We'd better place clock set-up in dc as HDMI. It makes code cleaner. Also eliminate a false warning.

2011-12-15tegra: fb: HDMI monitor spec. not correct via "mode" device.Andre Sihera
When monitor is auto-detected on HDMI port, a special structure is initialised to hold the video mode properties for the plugged- in monitor. From this the display string is generated for displa via the "mode" character device under /sys. When the monitor is disconnected, the structures associated with the monitor tself are cleared, but the pointer to the video mode properties structure was left initialised and so pointed into thin air, which resulted in garbage appearing on the "mode" device. Added explicit deinitialisation code to reset pointer to video mode properties so "cat mode" within /sys yields an empty string when the HDMI monitor is unplugged.

2011-12-09oprofile: Fix crash when unloading module (hr timer mode)Robert Richter
commit 87121ca504fd1d963a66b3fb0c72054b0fd9a177 upstream. Oprofile may crash in a KVM guest while unlaoding modules. This happens if oprofile_arch_init() fails and oprofile switches to the hr timer mode as a fallback. In this case oprofile_arch_exit() is called, but it never was initialized properly which causes the crash. This patch fixes this. oprofile: using timer interrupt.

2011-12-09rtc: Fix some bugs that allowed accumulating time drift in suspend/resumeArve Hjønnevåg
commit 6a8943d9ec2567572fca25cf69ad45844d0141a3 upstream. The current code checks if abs(delta_delta.tv_sec) is greater or equal to two before it discards the old delta value, but this can trigger at close to -1 seconds since -1.000000001 seconds is stored as tv_sec -2 and tv_nsec 999999999 in a normalized timespec. rtc_resume had an early return check if the rtc value had not changed since rtc_suspend. This effectivly stops time for the duration of the short sleep. Check if sleep_time is positive after all the adjustments have been applied instead since this allows the old_system adjustment in rtc_suspend to have an effect even for short sleep cycles.

However, we do need mac80211 to create the MMIC & PN in all cases. Move the code around to set the key flags all the time.

2011-12-09xHCI: fix bug in xhci_clear_command_ring()Andiry Xu
commit 158886cd2cf4599e04f9b7e10cb767f5f39b14f1 upstream. When system enters suspend, xHCI driver clears command ring by writing zero to all the TRBs. However, this also writes zero to the Link TRB, and the ring is mangled. This may cause driver accesses wrong memory address and the result is unpredicted. When clear the command ring, keep the last Link TRB intact, only clear its cycle bit. This should fix the "command ring full" issue reported by Oliver Neukum. This should be backported to stable kernels as old as 2.6.37, since the commit 89821320 "xhci: Fix command ring replay after resume" is merged.

2011-12-09USB: EHCI: fix HUB TT scheduling issue with iso transferThomas Poussevin
commit 811c926c538f7e8d3c08b630dd5844efd7e000f6 upstream. The current TT scheduling doesn't allow to play and then record on a full-speed device connected to a high speed hub. The IN iso stream can only start on the first uframe (0-2 for a 165 us) because of CSPLIT transactions. For the OUT iso stream there no such restriction. uframe 0-5 are possible. The idea of this patch is that the first uframe are precious (for IN TT iso stream) and we should allocate the last uframes first if possible. For that we reverse the order of uframe allocation (last uframe first). Here an example : hid interrupt stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ---------------------------------------------------------------------- iso OUT stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 125 | 39 | 0 | 0 | 0 | 0 | 0 | ---------------------------------------------------------------------- There no place for iso IN stream (uframe 0-2 are used) and we got "cannot submit datapipe for urb 0, error -28: not enough bandwidth" error. With the patch this become. iso OUT stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 0 | 0 | 125 | 39 | 0 | 0 | ---------------------------------------------------------------------- iso IN stream ---------------------------------------------------------------------- uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | ---------------------------------------------------------------------- max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 | ---------------------------------------------------------------------- used usecs on a frame | 13 | 0 | 125 | 40 | 125 | 39 | 0 | 0 | ---------------------------------------------------------------------- Signed-off-by: Matthieu Castet <matthieu.castet@parrot.com> Signed-off-by: Thomas Poussevin <thomas.poussevin@parrot.com> Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

commit 5d193ce8f1fa7c67c7fd7be2c03ef31eed344a4f upstream. Currently the driver tries to save context in the suspend path, but will cause an abort if the device is already runtime suspended. This happens, for example, if MUSB loaded/compiled-in, in host mode, but no USB devices are attached. MUSB will be runtime suspended, but then attempting a system suspend will crash due to the context save being attempted while the device is disabled. On OMAP, as of v3.1, the driver's ->runtime_suspend() callback will be called late in the suspend path (by the PM domain layer) if the driver is not already runtime suspended, ensuring a full shutdown. Therefore, the context save is not needed in the ->suspend() method since it will be called in the ->runtime_suspend() method anyways (similarily for resume.) NOTE: this leaves the suspend/resume methods basically empty (with some FIXMEs and comments, but I'll leave it to the maintainers to decide whether to remove them.

2011-12-09regulator: twl: fix twl4030 support for smps regulatorsTero Kristo
commit ba305e31e88ea5c2f598ff9fbc5424711a429e30 upstream. SMPS regulator voltage control differs from the one of the LDO ones. Current TWL code was using LDO regulator ops for controlling the SMPS regulators, which fails. This was fixed fixed by adding separate regulator type which uses correct logic and calculations for the voltage levels.

2011-12-09regulator: aat2870: Fix the logic of checking if no id is matched in ↵Axel Lin
aat2870_get_regulator commit d4d6373c1109b11c8118340be97ae31b8f94d66a upstream. In current implementation, the pointer ri is not NULL if no id is matched. Fix it by checking i == ARRAY_SIZE(aat2870_regulators) if no id is matched.
