2008-12-29V4L/DVB (9633): Put s5h1411 into low power mode at end of attach() callDevin Heitmueller
Place the s5h1411 into low power mode until first use (to handle the case where the user plugs in the device and then doesn't use it for a while). On the Pinnacle 801e, this brings the power usage from 126ma down to 82ma. Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Power down the s5h1411 demodulator when not in use (on the Pinnacle 801e, this brings idle power from 123ma down to 84ma). Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Acked-by: Steven Toth <stoth@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-10-21V4L/DVB (9315): s5h1411: Skip reconfiguring demod modulation if already at ↵Devin Heitmueller
the desired modulation If we are already at the desired modulation, there is no need to reconfigure the demod (at a tuning time cost) Note that this change revealed that although the datasheet says the demod starts out in VSB-8 mode, the first tuning was failing consistently unless we went through the work of setting the registers. So add a field to denote this case so we always do the enable_frontend call, even if the first tuning request is for VSB-8.

2008-10-21V4L/DVB (9314): s5h1411: Perform s5h1411 soft reset after tuningDevin Heitmueller
If you instruct the tuner to change frequencies, it can take up to 2500ms to get a demod lock. By performing a soft reset after the tuning call (which is consistent with how the Pinnacle 801e Windows driver behaves), you get a demod lock inside of 300ms Signed-off-by: Devin Heitmueller <devin.heitmueller@gmail.com> Reviewed-by: Michael Krufky <mkrufky@linuxtv.org> Acked-by: Steven Toth <stoth@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
