Straight forward port of the VPFE driver from the 2.6.10 kernel,
including some previous work done by Alex Rier. There are a few things
which need cleanup before going upstream.

1) video-buf layer support for contiguous buffers
2) potential reuse of tvp5150 instead of tvp5146

For (2), if anyone is looking for a concrete way to contribute to the
open-source kernel, they could tackle it.  I haven't looked at the
datasheets in detail, but at first glance, I think we could probably
use the existing tvp5150 driver for the tvp5146 instead of adding a
new driver as the current.  The tvp5150 driver may need some minor
adjustments, but that is preferrable than having an entirely different
driver.

H4 board support now lists its tsc210x touchscreen/sensor/codec chip.
Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

This is mostly cleanup of the tsc210x patch, but some bugs were fixed so now
it works on tsc2101 too.  Also, a few issues are now noted in the code:

 Tool-reported:
  - Address checkpatch.pl issues in the original patch
  - And also "sparse" issues

 Previously wrong:
  - Cope with CONFIG_SOUND_MODULE
  - Register accessor routines will now return error codes
  - ... many callers now abort cleanly after errors
  - Don't depend on seeing only a rev #1 tsc2102 chip!
  - Add missing EXPORT_SYMBOL declarations

 Style issues:
  - BUG_ON() is strongly to be avoided
  - So are macros that capture variables
  - And needless casting from void pointers
  - And type punning
  - Use dev_*() for messaging where practical
  - Use u16 not uint16_t, etc
  - Various other whitespace issues
  - Avoid __FUNCTION__
  - Single-lines for file-top comments; no whole paths

 Object code size and Other cleanup:
  - Compile most strings out unless -DDEBUG is configured (saving space)
  - Move some code into exit sections (then it may well vanish, saving space)
  - Add some header comments

 Open issues:
  - Hwmon needs to know VREF and the chip type, and to scale its values
  - Upstream push should exclude audio until some version is working
  - Audio will needs to export symbols to modules, too
  - Lots of the I/O calls (especially audio) still don't handle errors
  - How could board init code get board-specific temp calibration data?

Also the Kconfig is more open-ended; tsc210x might in the future include the
tsc2100 and tsc2111, it doesn't need to be limited to tsc2101 and tsc2102.

Remove bogus TSC_IRQ pinmux; it's not used, there's no pin
dedicated for touchscreen (or other TSC chip) purposes, and
this doesn't even look right for P20 (0x10b not 0x108, plus
an IRQ would need to be a GPIO i.e. mux 3 not mux 0).

If musb_gadget_vbus_draw() also toggles a clock like tusb does,
USB clock will stay on after rmmoding a gadget driver. This
can block omap idle states.

Also handle disconnect as b_idle so that musb_gadget_vbus_draw()
gets called.
