* gpio: adp5588-gpio: add i2c forward declarationMichael Hennerich2010-10-27
| | | | | | | | | | | | Some ADP5588 functions take a pointer to an i2c_client, but if the i2c header doesn't happen to be included first, we hit the standard "struct declared inside parameter list" warnings from gcc. So add a simple forward decl of the i2c_client struct.

| | | | | | | | | | | | | | | | | | | | | | | The basic GPIO controllers may be found in various on-board FPGA and ASIC solutions that are used to control board's switches, LEDs, chip-selects, Ethernet/USB PHY power, etc. These controllers may not provide any means of pin setup (in/out/open drain).

* rtc: omap: let device wakeup capability be configured from chip init logicSekhar Nori2010-10-27
| | | | | | | | | | | | | | | | | | | | | | | | The rtc-omap driver currently hardcodes the RTC wakeup capability to be "not capable". While this seems to be true for existing OMAP1 boards which are not wired for this, the DA850/OMAP-L138 SoC, the RTC can always be wake up source from its "deep sleep" mode. This patch lets the wakeup capability be set from platform data and does not override the setting from the driver. For DA850/OMAP-L138, this is done from arch/arm/mach-davinci/devices-da8xx.c:da8xx_register_rtc() Note that this patch does not change the behavior on any existing OMAP1 board since the platform device registration sets the wakeup capability to 0 by default.

* mm: fix race in kunmap_atomic()Peter Zijlstra2010-10-27
| | | | | | | | | | | | | | | | | | | | | Christoph reported a nice splat which illustrated a race in the new stack based kmap_atomic implementation. The problem is that we pop our stack slot before we're completely done resetting its state -- in particular clearing the PTE (sometimes that's CONFIG_DEBUG_HIGHMEM). If an interrupt happens before we actually clear the PTE used for the last slot, that interrupt can reuse the slot in a dirty state, which triggers a BUG in kmap_atomic(). Fix this by introducing kmap_atomic_idx() which reports the current slot index without actually releasing it and use that to find the PTE and delay the _pop() until after we're completely done.

| | * drm/i915: Invalidate the to-ring, flush the old-ring when updating domainsChris Wilson2010-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the object has been written to by the gpu it remains on the ring until its flush has been retired. However, when the object is moving to the ring and the associated cache needs to be invalidated, we need to perform the flush on the target ring, not the one it came from (which is NULL in the reported case and so the flush was entirely absent).

| | * drm/i915/ringbuffer: Write the value passed in to the tail registerChris Wilson2010-10-22
| | | | | | | | | | | | | | | | | | | | | | | | This should fix the error along the reset path were we tried to clear the tail register by setting it to 0, but were in fact setting it to the current value and complaining when it did not reset to 0.

| | * drm/i915: Fix flushing regression from 9af90d19fChris Wilson2010-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whilst moving the code around in 9af90d19f, I dropped the or'ing in of new write domains which would zero out the write domain for a render target if later reused as a source later in the batch. This meant that we might drop a required flush before reading from the render target.

| | * i915: enable AVI infoframe for intel_hdmi.c [v4]David Härdeman2010-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the sending of AVI infoframes in drivers/gpu/drm/i915/intel_hdmi.c. My receiver currently loses sync when the HDMI output on my computer (DG45FC motherboard) is switched from 800x600 (the BIOS resolution) to 1920x1080 as part of the boot. Fixable by switching inputs on the receiver a couple of times. With this patch, my receiver has not lost sync yet (> 40 tries). Fourth version, now based on drm-intel-next from: git://git.kernel.org/pub/scm/linux/kernel/git/ickle/drm-intel.git Two questions still remain: I'm assuming that the sdvo hardware also stores a header ECC byte in the MSB of the first dword - is this correct? Does the SDVOB and SDVOC handling in intel_hdmi_set_avi_infoframe() look correct? Signed-off-by: David Härdeman <david@hardeman.nu> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
