Change compared to v8:
-change commit message of patch 02/18
-use pm_runtime_put() to replace pm_runtime_put_sync() of patch 05/18
-add one patch for deletting the resetting hardware flow in the system PM ops
-use v4l2_m2m_suspend() and v4l2_m2m_resume() to improve the implemention
of the system PM ops. This patch(07/18) depends on [RFC,V4,1/4] media:
v4l2_mem2mem: add v4l2_m2m_suspend, v4l2_m2m_resume(https://patchwork.kernel.org/patch/11272917/)
-add one patch for cancelling the last frame handling flow
-add one patch for deletting zeroing the reserved fields
-move changing data type of max/min width/height to patch 10/18
-add one patch for renaming existing functions/defines/variables

Change compared to v8:
-change commit message of patch 02/18
-use pm_runtime_put() to replace pm_runtime_put_sync() of patch 05/18
-add one patch for deletting the resetting hardware flow in the system PM ops
-use v4l2_m2m_suspend() and v4l2_m2m_resume() to improve the implemention
of the system PM ops. This patch(07/18) depends on [RFC,V4,1/4] media:
v4l2_mem2mem: add v4l2_m2m_suspend, v4l2_m2m_resume(https://patchwork.kernel.org/patch/11272917/)
-add one patch for cancelling the last frame handling flow
-add one patch for deletting zeroing the reserved fields
-move changing data type of max/min width/height to patch 10/18
-add one patch for renaming existing functions/defines/variables

Delete platform_get_resource operation for irq.
Return actual value rather than EINVAL when fail to get and request
irq.

The driver can be instantiated multiple times, e.g. for a decoder and
an encoder. Moreover, other drivers could coexist on the same system.
This makes the static video node number assignment pointless, so switch
to automatic assignment instead.

Call pm_runtime_get_sync() before starting a frame and then
pm_runtime_put() after completing it. This can save power for the time
between processing two frames.

Add v4l2_m2m_suspend() function call in mtk_jpeg_suspend() to make sure
that the current frame is processed completely before suspend.
Add v4l2_m2m_resume() function call in mtk_jpeg_resume() to unblock the
driver from scheduling next frame.

There is no need to queue an empty buffer for signaling a last frame,
because all frames are separate from each other in JPEG.

Add mtk jpeg encode v4l2 driver based on jpeg decode, because that jpeg
decode and encode have great similarities with function operation.
Signed-off-by: Xia Jiang <xia.jiang@mediatek.com>
---
v9: add member variable(struct v4l2_rect) in out_q structure for storing
the active crop information.
move the renaming exsting functions/defines/variables to a separate patch.

Add mtk jpeg encode v4l2 driver based on jpeg decode, because that jpeg
decode and encode have great similarities with function operation.
Signed-off-by: Xia Jiang <xia.jiang@mediatek.com>
---
v9: add member variable(struct v4l2_rect) in out_q structure for storing
the active crop information.
move the renaming exsting functions/defines/variables to a separate patch.

Add mtk jpeg encode v4l2 driver based on jpeg decode, because that jpeg
decode and encode have great similarities with function operation.
Signed-off-by: Xia Jiang <xia.jiang@mediatek.com>
---
v9: add member variable(struct v4l2_rect) in out_q structure for storing
the active crop information.
move the renaming exsting functions/defines/variables to a separate patch.
