2007-04-27V4L/DVB (5427): M920x: Improve I2C operationsTrent Piepho
Write some better documentation about what might be known about how the m920x I2C works, since a datasheet is lacking. The I2C xfer function should now handle more types of I2C transactions than it could before. Those it can't, will return error codes instead of being executed incorrectly. Multi-byte reads were not being done correctly, which should be fixed. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-04-27V4L/DVB (5420): Initialize the inputs before registering the devices.Hans Verkuil
Once the devices have been registered anyone can start changing the inputs or TV standard before they have been initialized by the driver. This leads to cases were the input is changed in an udev rule, but after that rule is triggered the tail-end of the ivtv driver initialization can override that by selecting the tuner input. The correct sequence is to first setup the input, initial frequency and TV standard before finally registering the video devices. This prevents any udev rules from being triggered prematurely.

2007-04-27V4L/DVB (5374): Or51132: refactor i2c code, improve error resilienceTrent Piepho
The code the i2c transactions was leftover from the old V4L-based ATSC driver. It did too little with too much code. It is re-written to remove unnecessary parameters and be more efficient. A demod register can now be read with one function call, instead of repeating a dozen line block of code each time. There were msleep()'s, which appear to be unnecessary, spread around all the I2C transactions. These have been removed. Reading SNR used to take about 130 ms, now it's down to 1.8 ms. Reads from the demodulator's registers do not return correct results sometimes. Adding or removing the delays in the I2C transactions did not appear to effect the probability of failure. If anything, the transactions without delays were less likely to fail, but since far more transactions could be made per second the number of failures per hour was greater. To increase reliability, the SNR and get_params functions will now retry once if they get bad data back. This appears to have reduced the probability of failure to effectively zero. Some error messages are cleaned up or given KERN_* levels when they were missing. or51132_setmode() wasn't returning correct error codes, which is fixed as well.

The attached patch fixes this problem by removing two lines in dib0700_ctrl_rd() that try to correct the endianess on two values that already are correct: - /* think about swapping here */ - value = le16_to_cpu(value); - index = le16_to_cpu(index); With this simple patch this dvb hardware works great, thanks to anyone involved for the good work. :) Signed-off-by: Dennis Ranke <mail@exoticorn.de> Signed-off-by: Patrick Boettcher <pb@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-04-27V4L/DVB (5363): Dvb: Remove lgh06xf driverTrent Piepho
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.

2007-04-27V4L/DVB (5362): Dvb-pll: add code for doing tuner initializationTrent Piepho
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.

2007-04-27V4L/DVB (5361): Dvb-pll: Fix Kconfig files and allow dvb-pll to be optionalTrent Piepho
A number of drivers selected DVB_PLL when they did not need it, and some that did need it did not select it. The DVB_PLL option is given a name and help text, so that it will show up in the config menu. DVB_PLL support can be turned on if an out-of-tree driver needs it. The standard dvb fe customization support is added to dvb-pll.h. Since all modules which select DVB_PLL do so unconditionally, it is not possible to turn dvb-pll off when an enabled module selects it, unlike most of the other frontend/tuner drivers. This is because the users of dvb-pll have static references to dvb-pll symbols other than the attach function. If these references are removed, then dvb-pll will be disablable as the other frontend/tuner drivers are.
