V4L/DVB (4609): Improved i2c performance on software bitbang algoritm
Software I2C were using a very conservative value of udelay=16, meaning about
20Kbps. According with Philips I2C datasheet, the i2c should answer well for
times at the order of 4.7 us. So, using udelay=5 should work for all devices.
After this patch, the speed should be close to 66,67 Kbps, with the current
kernel software bitbang, with 30/60 duty cycle.
Anyway, added a new parameter (i2c_udelay) that would allow using conservative
values, if eventually a hardware doesn't support the datasheet values.
Thanks to Jean Delvare <khali@linux-fr.org> for pointing this improvement.
This driver was originally in budget-av.c, however I have extracted it into
a seperate file to permit reuse.
I also reworked the code to make it maintainable. I then examined the KNC1
windows drivers and rewrote the code in order to configure the PLL as they
do. This solves a lot of reported tuning problems.

V4L/DVB (4548): Better temporal filter handling.
Adjust temporal filter if necessary. The problem with the temporal
filter is that it works well with full resolution capturing, but
not when the capture window is scaled (the filter introduces
a ghosting effect). So if the capture window changed, and there is
no updated filter value, then the filter is set depending on whether
the new window is full resolution or not.
For full resolution a setting of 8 really improves the video
quality, especially if the original video quality is suboptimal.

Typical wiring of MT352 and ZL10353 based tuners differs from dvb-pll's

PLL is actually hidden behind the demodulator, and as such can only be
accessed via the demodulator's interface. It was failing to communicate
