The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

The newly added mtk-vcodec driver produces a number of warnings in an
ARM allmodconfig build, mainly since it assumes that dma_addr_t is
32-bit wide:
mtk-vcodec/venc/venc_vp8_if.c: In function 'vp8_enc_alloc_work_buf':
mtk-vcodec/venc/venc_vp8_if.c:212:191: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
mtk-vcodec/venc/venc_h264_if.c: In function 'h264_enc_alloc_work_buf':
mtk-vcodec/venc/venc_h264_if.c:297:190: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
This rearranges the format strings and type casts to what they should
have been in order to avoid the warnings. e0f80d8d62f5 ("[media]
mtk-vcodec: fix two compiler warnings") fixed some of the problems that
were introduced at the same time, but missed two others.

The newly added FCP support in the vsp1 driver causes a link error
when CONFIG_RENESAS_FCP=m, since it's not reachable by built-in code:
drivers/media/built-in.o: In function `vsp1_remove':
:(.text+0xdeca0): undefined reference to `rcar_fcp_put'
drivers/media/built-in.o: In function `vsp1_probe':
:(.text+0xdef44): undefined reference to `rcar_fcp_get'
We already have a conditional dependency on FCP that requires
it for ARM64, so for all others we just have to prevent setting
RENESAS_VSP1=y when RENESAS_FCP=m by extending the FCP dependency.

Building without CONFIG_PM results in a harmless warning from
slightly incorrect #ifdef guards:
drivers/media/platform/vsp1/vsp1_drv.c:525:12: error: 'vsp1_pm_runtime_resume' defined but not used [-Werror=unused-function]
drivers/media/platform/vsp1/vsp1_drv.c:516:12: error: 'vsp1_pm_runtime_suspend' defined but not used [-Werror=unused-function]
This removes the existing #ifdef and instead marks all four
PM functions as __maybe_unused.

Make this a proper typed array. Drop the old allocate context code since
that is no longer used.
Note that the memops functions now get a struct device pointer instead of

a struct containing only a struct device pointer).
This code is now a lot cleaner.

This fixes dropping ownership of buffers in the driver's stop_streaming
callback, so buffers on the memory-to-memory video nodes are properly
released, also in case when the driver has a buffer only on one of the
queues (OUTPUT, CAPTURE) before the video node close.
The issue was being reported by videobuf2 with a following warning while
checking q->owned_by_drv_count:

According to the V4L2 documentation the driver and card fields should be
used to identify the driver and the device but the s5p-mfc driver fills
those field using the platform device name, which in turn is the name of
the device DT node.
So not only the filled information isn't correct but also the same values
are used in all the fields for both the encoder and decoder video devices.
Before this patch:
Driver Info (not using libv4l2):
Driver name : 11000000.codec
Card type : 11000000.codec
Bus info : platform:11000000.codec
Driver version: 4.7.0
Driver Info (not using libv4l2):
Driver name : 11000000.codec
Card type : 11000000.codec
Bus info : platform:11000000.codec
Driver version: 4.7.0
After this patch:
Driver Info (not using libv4l2):
Driver name : s5p-mfc
Card type : s5p-mfc-dec
Bus info : platform:11000000.codec
Driver version: 4.7.0
Driver Info (not using libv4l2):
Driver name : s5p-mfc
Card type : s5p-mfc-enc

The driver doesn't set the struct v4l2_capability bus_info field so the
v4l2-compliance tool reports the following errors for VIDIOC_QUERYCAP:
Required ioctls:
VIDIOC_QUERYCAP returned 0 (Success)
fail: v4l2-compliance.cpp(304): string empty
fail: v4l2-compliance.cpp(528): check_ustring(vcap.bus_info, sizeof(vcap.bus_info))
test VIDIOC_QUERYCAP: FAIL
This patch fixes by setting the field in VIDIOC_QUERYCAP ioctl handler:
Required ioctls:
VIDIOC_QUERYCAP returned 0 (Success)
test VIDIOC_QUERYCAP: OK

The streaming field in struct vb2_queue is meant to be private and should
not be used by drivers directly, instead the vb2_is_streaming() function
should be used to check the videobuf2 queue streaming status.

The V4L2 documentation says that applications must call the VIDIOC_REQBUFS
ioctl to determine if a memory mapped, user pointer or DMABUF based I/O is
supported by the driver.
For example GStreamer does this by first calling VIDIOC_REQBUFS with count
zero for all the possible streaming I/O methods and then finally doing the
real VIDIOC_REQBUFS with count N using a known to be supported memory type.
But the driver prints an error on VIDIOC_REQBUFS if the memory type is not
supported which leads to the following errors that can confuse the users:
[ 178.704390] vidioc_reqbufs:575: Only V4L2_MEMORY_MMAP is supported
[ 178.704666] vidioc_reqbufs:575: Only V4L2_MEMORY_MMAP is supported

Fix null pointer deference in clk_core_enable() when driver unbind is run
when there is an application has an active pipeline playing.
s5p_mfc_release() gets called after s5p_mfc_final_pm() disables and does
clk_put() and s5p_mfc_release() attempts to enable clock and runs into
null pointer deference accessing invalid pointer.
