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.

Tighten up error handling in the procfs dump, and avoid returning bogus values from the read() system call. Report single vs double buffering for FIFO setup. Signed-off-by:David Brownell <dbrownell@users.sourceforge.net>

- 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. Signed-off-by: -

- 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. Signed-off-by: -

- 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. Signed-off-by: -

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. Signed-off-by: -

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. Signed-off-by:

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 Signed-off-by:

Here's the patch that updates DSP Gateway driver to 3.3.1, that supports omap2 DSP. It also contains generic mailbox interface considering IVA use on 2420, but this patch itself doesn't contain any IVA driver. Regarding omap2, this code is tested only on our 2420 custom board, so feedbacks from testing on other chips / boards will be greatly appreciated. Signed-off-by:
