654a731be1 [media] media: s5p-mfc: use vb2_ops_wait_prepare/finish helper
This patch drops driver specific wait_prepare() and
wait_finish() callbacks from vb2_ops and instead uses
the the helpers vb2_ops_wait_prepare/finish() provided
by the vb2 core, the lock member of the queue needs
to be initalized to a mutex so that vb2 helpers
vb2_ops_wait_prepare/finish() can make use of it.

e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

 - A new driver for some PCIe DVBSky cards
 - A new remote controller driver: meson-ir
 - One LIRC staging driver got rewritten and promoted to mainstream:
   igorplugusb
 - A new tuner driver (m88rs6000t)
 - The old omap2 media driver got removed from staging.  This driver
   uses an old DMA API and it is likely broken on recent kernels.
   Nobody cared enough to fix it
 - Media bus format moved to a separate header, as DRM will also use the
   definitions there
 - mem2mem_testdev were renamed to vim2m, in order to use the same
   naming convention taken by the other virtual test driver (vivid)
 - Added a new driver for coda SoC (coda-jpeg)
 - The cx88 driver got converted to use videobuf2 core
 - Make DMABUF export buffer to work with DMA Scatter/Gather and Vmalloc
   cores
 - Lots of other fixes, improvements and cleanups on the drivers.

e243c7c1a4 media / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM
After commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.

The alternative of CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME may be
replaced with CONFIG_PM too.

Make these changes everywhere under drivers/media/.

9a7bc6b0c4 [media] s5p-mfc: Don't crash the kernel if the watchdog kicks in
If the software watchdog kicks in, the watchdog worker is not synchronized
with hardware interrupts and does not block other instances. It's possible
for it to clear the hw_lock, making other instances trigger a BUG() on
hw_lock checks. Since it's not fatal to clear the hw_lock to zero twice,
just WARN in those cases for now. We should not explode, as firmware will
return errors as needed for other instances after it's reloaded, or they
will time out.

A clean fix should involve killing other instances when watchdog kicks in,
but requires a major redesign of locking in the driver.

bb21c54af7 [media] s5p-mfc: Only set timestamp/timecode for new frames
Timestamp i of a previously decoded buffer was overwritten for some
H.264 streams with timestamp i+1 of the next buffer. This happened when
encountering frame_type S5P_FIMV_DECODE_FRAME_SKIPPED, indicating no
new frame.

In most cases this wrong indexing might not have been noticed except
for a one frame delay in frame presentation. For H.264 streams though
that require reordering of frames for presentation, it caused a slightly
erratic presentation time lookup and consequently dropped frames in the
Pepper Flash plugin.

643709941d [media] s5p-mfc: clear 'enter_suspend' flag if suspend fails
The enter_suspend flag is set after we enter mfc suspend function but if
suspend fails after that due to any reason (like hardware timeout etc),
this flag must be cleared before returning an error. Otherwise, this
flag never gets cleared and the MFC suspend will always return an error
on subsequent tries. If clock off fails, disable hw_lock also.

7c672812fe [media] s5p-mfc: Use decode status instead of display status on MFCv5
Commit 90c0ae5009 changed how the frame_type of a decoded frame
gets determined, by switching from the get_dec_frame_type to
get_disp_frame_type operation. Unfortunately it seems that on MFC v5 the
result of get_disp_frame_type is always 0 (no display) when decoding
(tested with H264), resulting in no frame ever being output from the
decoder.

This patch reverts MFC v5 to the previous behaviour while keeping the
new behaviour for v6 and up.

e2c3be2aff [media] s5p-mfc: Fix sparse errors in the MFC driver
The following error: "error: incompatible types in conditional expression
(different base types)" was reported multiple times for the s5p-mfc
driver. This error was caused by two macro definitions - s5p_mfc_hw_call
(in s5p_mfc_common.h) and WRITEL (in s5p_mfc_opr_v6.c).

In the former case the macro assumed that all ops return a value, but some
ops return void. The solution to this problem was the addition of a
s5p_mfc_hw_call_void macro.

In the latter case the macro used the ?: construction to check whether
the address is non zero. This is not necessary after the driver left the
development and debugging cycle, so the READL and WRITEL macros were
removed.

6a9c6f6812 [media] s5p-mfc: Add variants to access mfc registers
This patch is needed in preparation to add MFC V8
where the register offsets are changed w.r.t MFC V6/V7.

This patch adds variants of MFC V6 and V7 while
accessing MFC registers. Registers are kept in mfc context
and are initialized to a particular MFC variant during probe,
which is used instead of macros.

This avoids duplication of the code for MFC variants
V6 & V7, and reduces the if_else checks while accessing
registers of different MFC variants.

f49f3ed519 [media] s5p-mfc: Don't try to resubmit VP8 bitstream buffer for decode
Currently, for formats that are not H264, MFC driver will check
the consumed stream size returned by the firmware and, based on that,
will try to decide whether the bitstream buffer contained more than
one frame. If the size of the buffer is larger than the consumed
stream, it assumes that there are more frames in the buffer and that the
buffer should be resubmitted for decode. This rarely works though and
actually introduces problems, because:

- v7 firmware will always return consumed stream size equal to whatever
the driver passed to it when running decode (which is the size of the whole
buffer), which means we will never try to resubmit, because the firmware
will always tell us that it consumed all the data we passed to it;

- v6 firmware will return the number of consumed bytes, but will not
include the padding ("stuffing") bytes that are allowed after the frame
in VP8. Since there is no way of figuring out how many of those bytes
follow the frame without getting the frame size from IVF headers (or
somewhere else, but not from the stream itself), the driver tries to guess that
padding size is not larger than 4 bytes, which is not always true;

The only way to make it work is to queue only one frame per buffer from
userspace and the check in the kernel is useless and wrong for VP8.
So adding VP8 also along with H264 to disallow re-submitting of buffer
back to hardware for decode.

9d87e8375d [media] s5p-mfc: Don't allocate codec buffers on STREAMON
Currently, we allocate private codec buffers on STREAMON, which may fail
if we are out of memory. We don't check for failure though, which will
make us crash with the codec accessing random memory.

We shouldn't be failing STREAMON with out of memory errors though. So move
the allocation of private codec buffers to REQBUFS for OUTPUT queue. Also,
move MFC instance opening and closing to REQBUFS as well, as it's tied to
allocation and deallocation of private codec buffers.

a0517f5d4d [media] s5p-mfc: Copy timestamps only when a frame is produced
Timestamps for destination buffers are assigned by copying them from
corresponding source buffers when the decode operation results in a frame
being outputted to a destination buffer. But the decision when to do this, i.e.
whether the decode operation on current source buffer produced a destination
frame, is wrongly based on "display status". Display status reflects the status
of the destination buffer, not source.

This used to work for firmwares version <= 6, because in addition to the above,
we'd check the decoded frame type register, which was set to "skipped" if
a destination frame was not produced, exiting early from
s5p_mfc_handle_frame_new().
Firmware >=7 does not set the frame type register for frames that were not
decoded anymore though, which results in us wrongly overwriting timestamps of
previously decoded buffers (firmware reports the same destination buffer address
as previously decoded one if a frame wasn't decoded during current operation).

To do it properly, we should be basing our decision to copy the timestamp on the
status of the source buffer, i.e. "decode status". The decode status register
values are confusing, because in its case "display" means "a frame has been
outputted to a destination buffer". We should copy if "decode and display"
is returned in it. This also works on <= v6 firmware, which behaves in the same
way with regards to decode status register.

76a4ddbd52 [media] s5p-mfc: call wake_up_dev if in suspend mode
If a frame is still decoding when system enters suspend mode, we wait
on the device queue for a interrupt condition. This sometimes leads to a
timeout because the device queue might not be woken up everytime.
Usually, the context queue gets woken up when that context's frame gets
decoded. This patch adds a condition to wake up the device queue along
with the context queue when the system is in suspend mode.
Since the device queue is now woken up, we don't have to check the
context's int_cond flag while waiting. Also, we can skip calling try_run
after waking up the device queue to ensure that we don't have to wait
for more than one frame to be processed.
