports a
size of 0. However this time the programmers actually got the
read_capacity_10 response right! So they substract one from the size as
stored internally in the mp3 player before reporting it back, resulting in
an answer of ... 0xffffffff sectors, causing sd.c to try a
read_capacity_16, on which the device crashes.
This patch adds a flag to scsi_device to indicate that a a device cannot
handle read_capacity_16, and when this flag is set if a device reports an
lba of 0xffffffff as answer to a read_capacity_10, assumes it tries to
report a size of 0.

Some USB devices emulate a usb-mass-storage attached (scsi) cdrom device,
usually this fake cdrom contains the windows software for the device.
While working on supporting Appotech ax3003 based photoframes, which do
this I discovered that they will go of into lala land when ever they see a
READ_DISC_INFO scsi command.
Thus this patch adds a scsi_device flag (which can then be set by the
usb-storage driver through an unsual-devs entry), to indicate this, and
makes the sr driver honor this flag.
I know this sucks, but as discussed on linux-scsi list there is no other
way to make this device work properly.
Looking at usb traces made under windows, windows never sends a
READ_DISC_INFO during normal interactions with a usb cdrom device. So as
this cdrom emulation thingie becomes more common we might see more of this
problem.

Extends FSL EHCI platform driver glue layer to support
MPC5121 USB controllers. MPC5121 Rev 2.0 silicon EHCI
registers are in big endian format. The appropriate flags
are set using the information in the platform data structure.
MPC83xx system interface registers are not available on
MPC512x, so the access to these registers is isolated in
MPC512x case. Furthermore the USB controller clocks
must be enabled before 512x register accesses which is
done by providing platform specific init callback.
The MPC512x internal USB PHY doesn't provide supply voltage.
For boards using different power switches allow specifying
DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal
PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault"
properties in the device tree USB nodes. Adds documentation

The iManufatcurer, iProduct and iSerialNumber composite module
parameters were only used when the gadget driver registers
strings for manufacturer, product and serial number. If the
gadget never bothered to set corresponding fields in USB device
descriptors those module parameters are ignored.
This commit makes the parameters work even if the strings ID
have not been assigned. It also changes the way IDs are
overridden -- what IDs are overridden is now saved in
usb_composite_dev structure -- which makes it unnecessary to
modify the string tables the way previous code did.
The commit also adds a iProduct and iManufatcurer fields to the
usb_composite_device structure. If they are set, appropriate
strings are reserved and added to device descriptor. This makes
it unnecessary for gadget drivers to maintain code for setting
those. If iProduct is not set it defaults to
usb_composite_device::name; if iManufatcurer is not set
a default "<system> <release> with <gadget-name>" is used.
The last thing is that if needs_serial field of
usb_composite_device is set and user failed to provided
iSerialNumber parameter a warning is issued.

Simply add an early_altera_uart_setup() prototype declaration, otherwise
platform code have to do it in .c files, which is ugly.

Some controllers implement registers with a stride, to support
those we must implement the proper IO accessors.

Soon we will use that handy function in the altera_uart driver.

A notifier chain is called whenever the vt code modifies a terminal
content, except for one case which is when the modification comes
through writes to /dev/vcs* devices. Let's add the missing notifier
invocation at the end of vcs_write() for that case too.

Dan Rosenberg noted that various drivers return the struct with uncleared
fields. Instead of spending forever trying to stomp all the drivers that
get it wrong (and every new driver) do the job in one place.
This first patch adds the needed operations and hooks them up, including
the needed USB midlayer and serial core plumbing.

This patch converts cris to use asm-generic/ioctls.h instead of its
own version.
The differences between the arch-specific version and the generic
version are as follows:
- CRIS defines two ioctls: TIOCSERSETRS485 and TIOCSERWRRS485,
kept in arch-specific portion
- CRIS defines a different value for TIOCSRS485, kept via ifndef in generic
- The generic version adds support for termiox

This patch removes __GFP_NOFAIL use from tty_add_file() and adds proper error
handling to the call-sites of the function.
