Pull GPIO driver changes from Grant Likely: "Lots of gpio changes, both to core code and drivers. Changes do touch architecture code to remove the need for separate arm/gpio.h includes in most architectures. Some new drivers are added, and a number of gpio drivers are converted to use irq_domains for gpio inputs used as interrupts. Device tree support has been amended to allow multiple gpio_chips to use the same device tree node. Remaining changes are primarily bug fixes." * tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6: (33 commits) gpio/generic: initialize basic_mmio_gpio shadow variables properly gpiolib: Remove 'const' from data argument of gpiochip_find() gpio/rc5t583: add gpio driver for RICOH PMIC RC5T583 gpiolib: quiet gpiochip_add boot message noise gpio: mpc8xxx: Prevent NULL pointer deref in demux handler gpio/lpc32xx: Add device tree support gpio: Adjust of_xlate API to support multiple GPIO chips gpiolib: Implement devm_gpio_request_one() gpio-mcp23s08: dbg_show: fix pullup configuration display Add support for TCA6424A gpio/omap: (re)fix wakeups on level-triggered GPIOs gpio/omap: fix broken context restore for non-OFF mode transitions gpio/omap: fix missing check in *_runtime_suspend() gpio/omap: remove cpu_is_omapxxxx() checks from *_runtime_resume() gpio/omap: remove suspend/resume callbacks gpio/omap: remove retrigger variable in gpio_irq_handler gpio/omap: remove saved_wakeup field from struct gpio_bank gpio/omap: remove suspend_wakeup field from struct gpio_bank gpio/omap: remove saved_fallingdetect, saved_risingdetect gpio/omap: remove virtual_irq_start variable ...

Pull main drm updates from Dave Airlie: "This is the main merge window request for the drm. It's big, but jam packed will lots of features and of course 0 regressions. (okay maybe there'll be one). Highlights: - new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus (qemu only). These drivers use the generic modesetting drivers. - initial prime/dma-buf support for i915, nouveau, radeon, udl and exynos - switcheroo audio support: so GPUs with HDMI can turn off the sound driver without crashing stuff. - There are some patches drifting outside drivers/gpu into x86 and EFI for better handling of multiple video adapters in Apple Macs, they've got correct acks except one trivial fixup. - Core: edid parser has better DMT and reduced blanking support, crtc properties, plane properties, - Drivers: exynos: add 2D core accel support, prime support, hdmi features intel: more Haswell support, initial Valleyview support, more hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of cleanups and fixes radeon: more HDMI audio support, improved GPU lockup recovery support, remove nested mutexes, less memory copying on PCIE, fix bus master enable race (kexec), improved fence handling gma500: cleanups, 1080p support, acpi fixes nouveau: better nva3 memory reclocking, kepler accel (needs external firmware rip), async buffer moves on nv84+ hw. I've some more dma-buf patches that rely on the dma-buf merge for vmap stuff, and I've a few fixes building up, but I'd decided I'd better get rid of the main pull sooner rather than later, so the audio guys are also unblocked."

Pull more networking updates from David Miller: "Ok, everything from here on out will be bug fixes." 1) One final sync of wireless and bluetooth stuff from John Linville. These changes have all been in his tree for more than a week, and therefore have had the necessary -next exposure. John was just away on a trip and didn't have a change to send the pull request until a day or two ago. 2) Put back some defines in user exposed header file areas that were removed during the tokenring purge. From Stephen Hemminger and Paul Gortmaker. 3) A bug fix for UDP hash table allocation got lost in the pile due to one of those "you got it.. no I've got it.." situations. :-) From Tim Bird. 4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll try to coalesce overlapping frags and crash. Fix from Eric Dumazet. 5) RCU routing table lookups can race with free_fib_info(), causing crashes when we deref the device pointers in the route. Fix by releasing the net device in the RCU callback.

2012-05-24Input: matrix-keymap - fix building keymapsDmitry Torokhov
Keymaps used by drivers based on matrix-keymap facilities are arrays of unsigned shorts, not chars. Treating them otherwise produces corrupted keymaps. Reported-by: Sourav Poddar <sourav.poddar@ti.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2012-05-24drm/nouveau: Unregister switcheroo client on exitAndreas Heider
Currently nouveau only registers as a vga_switcheroo client, but never unregisters. This patch adds the necessary unregister calls. Signed-off-by: Andreas Heider <andreas@meetr.de> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-05-24drm/nouveau: Check dsm on switcheroo unregisterAndreas Heider
Currently vga_switcheroo_unregister_handler is called unconditionally when nouveau is unloaded, even when nouveau never registered a handler. This interferes with other switcheroo handlers, as vga_switcheroo doesn't check who called unregister_handler, but simply unregisters the current handler. This patch adds a check so unregister is only called if a handler was registered by nouveau before. Signed-off-by: Andreas Heider <andreas@meetr.de> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-05-24drm/nouveau/fifo: turn all fifo modules into engine modulesBen Skeggs
Been tested on each major revision that's relevant here, but I'm sure there are still bugs waiting to be ironed out. This is a *very* invasive change. There's a couple of pieces left that I don't like much (eg. other engines using fifo_priv for the channel count), but that's an artefact of there being a master channel list still. This is changing, slowly. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-05-24drm/nouveau/fifo: remove all the "special" engine hooksBen Skeggs
All the places this stuff is actually needed tends to be chipset-specific anyway, so we're able to just inline the register bashing instead. The parts of the common code that still directly touch PFIFO temporarily have conditionals, these will be removed in subsequent commits that will refactor the fifo modules into engine modules like graph/mpeg etc. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

Just a cleanup more or less, and to remove the need for special handling of software objects. This removes a heap of documentation on dma/graph object formats.

2012-05-24drm/nvd0/disp: remove unnecessary sync from flip_nextBen Skeggs
This shouldn't be necessary, I believe this is just a bit of missed debug code that got left over somehow. Causes flips to be always synced to vblank, regardless of swap interval, which we don't want.. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
