[Patch v6 00/12] Add MFC v10.10 support

This patch series adds MFC v10.10 support. MFC v10.10 is used in some of Exynos7 variants. This adds support for following: * Add support for HEVC encoder and decoder * Add support for VP9 decoder * Update Documentation for control id definitions * Update computation of min scratch buffer size

[PATCH v5 1/7] scsi: libsas: Use dynamic alloced work to avoid sas event lost

Now libsas hotplug work is static, every sas event type has its own static work, LLDD driver queues the hotplug work into shost->work_q. If LLDD driver burst posts lots hotplug events to libsas, the hotplug events may pending in the workqueue like shost->work_q new work[PORTE_BYTES_DMAED] -->

[PATCH v5 2/7] scsi: libsas: shut down the PHY if events reached the threshold

If the PHY burst too many events, we will alloc a lot of events for the worker. This may leads to memory exhaustion. Dan Williams suggested to shut down the PHY if the events reached the threshold, because in this case the PHY may have gone into some erroneous state. Users can re-enable the PHY

[PATCH v5 3/7] scsi: libsas: make the event threshold configurable

[PATCH v5 0/7] Enhance libsas hotplug feature

When the Hfplls are reprogrammed during the rate change, the primary muxes which are sourced from the same hfpll for higher frequencies, needs to be switched to the 'safe secondary mux' as the parent for that small window. This is done by registering a clk notifier for the muxes and switching to
