Sjoerd Simons 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.

Kamil Debski 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.

Kiran AVND 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.

Pawel Osciak 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.

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.

Pawel Osciak 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.

Prathyush K 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.

this special clock without a clk_enable call. As this
sclk is the parent of gate clock, it gets prepared and
enabled along with the gate clock. So there is no need
for the driver to use this sclk. This patch removes the
sclk usage from driver.

Arun Kumar K e9d98ddc0a [media] s5p-mfc: Update v6 encoder buffer alloc
MFC v6 needs minimum number of output buffers to be queued
for encoder depending on the stream type and profile.
The patch modifies the driver so that encoding cannot be
started with lesser number of OUTPUT buffers than required.
This also fixes the crash happeninig during multi instance
encoder-decoder simultaneous run due to memory allocation
happening from interrupt context.

This change removes the use of __devinit, __devexit_p, __devinitdata,

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
