V4L/DVB (12288): dvb-pll: Add support for Samsung TBDU18132 DVB-S NIM
Tuner parameters taken from flexcop driver. This PLL has a 17 bit divisor
while the dvb-pll driver is designed for 15 bit divisors. It's not a
problem as 15 bits is enough for the tuner's entire range. But if a larger
range was wanted, it could be done by adding additional bands with the
extra divisor bits appearing as band switch bits.
