No datasheet, data take from code in flexcop driver. That code rounded
down the divisor rather than rounding to nearest, which was probably not
intentional and the dvb-pll code will round to nearest.

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.

This feature, along with support for the tuners that used it,

Add a module option to force the dvb-pll module to use an alternate dvb-pll
description without having to recompile the kernel.
Having a module option like this is useful in some cases, where the vendor
may release an alternate revision of the hardware using a different tuner,
but without changing the pci subsystem / usb device ids.
This option is intended for debugging purposes _only_.

The last user of dvb_pll_configure was the dvb-usb function
dvb_usb_tuner_calc_regs(), which was nothing more than a wrapper around
dvb_pll_configure(). It's just a copy of the functionality provided by
the tuner_ops calc_regs method, and can be deleted.
There were two users of dvb_usb_tuner_calc_regs().
One was dvb_usb_tuner_set_params_i2c(), which is converted to use
fe->ops.tuner_ops.calc_regs().
The other was the digitv driver. This driver can use one of two demods,
mt352 or nxt6000. For the mt352, the driver would set
tuner_ops.calc_regs to dvb_usb_tuner_calc_regs(). We can just attach
dvb_pll and use the tuner_ops.calc_regs() provided by that module.
For the nxt600, the driver would set tuner_ops.set_params to
digitv_nxt6000_tuner_set_params. That function would in turn use
dvb_usb_tuner_calc_regs(). We convert it to use tuner_ops.calc_regs()
instead, and use dvb_pll_attach.
The digitv_tuner_attach() needs to know which frontend was attached by
digitv_frontend_attach(), since the nxt6000 needs tuner_ops.set_params()
to be overridden with digitv_nxt6000_tuner_set_params(). So to do this a
digitv_state that says which frontend was used is added to the
dvb_usb_device private state field.

Enhance the dvb-pll definition of the fmd1216 tuner by adding an init sequence
and a sleep sequence.
The init sequence sets the AGC control register to 0xa0, selecting the fast
time constant and 112 dBuV take-over point. This the recommended value for
DVB-T operation.
The sleep sequence sets bit P4 (which is believed to turn the analog
demodulator on), turns off the tuning voltage, and sets the AGC control
register to 0x60 (external AGC voltage, the recommended value for analog
operation).
The existing dvb-pll users in the cx88 driver, listed below, will gain these
init and sleep sequences.
CX88_BOARD_HAUPPAUGE_HVR1100 Hauppauge WinTV-HVR1100 DVB-T/Hybrid

CX88_BOARD_HAUPPAUGE_HVR1300 Hauppauge WinTV-HVR1300 DVB-T/Hybrid MPEG Encod
This non-dvb-pll user in the cx88 driver should only gain the sleep sequence,
as it already had an equivalent init sequence. The non-dvb-pll code for this
user is removed.
X88_BOARD_DNTV_LIVE_DVB_T_PRO digitalnow DNTV Live! DVB-T Pro
In these saa7134 driver, these non-dvb-pll users are converted to use dvb-pll:
SAA7134_BOARD_MD7134 Medion 7134
SAA7134_BOARD_ASUS_EUROPA2_HYBRID Asus Europa2 OEM
The saa7134 functions philips_fmd1216_tuner_init(),
philips_fmd1216_tuner_sleep(), and philips_fmd1216_tuner_set_params() are
deleted and the dvb-pll versions are used.
This should result in equivalent sleep, init, and tuning sequences being sent
to the tuner.
For the cxusb driver, only one board is effected:
USB_PID_MEDION_MD95700 Medion MD95700
This board used dvb_usb_tuner_init_i2c() and dvb_usb_tuner_set_params_i2c()
for init and tuning, respectively. These functions are effectively the same
as the dvb-pll versions. They call a tuner pass control function defined at
the dvb-usb level, but this does not matter, as this card does not have a
tuner pass control function (only the dib3000mb does). This board will gain
the sleep sequence, while init and tuning should be unchanged.

The dvb-pll sleep function could only send a 2-byte sequence to the PLL.
This isn't enough in some cases, for example fmd1216me will need to send
a 4-byte command to set both BB and AB to the correct values.
Instead of using a fake band with a frequency of 0 to store the sleep
data (which has room for only two bytes), the new sleep function works
like the init function. A new pointer is added to the pll description,
and when non-NULL points to a buffer with the length and data to send.

Some PLLs had one half the step size added to the offset, so that the
divisor would be rounded to the nearest integer. Some didn't and so
would always be rounded down.
This makes dvb-pll round to the nearest when calculating the divisor,
without the offset needing to be fudged. PLLs that had a fudged offset
have the offset changed to be just the IF frequency.
The satellite PLL dvb_pll_philips_sd1878_tda8261 was rounding up for some
reason, and I've kept it that way.
In addition, frequencies that were rounded to the nearest kHz are
extended to full Hz resolution. One sixth MHz step sizes that were
listed as 166,666 Hz are changed to 166,667 Hz, which is slightly closer.
PLLs that were already rounding:
dvb_pll_tda665x, offset was 36 1/6 (to nearest kHz) + step/2
dvb_pll_fmd1216me, offset was 36 1/8 (to two digits) + step/2
dvb_pll_thomson_fe6600, offset was 36 1/8 (to two digits) + step/2
dvb_pll_env57h1xd5, offset was 36 1/8 + step
Note that the last PLL, dvb_pll_env57h1xd5, appears to have had a bug in
the offset. Rather than adding stepsize/2, it was adding a full
stepsize. The PLL definition originally came from the dibusb driver,
which used 36 1/8 + step/2. The change to 36 1/8 + step was probably a
mistake added when the tuner was converted to dvb-pll.

The code of the dvb-pll driver and the lgh06xf driver is nearly
identical. The main difference is that the lgh06xf driver would set the
AGC TOP value on every tune call. The dvb-pll driver now has the ability
to set the AGC TOP when the front-end device is opened, which is a better
way to go about it. By using this ability of dvb-pll, the lgh06xf driver
is made unnecessary.
There is one other difference. dvb-pll will probe for the presence of an
I2C pll chip by doing a one byte read, the lgh06xf driver did not do
this. In some devices the PLL is not reachable over I2C at the timer the
tuner is attached. Some more initialization, such as firmware loading,
must take place first. None of the devices using a LG-H06xF should have
this problem.

Some tuners need or benefit from initialization, to change certain
settings from their power on default values.
Typically, tuners with TUA603x PLLs can benefit from setting the AGC TOP
value to something else. This patch includes code to set the AGC TOP to
103 dBuV for the Thomson DTT-761x tuners, which I have experimentally
verified gives the best SNR readings, increasing SNR by about 0.19 dB
over the default value.
Other tuners can make use of this as well. For example, the separate LG
TDVS-H06xF driver's only difference from dvb-pll is this same setting of
AGC TOP value.

This patch removes some duplicated code by returning the frequency set by

and dvb_pll_calc_regs().
If the return value of dvb_pll_configure is less than zero, it is an error
code. Otherwise, the return value is the frequency actually set by the
function.

From: Chris Pascoe <c.pascoe@itee.uq.edu.au>
Typical wiring of MT352 and ZL10353 based tuners differs from dvb-pll's
expectation that the PLL is directly accessible. On these boards, the
PLL is actually hidden behind the demodulator, and as such can only be
accessed via the demodulator's interface. It was failing to communicate
with the PLL during an attach test and subsequently not connecting the
tuner ops.
By passing a NULL I2C bus handle to dvb_pll_attach, this accessibility
check can be bypassed. Do this for the affected boards. Also fix a
possible NULL dereference at sleep time, which would otherwise be
exposed by this change.
