git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc Pull main powerpc updates from Ben Herrenschmidt: "This time around, the powerpc merges are going to be a little bit more complicated than usual. This is the main pull request with most of the work for this merge window. I will describe it a bit more further down. There is some additional cpuidle driver work, however I haven't included it in this tree as it depends on some work in tip/timer-core which Thomas accidentally forgot to put in a topic branch. Since I didn't want to carry all of that tip timer stuff in powerpc -next, I setup a separate branch on top of Thomas tree with just that cpuidle driver in it, and Stephen has been carrying that in next separately for a while now. I'll send a separate pull request for it. Additionally, two new pieces in this tree add users for a sysfs API that Tejun and Greg have been deprecating in drivers-core-next. Thankfully Greg reverted the patch that removes the old API so this merge can happen cleanly, but once merged, I will send a patch adjusting our new code to the new API so that Greg can send you the removal patch. Now as for the content of this branch, we have a lot of perf work for power8 new counters including support for our new "nest" counters (also called 24x7) under pHyp (not natively yet). We have new functionality when running under the OPAL firmware (non-virtualized or KVM host), such as access to the firmware error logs and service processor dumps, system parameters and sensors, along with a hwmon driver for the latter. There's also a bunch of bug fixes accross the board, some LE fixes, and a nice set of selftests for validating our various types of copy loops.

2014-03-31watchdog: Fix Elan SC520 dependenciesJean Delvare1-1/+1
Anyone using a system based on an AMD Elan SC520 processor would be building a dedicated kernel for it, so we can make the sc520_wdt driver depend on MELAN. SC520_CPUFREQ already depends on MELAN so it makes things more consistent. It also makes kernel configuration for every other x86 user easier.

2014-03-31watchdog: it87_wdt: Work around non-working CIR interruptsMarc van der Wal1-10/+31
On some hardware platforms, the it87_wdt watchdog resets the machine despite the watchdog daemon running and writing to /dev/watchdog. This is due to Consumer IR buffer underrun interrupts being used as triggers to reset the timer. On some buggy hardware implementations such as the iEi AFL-12A-N270 single-board computer, this method does not work. However, resetting the timer by writing its original timeout value in its configuration register over and over again suppresses the unwanted reboots. Add a module option (nocir), 0 by default in order not to break existing setups. Setting it to 1 enables the workaround. Fixes bug #42801 <https://bugzilla.kernel.org/show_bug.cgi?id=42801>. Tested primarily on Linux 3.5.7, applies cleanly on Linux 3.13.5.

2014-03-20octeon, watchdog: Fix CPU hotplug callback registrationSrivatsa S. Bhat1-2/+9
Subsystems that want to register CPU hotplug callbacks, as well as perform initialization for the CPUs that are already online, often do it as shown below: get_online_cpus(); for_each_online_cpu(cpu) init_cpu(cpu); register_cpu_notifier(&foobar_cpu_notifier); put_online_cpus(); This is wrong, since it is prone to ABBA deadlocks involving the cpu_add_remove_lock and the cpu_hotplug.lock (when running concurrently with CPU hotplug operations). Instead, the correct and race-free way of performing the callback registration is: cpu_notifier_register_begin(); for_each_online_cpu(cpu) init_cpu(cpu); /* Note the use of the double underscored version of the API */ __register_cpu_notifier(&foobar_cpu_notifier); cpu_notifier_register_done(); Fix the watchdog code in octeon by using this latter form of callback registration.

2014-03-19watchdog: iTCO_wdt: Add support for v3 siliconPeter Tyser1-55/+82
Some new Atom's, eg Avoton and Bay Trail, have slightly different iTCO functionality: - The watchdog timer ticks at 1 second instead of .6 seconds - Some 8 and 16-bit registers were combined into 32-bit registers - Some registers were removed (DAT_IN, DAT_OUT, MESSAGE) - The BOOT_STS field in TCO_STS was removed - The NO_REBOOT bit is in the PMC area instead of GCS Update the driver to support the above changes and bump the version to 1.11.

2014-02-22watchdog: orion: Add support for Armada 370 and Armada XP SoCEzequiel Garcia1-2/+104
Using the added infrastructure for handling SoC differences, this commit adds support for the watchdog controller available in Armada 370 and Armada XP SoCs. Also, and because the AXP clock initialization uses of_clk_get_by_name, this commit changes the orion clock initialization to use clk_get() and adds a proper clk_put() on the common exit/error paths.
