If 'media_entity_pads_init()' fails, we must free the resources allocated
by 'v4l2_ctrl_handler_init()', as already done in the previous error
handling path.
'goto' the right label to fix it.

Dear reviewers,
As the dt-binding patch has been accepted, would any help set the driver patch
be accepted too? Any missing action from my side blocked the process. Thanks in

checking, which are caused by calling standard ioctls using a function

Hi,
This series introduces the Media driver to work with the i.MX7 SoC. it uses the
already existing imx media core drivers but since the i.MX7, contrary to
i.MX5/6, do not have an IPU and because of that some changes in the imx media
core are made along this series to make it support that case.

Since the GPIO 3 controls both reset and powerdown, we rename it to reset. Fix
the polarity of this, as it is a low active signal and not an high active.
As at it, rename the mipi endpoint in the example to be coherent with the a real

Use the newly-introduced SRAM controller compatible for the A20 instead
of its A10 fashion.

This presents a third iteration of the updated Sunxi-Cedrus driver,
that supports the Video Engine found in most Allwinner SoCs, starting
with the A10. It was tested on the A13, A20 and A33.

submitted by Florent Revest using a previo

This introduces support for the SRAM C1 section, that is controlled by
the system controller. This SRAM area can be muxed either to the CPU
or the Video Engine, that needs this area to store various tables (e.g.
the Huffman VLD decoding tables).

This introduces the Sunxi-Cedrus VPU driver that supports the VPU found
in Allwinner SoCs, also known as Video Engine. It is implemented through
a v4l2 m2m decoder device and a media device (used for media requests).
So far, it only supports MPEG2 decoding.

This introduces platform-specific compatibles for the A13, A20 and A33

this point, although this might become the case in the future.

The isp stat driver allocates memory for DMA and uses GFP_DMA flag for
dev_alloc_coherent. The flag is no longer needed as the DMA mask is used
for the purpose. Remove it.

Hi,
These patches fix a useless check in ispstat as well as get rid of the
GFP_DMA.
