Mauro Carvalho Chehab fa132a64e2 [media] bt8xx: use pr_foo() macros instead of printk()
Replace printk() macros by their pr_foo() counterparts, using
pr_cont() for continuation lines.

Mauro Carvalho Chehab 7c64691353 [media] bt8xx/dst: use a more standard way to print messages
This driver uses a weird, non-standard macro to print errors.
It allows hiding all messages, including error ones, with doesn't
seem a good idea.

Instead, replace it to pr_foo(), and, for error messages,
use pr_err().

The remaining messages were previouly classified as notice,
info or debug, but they all looked like debug messages.

So, add a dprintk() macro using the "verbose" modprobe
argument to select what will be displayed.

Mauro Carvalho Chehab fed9d8f3cd [media] stv090x: get rid of continuation lines
This driver has printk continuation lines for debugging purposes.

this won't work as expected anymore.

So, use %*ph and get rid of it.

Marek Szyprowski c0026c7bfb [media] s5p-mfc: Fix clock management in s5p_mfc_release() function
Clock control indirectly requires access to MFC device, so call it only
if we are sure that the device exists in s5p_mfc_release function.
s5p_mfc_remove() calls s5p_mfc_final_pm(), which releases all PM related
resources, including clocks, so any call to clocks related functions
is not valid after s5p_mfc_final_pm().

Marek Szyprowski c5086f130a [media] s5p-mfc: Use clock gating only on MFC v5 hardware
Newer MFC hardware have internal clock gating feature, so additional
software-triggered clock gating sometimes causes misbehavior of the MFC
firmware and results in freeze or crash. This patch changes the driver
to use software-triggered clock gating only when working with v5 MFC
hardware, where it has been proven to work properly.

Ulf Hansson 81aa8d141f [media] exynos-gsc: Make PM callbacks available conditionally
There are no need to set up the PM callbacks (runtime and system) unless
they are being used. It also causes compiler warnings about unused
functions.

Silence the warnings by making them available for CONFIG_PM (runtime
callbacks) and CONFIG_PM_SLEEP (system sleep callbacks).

Media drivers that use the videobuf2 framework have to give back to vb2
all the buffers that received from vb2 using its .buf_queue callback.

But the exynos-gsc driver isn't doing a proper cleanup so vb2 complains
that the number of buffers enqueued and received are not balanced:

Javier Martinez Canillas f4ca5030b3 [media] exynos-gsc: don't release a non-dynamically allocated video_device
The struct v4l2_device instance for the G-Scaler is not dyanmically
allocated but a member of the struct gsc_dev. In fact, the assigned
.release callback is video_device_release_empty().

But gsc_register_m2m_device() attempts to release the v4l2_device by
calling video_device_release() in its error path. This is wrong since
the v4l2_device wasn't allocated directly and will be freed once its
parent struct gsc_dev is freed.

While being there, rename the remaining goto label in the error path
to something that better explains the error path cleanup.

Javier Martinez Canillas 652bb68018 [media] exynos-gsc: do proper bytesperline and sizeimage calculation
The driver don't take into account the differences between packed, semi
planar and multi planar formats when calculating the pixel format bytes
per lines and image size values. This makes GStreamer to fail when the
following formats are used NV12, NV21, NV16, NV61, YV12, I420 and Y42B:

"gst_video_frame_map_id: failed to map video frame plane 1"

Nicolas suggested to use the logic found in the Exynos FIMC v4l2 driver
since does this correctly. So this patch changes the bytes per line and
image size calculation according to what's done in this media driver.

After this patch most supported formats work correctly. There are still
issues with the NV21 and NV61 formats, but that seems to be a separate
problem since NV12 and NV16 work and these formats use the same values.

So this can be fixed as a follow-up and shouldn't be a blocker for this
change that improves the driver's support.

Javier Martinez Canillas 8a661745b7 [media] exynos-gsc: fix supported RGB pixel format
The driver exposes 32-bit A/XRGB 8-8-8-8 as supported format but testing
shows that using this format produces frames with wrong colors. The test
was done with the following GStreamer pipeline:

$ gst-launch-1.0 videotestsrc num-buffers=20 ! video/x-raw,format=UYVY \
! v4l2video3convert ! video/x-raw,format=xRGB ! videoconvert ! kmssink

The manual seems to state that the Pixel Format are in Little Endianness
so instead use the 32-bit BGRA/X 8-8-8-8 pixel format. This format works
correctly when using the following pipeline:

$ gst-launch-1.0 videotestsrc num-buffers=20 ! video/x-raw,format=UYVY \
! v4l2video3convert ! video/x-raw,format=BGRx ! kmssink

This change is similar to commit 7f2816e51e ("[media] s5p-fimc: Changed
RGB32 to BGR32") that fixed the same issue on a different Samsung driver.

Javier Martinez Canillas daba4dfbd2 [media] exynos-gsc: don't clear format when freeing buffers with REQBUFS(0)
User-space applications can use the VIDIOC_REQBUFS ioctl to determine if a
memory mapped, user pointer or DMABUF based I/O is supported by a driver.

For example, GStreamer attempts to determine the I/O methods supported by
the driver by doing many VIDIOC_REQBUFS ioctl calls with different memory
types and count 0. And then the real VIDIOC_REQBUFS call with count == n
is be made to allocate the buffers. But for count 0, the driver not only
frees the buffers but also clears the format set before with VIDIOC_S_FMT.

This is a problem since STREAMON fails if a format isn't set but GStreamer
first sets a format and then tries to determine the supported I/O methods,
so the format will be cleared on REQBUFS(0), before the call to STREAMON.

To avoid this issue, only free the buffers on VIDIOC_REQBUFS(0) but don't
clear the format. Since is completely valid to set the format and then do
different calls to REQBUFS before a call to STREAMON.
