Adapt vsp1_video_pipeline_run() such that it can iterate each partition required for constructing this frame's display list chain in the event that multiple display lists are required to process in hardware. The first display list is held as the head list object, whilst any following parition display lists are linked to the head by means of vsp1_dl_list_add_chain(). Linking the chained display list headers to process using the auto start mechanism of the hardware is performed during the vsp1_dl_list_commit().

2016-09-19[media] v4l: vsp1: Determine partition requirements for scaled imagesKieran Bingham5-0/+92
The partition algorithm needs to determine the capabilities of each entity in the pipeline to identify the correct maximum partition width. Extend the vsp1 entity operations to provide a max_width operation and use this call to calculate the number of partitions that will be processed by the algorithm. Gen 2 hardware does not require multiple partitioning, and as such will always return a single partition.

2016-09-19[media] v4l: vsp1: Support chained display listsKieran Bingham3-20/+102
When display lists are linked in a chain, they will be processed automatically by the hardware, with each list linking to the next. Only on the last display list will the frame end interrupt be fired to mark the completion event. Upon frame-end, the chain will be iterated to release each display list back to the free list. The chained lists use case (image partitioning) can require up to 64 lists per frame in the worst case scenario, bump up the number of preallocated lists.

2016-09-19[media] v4l: vsp1: Repair race between frame end and qbuf handlerKieran Bingham1-7/+2
The frame-end function releases and completes the buffers on the input and output entities of the pipe before marking the pipe->state as 'STOPPED'. This introduces a race whereby with the pipe->state still 'RUNNING', a QBUF handler can commence processing a frame before the frame_end function has completed. In the event that this happens, a frame queued by QBUF hangs due to the incorrect pipe->state setting which prevents vsp1_pipeline_run from issuing a CMD_STRCMD. By locking the entire function we prevent this from occurring, but we also change the locking state of the buffer release code. This has been analysed visually as acceptable, but it must be considered that this now causes the video->irqlock to be taken under the pipe->irqlock context.

2016-09-19[media] v4l: vsp1: Prevent pipelines from running when not streamingLaurent Pinchart1-0/+7
Pipelines can only be run if all their video nodes are streaming. Commit b4dfb9b35a19 ("[media] v4l: vsp1: Stop the pipeline upon the first STREAMOFF") fixed the pipeline stop sequence, but introduced a race condition that makes it possible to run a pipeline after stopping the stream on a video node by queuing a buffer on the other side of the pipeline. Fix this by clearing the buffers ready flag when stopping the stream, which will prevent the QBUF handler from running the pipeline.

2016-09-19MIPS: Octeon: Fix platform bus probingAaro Koskinen1-1/+1
Commit 44a7185c2ae6 ("of/platform: Add common method to populate default bus") added new arch_initcall of_platform_default_populate_init() that will override device_initcall octeon_publish_devices(). This broke many OCTEON boards as important devices are not getting probed anymore (e.g. on EdgeRouter Lite the USB mass storage/rootfs is missing). Fix by changing octeon_publish_devices() to arch_initcall.

2016-09-19MIPS: Octeon: mangle-port: fix build failure with VDSO codeAaro Koskinen1-2/+2
Commit 1685ddbe35cd ("MIPS: Octeon: Changes to support readq()/writeq() usage.") added bitwise shift operations that assume that unsigned long is always 64-bits. This broke the build of VDSO code, as it gets compiled also in "faked" 32-bit mode. Althought the failing inline functions are never executed in 32-bit mode, they still need to pass the compilation. Fix by using 64-bit types explicitly. The patch fixes the following build failure: CC arch/mips/vdso/gettimeofday-o32.o In file included from los/git/devel/linux/arch/mips/include/asm/io.h:32:0, from los/git/devel/linux/arch/mips/include/asm/page.h:194, from los/git/devel/linux/arch/mips/vdso/vdso.h:26, from los/git/devel/linux/arch/mips/vdso/gettimeofday.c:11: los/git/devel/linux/arch/mips/include/asm/mach-cavium-octeon/mangle-port.h: In function '__should_swizzle_bits': los/git/devel/linux/arch/mips/include/asm/mach-cavium-octeon/mangle-port.h:19:40: error: right shift count >= width of type [-Werror=shift-count-overflow] unsigned long did = ((unsigned long)a >> 40) & 0xff; ^~ Fixes: 1685ddbe35cd ("MIPS: Octeon: Changes to support readq()/writeq() usage.")

2016-09-19MIPS: Avoid a BUG warning during prctl(PR_SET_FP_MODE, ...)Marcin Nowakowski1-4/+4
cpu_has_fpu macro uses smp_processor_id() and is currently executed with preemption enabled, that triggers the warning at runtime. It is assumed throughout the kernel that if any CPU has an FPU, then all CPUs would have an FPU as well, so it is safe to perform the check with preemption enabled - change the code to use raw_ variant of the check to avoid the warning.

2016-09-19can: flexcan: fix resume functionFabio Estevam1-5/+8
On a imx6ul-pico board the following error is seen during system suspend: dpm_run_callback(): platform_pm_resume+0x0/0x54 returns -110 PM: Device 2090000.flexcan failed to resume: error -110 The reason for this suspend error is because when the CAN interface is not active the clocks are disabled and then flexcan_chip_enable() will always fail due to a timeout error. In order to fix this issue, only call flexcan_chip_enable/disable() when the CAN interface is active. Based on a patch from Dong Aisheng in the NXP kernel.
