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. Signed-off-by:

The IF frequency was specified for each band, but it's not something that changes from band to band. None of the tuner definitions had a different IF frequency (called offset) from one band to another. Acked-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

This patch removes some duplicated code by returning the frequency set by dvb_pll_configure(), instead of recalculating it again in dvb_pll_set_params() 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. Signed-off-by:

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. Signed-off-by:

Trent Piepho pointed out that the pll test i2c transmission is slightly wrong; it was transmitting a zero length message, and then reading from the PLL. This was wrong; it should only be transmitting a single read i2c message. Signed-off-by:

Some cards have multiple possible addresses for their PLLs, with no other way to tell if a PLL is present or not apart from probing to see if an i2c device is present. This adds a quick check to see if an i2c device is present at the given i2c address. Signed-off-by:

V4L/DVB (4028): Change dvb_frontend_ops to be a real field instead of a pointer field inside dvb_frontend The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver is having a field of dvb_frontend_ops in its private-state-struct and using the reference for filling the pointer-field in dvb_frontend. - It saves at least two lines of code per demod-driver, - reduces object size (one less dereference per frontend_ops-access), - be coherent with dvb_tuner_ops, - makes it a little bit easier for newbies to understand how it works and - avoids stupid mistakes because you would have to copy the dvb_frontend_ops always, before you could assign the static pointer directly, which was dangerous.

* nxt200x.c, nxt200x.h - New frontend module that supports both NXT2002 and NXT2004. So far, only tested on NXT2004. After testing on NXT2002, we should deprecate the nxt2002 module, and implement this one instead on the applicable cards. * get_dvb_firmware: - Added support for the NXT2004 firmware. This firmware works with both the ATI HDTV Wonder and the AVerTVHD MCE a180. This was originally written by Jean-Francois Thibert * dvb-pll.c - Fixed minimum frequency for tuv1236d.

It is a small modification to the table that defines the way that the LG-Z201 tuner is controlled for the DVICO Fusion DVB-T1 tuner card. I believe that a mistake was made when the dvb tuner code was reorganised (to use a generic table for the tuner information instead of inline code) and as a result, the DVICO card doesn't tune properly. The modification I have made to the table makes it behave like it did with the old inline tuner code that worked. The patch is on top of the 2.6.12 kernel. Signed-off-by:
