[media] au8522: Handle differences in comb filter config for s-video input

2010-12-29T10:16:34+00:00

Tweak the comb filter config when in s-video mode to match the Hauppauge
Windows driver values (based on register dumps).

[media] au8522: fix clamp control for different video modes

2010-12-29T10:16:34+00:00

Straighten out the clamp control configurations for the various video modes,
based off of register diffs done against the Hauppauge Windows driver.

[media] au8522: cleanup code which disables audio decoder

2010-12-29T10:16:33+00:00

Cleanup the routine which disables the audio decoder.  In particular, the i2s
output was being shut off but the audio processor itself was not, resulting
in more power being consumed than needed.

[media] au8522: Properly set default brightness

2010-12-29T10:16:33+00:00

The chip's default value for the brightness didn't match what we were sending
back in the queryctrl ioctl(), so if the application actually set the
brightness to the "default", it would actually end up being way too bright.

V4L/DVB: au8522_decoder: g/s_fmt doesn't do anything: remove

2010-06-01T04:21:37+00:00

g/s_fmt is going to disappear, so if it is not doing anything, then
just remove it.

V4L/DVB: au8522: fix case where we don't perform the first tune after going digital

2010-05-18T03:46:22+00:00

Address a problem found in MythTV where if we are in digital mode, switch to
analog mode, and the switch back to digital mode, the first tuning request
after switching back to digital mode gets dropped.  This is because the au8522
maintains internal state, and would think the demod was already tuned to the
target frequency.

Thanks to Zaphod Beeblebrox for reporting this issue.

V4L/DVB: au8522: fix race condition in switching from digital to analog mode

2010-05-18T03:46:21+00:00

With applications like MythTV, switching inputs results in closing the digital
side and then immediately opening the analog side.  This exposes a race
condition where the dvb_frontend kernel thread powers down the chip and closes
the i2c gate even though we're in the middle of bringing up the analog part
of the chip (since the shutdown of the dvb_frontend kernel thread occurs
asychronously).

Introduce a construct to keep track of what mode we're in, and drop requests
to power down or management the gate if we've already switched to analog mode.

Thanks to Zaphod Beeblebrox for reporting this issue.

V4L/DVB (13688): au8522: modify the attributes of local filter coefficients

2009-12-16T11:27:58+00:00

Make the local filter coefficients static and const. This will eliminate the
following sparse warnings (see "make C=1"):
 * au8522_decoder.c:71:31: warning: symbol 'filter_coef' was not declared. Should it be static?
 * au8522_decoder.c:113:31: warning: symbol 'lpfilter_coef' was not declared. Should it be static?
