      [media] dvb: Get rid of typedev usage for enums · 0df289a2
      由 Mauro Carvalho Chehab 提交于 
      The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.

      [media] cx23885: fix size helper functions · 1c5eaa23
      由 Hans Verkuil 提交于 
      The norm_swidth function was unused and is dropped. It's not clear
what the purpose of that function was.

The norm_maxh function was changed so it tests for 60 Hz standards
rather than for 50 Hz standards. The is the preferred order.

The norm_maxw function was poorly written and used: it gives the maximum
allowed line width for the given standard. For 60 Hz that's 720, but
for 50 Hz that's 768 which allows for 768x576 which gives you square
pixels. For 60 Hz formats it is 640x480 that gives square pixels, so
there is no need to go beyond 720.

The initial width was set using norm_maxh(), which was wrong. Just set
to 720, that's what you normally use. Since the initial standard was
NTSC anyway the initial width was always 720 anyway.

      [media] cx23885: remove btcx-risc dependency · 4d63a25c
      由 Hans Verkuil 提交于 
      It's just as easy to do it in the driver. This dependency only uses a
fraction of the btcx-risc module and doing it directly in the driver
adds only a few lines. The btcx-risc module is really meant for the
bttv driver, not for other drivers.

      [media] cx23885: convert to vb2 · 453afdd9
      由 Hans Verkuil 提交于 
      As usual, this patch is very large due to the fact that half a vb2 conversion
isn't possible. And since this affects 417, alsa, core, dvb, vbi and video the
changes are all over.

What made this more difficult was the peculiar way the risc program was setup.
The driver allowed for running out of buffers in which case the DMA would stop
and restart when the next buffer was queued. There was also a complicated
timeout system for when buffers weren't filled. This was replaced by a much
simpler scheme where there is always one buffer around and the DMA will just
cycle that buffer until a new buffer is queued. In that case the previous
buffer will be chained to the new buffer. An interrupt is generated at the
start of the new buffer telling the driver that the previous buffer can be
passed on to userspace.

Much simpler and more robust. The old code seems to be copied from the
cx88 driver. But it didn't fit the vb2 ops very well and replacing it with
the new scheme made the code easier to understand. Not to mention that this
patch removes 600 lines of code.
