      musb_hdrc: fix some bugs in the updated host side code · 23da5183
      David Brownell authored 
       - 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.

      musb_hdrc: cleanup, mostly related to CPPI · e9b7cce8
      David Brownell authored 
       - Remove #ifdefs in favor of new is_cppi_enabled() macro.
 - Trim some tx-start logic, inlining it and removing MGC_{Read,Write}Csr16()
 - Remove remnant of bogus/non-existent host-side ISO bitfield.

For upstream merging, more such #ifdeffery still needs to be removed.

      musb_hdrc: DaVinci-specific updates and cleanups · 5261debe
      David Brownell authored 
       - Add header needed for DaVinci build.
 - Remove some partially obsolete comments.
 - Cleaner and more reproducible host side VBUS handling, including
   waiting for it to fall after powerdown on rmmod.
 - Tighten up various state machine transitions and diagnostics

Plus removing some generic #ifdeffery.  The vbus updates make it work more like
the TUSB code, and the cleanups etc make upstream merging more practical.

      musb_hdrc: add heuristic to make ethernet peripherals use RNDIS RX mode · 652bfff7
      David Brownell authored 
      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.

      [PATCH] ARM: OMAP: Palm Tungsten E board update · 64688c2d
      andrzej zaborowski authored 
      General update of the board file for Palm Tungsten E. Registers the
platform devices contained in the PDA (ROM chip, keypad, infra-red)
and updates the configuration for USB and MMC, whose config values
were previously guessed in most cases due to lack of documentation
(and now are confirmed by a number of users). Macros for GPIO pins are
moved to a file in include/asm-arm/arch-omap.

      [PATCH] ARM: OMAP: correct misc 15xx and non-15xx platform code · 67755f3e
      andrzej zaborowski authored 
      Disable accesses to SOFT_REQ_REG2 and ULPD_SOFT_DISABLE_REQ_REG
registers for 15xx processors that don't have these registers. Enable
level 2 interrupt handler for processors that identify as OMAP 15xx
(e.g 310) and not 1510 specifically. Also fix the following compiler
warning (only visible with CONFIG_OMAP_RESET_CLOCKS):

arch/arm/mach-omap1/clock.c: In function 'omap1_clk_disable_unused':
arch/arm/mach-omap1/clock.c:634: warning: 'return' with a value, in
function returning void
