ALSA driver for OMAP boards with a TSC2102 chip. It is based on the
TSC2101 and AIC23 drivers. The chip has only one audio playback output
and no inputs. It can play stereo sound with 16-bit samples (only) and
supports different sampling rates between 8 and 48 kHz. The patch also
includes an ALSA mixer. The mixer controlls two volume levels, for
left and right channels, each with 128 steps. It can also toggle the
analog de-emphasis filter and bass boost filter which are incorporated
in the chip.

In addition to that the chip has an equaliser filter, but the mixer
doesn't use it because the coefficients of the filter are difficult to
map to other values used in normal equalisers. Maybe they should have
constant values per board.

This adds a driver for the TSC2102 chip by Texas Instruments. This
driver is responsible for all communication with the chip and doesn't
export anything for user-space, but for other drivers controlling
devices connected to the chip.

GPMC updates:
 - bugfixes: wrong/missing flags, omitted write, wrong test
 - don't map memory segments starting at zero
 - improve debug messaging
 - export gpmc_get_fclk_perio]d() since it's needed to calc timings
 - expect gpmc_cs_set_timings() caller to have initialized sync vs async

Note that this API is glitchy; likely the best fix would be to add
a member to "struct gpmc_timings" to hold GPMC_CONFIG1, since that
holds one key aspect of the GPMC timings (the gpmc_fclk divisor,
and sync vs. async == whether that divisor matters).

If there is a signal pending and wait_for_completion_interruptible_timeout
terminates with -ERESTARTSYS, we return and disable the i2c clocks in
omap_i2c_xfer.

If we terminate before sending last i2c message with a stop condition, the
bus remains busy and we are not able to send new messages into bus with
successive omap_i2c_xfer calls. Therefore a pending signal is not caught
here and we return only because of timeout or i2c error.

Updating system time and reprogramming timer can cause latency
issues on busy systems with lots of interrupts with constant
updating of time and reprogramming the system timer.

If a non-timer dyntick interrupt happens within a jiffy from
the last interrupt, updating time and reprogramming the timer
is unnecessary as we will get a timer interrupt soon anyways.

 - Remove an oops in the queue fault cleanup path, caused by using the
   wrong giveback routine (heavy weight vs lighter-weight).  Move a few
   key bits of code into that lighter weight version.

 - Trigger that lighter-weight cleanup during URB completion, when the
   URB in question can't yet been handed off to the hardware even if
   it's at the queue head.

 - Reduce syslog noise when those fault cleanup paths are triggered from
   scatterlist calls by usb-storage.

 - Paranoia: when scheduling, insist that the endpoint fifo isn't smaller
   than required.

Oops observed courtesy of a slightly flakey usb-storage device, which
once again proves itself handy for testing.

When you're willing to trust the USB host not to commit certain errors, the
CPPI "rndis" RX mode can be used with the peripheral side g_ether driver.
(In other cases, rndis rx mode tends to misbehave _very_ rudely ...)

This patch adds a heuristic to detect when the safe scenario is likely, and
a module parameter to disable the heuristic in contexts when it's likely
to fail; for example, users of gadgetfs will likely need to disable it.

This gave about a 60% improvement in throughput with CDC Ethernet (!!) and a
slight reduction in CPU load.  That's measured with TTCP, which pushes a lot
of full size Ethernet frames and thus can see three IRQs per packet reduced
to just one, and also get I/O overlap when double buffering packets.  That is,
net 10 MByte/sec sustained, using double buffering but no DMA transfer queues;
it's unclear why TX is still just 6 MByte/sec.
