All the clocks controlled by the register 'CCM Serial Clock Multiplexer Register 1' should be fixup clocks. This patch changes those clocks from basic multiplexer or divider clocks to fixup clocks. Signed-off-by: Liu Ying <Ying.Liu@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

Liu Ying authored
One register may have several fields to control some clocks. It is possible that the read/write values of some fields may map to different real functional values, so writing to the other fields in the same register may break a working clock tree. A real case is the aclk_podf field in the register 'CCM Serial Clock Multiplexer Register 1' of i.MX6Q/SDL SoC. This patch introduces a fixup hook for multiplexer clock which is called before writing a value to clock registers to support this kind of multiplexer clocks.

Pull qxl drm fixes from Dave Airlie: "Okay as I warned, the qxl driver was running a bit free and loose with its ttm object reservations and the new lockdep enabled reservation tracking shone a bright light into it, it also with the new reservations mutexes hits a possible deadlock during boot. The first patch is a real fix to render the console correctly as the driver used to just drop irq renderering as too hard, this also fixes a sleeping while atomic warning. The other two patches are the big ugly ones that redo how the driver allocates objects and reserves them and makes things all work properly, I've tested this in a VM, and compared to the current code which hits a lockdep warning and the sleep while atomic warning before failing. So sorry this is coming in late, I should have tested qxl before merging the mutex code, but I'd rather just fix qxl with this than revert the reservations code at this point" * 'qxl-fixes' of git://people.freedesktop.org/~airlied/linux: qxl: convert qxl driver to proper use for reservations qxl: allow creation of pre-pinned objects and use for releases. drm/qxl: add delayed fb operations

Rafael J. Wysocki authored
We attempted to address a regression introduced by commit a57f7f91 (ACPICA: Add Windows8/Server2012 string for _OSI method.) after which ACPI video backlight support doesn't work on a number of systems, because the relevant AML methods in the ACPI tables in their BIOSes become useless after the BIOS has been told that the OS is compatible with Windows 8. That problem is tracked by the bug entry at: https://bugzilla.kernel.org/show_bug.cgi?id=51231 Commit 8c5bd7ad (ACPI / video / i915: No ACPI backlight if firmware expects Windows 8) introduced for this purpose essentially prevented the ACPI backlight support from being used if the BIOS had been told that the OS was compatible with Windows 8 and the i915 driver was loaded, in which case the backlight would always be handled by i915. Unfortunately, however, that turned out to cause problems with backlight to appear on multiple systems with symptoms indicating that i915 was unable to control the backlight on those systems as expected. For this reason, revert commit 8c5bd7ad, but leave the function acpi_video_backlight_quirks() introduced by it, because another commit on top of it uses that function.

Commit a8227415 "tracing: Protect ftrace_trace_arrays list in trace_events.c" added taking the trace_types_lock mutex in trace_events.c as there were several locations that needed it for protection. Unfortunately, it also encapsulated a call to tracing_reset_all_online_cpus() which also takes the trace_types_lock, causing a deadlock. This happens when a module has tracepoints and has been traced. When the module is removed, the trace events module notifier will grab the trace_types_lock, do a bunch of clean ups, and also clears the buffer by calling tracing_reset_all_online_cpus. This doesn't happen often which explains why it wasn't caught right away. Commit a8227415 was marked for stable, which means this must be sent to stable too.
