2013-07-10ENGR00265414-8 mxc: asrc: Improve channel setting interfaceNicolin Chen
ASRC driver allows users to set channel number via PROC interface, but only passes the total number equal 10. This's not reasonable because ASRC can use total number lower than 10 if user assure each of them is an even number.

2013-07-10ENGR00255920-2 mxc vout:wait for 2 vsyncs when streamoffLiu Ying
Some expiring video buffers may have been rendered to display triple buffers for display. The relevant triple buffers are set to be ready and depend on the display hardware engine to switch them to be active on screen in turn automatically. So, we need to wait for at least 2 vsyncs to make sure all of the expiring video buffers be shown on display already.

2013-07-10ENGR00255920-1 mxc vout:Remove cancel_work_sync() when streamoffLiu Ying
We hope the queued works can be done before streamoff, since the works will render expiring video buffers to display. But, the function cancel_work_sync() cannot guarantee this. Instead, it may cancel some queued works before they starts to work. This patch removes the function call cancel_work_sync() when streamoff. We rely on the function flush_workqueue() right after it to make sure queued works be done before streamoff.

2013-07-09ENGR00270045: thermal: Add timeout for temperature updateAnson Huang
Need to add timeout for temperature update, otherwise, if suspend comes during thermal sensor measurement, its power will be turned off, and after resume, the delay work thread will never get finish flag and result in thread forever loop, temperature will never get updated. And if we wait for the measurement finish before suspend, the time is too long for suspend, as one single measurement would take as long as 100ms which is not good for suspend, so just add a timeout.

2013-06-14ENGR00266881 mxc vout:Flush workqueue when change is needed for streamingLiu Ying
We currently call cancel_work_sync() to have all left work be done. But, this is not safe to make sure all left work being done successfully. Instead, chances are that some work may be cancelled before starting to be done, which may cause frame lost and make us hang at upcoming wait_event_interruptible() in videobuf_waiton() called from video buffer core v1 framework's dqbuf API. This patch replaces the function call cancel_work_sync() with flush_workqueue() to fix the issue. Signed-off-by: Liu Ying <Ying.Liu@freescale.com>

Users may call VIDIOC_S_CTRL ioctrl to do rotation, such as 90 degree rotation, when a video is streaming in IC bypass mode. The runtime rotation setting may make the vout driver lose the track for a previous video buffer and finally cause the streaming hang.

2013-05-22ENGR00263304-3 IPUv3:Check NULL irq handler in ipu_request_irq()Liu Ying
To avoid NULL interrupt handler being called potentially in the IPU sync interrupt source handler, this patch adds sanity check on NULL interrupt handler in the function ipu_request_irq() for sync interrupts because the callers are likely to request a sync interrupt without specifying a handler. The error interrupts can still be enabled by this function without this kind of sanity check since we simply print out the relevant error interrupt register values in the IPU error interrupt source's handler. This patch also corrects _ipu_get() and _ipu_put() function call in the function ipu_request_irq() to make them be called in pair when handler has already been registered.
