2011-07-28[media] xc4000: added audio_std module parameterIstvan Varga1-0/+23
The 'audio_std' module parameter makes it possible to fine tune some audio related aspects of the driver, like setting the exact audio standard (NICAM, A2, etc.) to be used for some video standards.

2011-07-28[media] xc4000: setting registersIstvan Varga1-12/+55
This patch implements setting the registers in xc4000_set_params() and xc4000_set_analog_params(). A new register is defined which enables filtering of the composite video output (this is needed to avoid bad picture quality with some boards).

2011-07-28[media] xc4000: fixed frequency errorIstvan Varga1-2/+3
The xc_get_frequency_error() function reported the frequency error incorrectly. The data read from the hardware is a signed integer, in 15625 Hz units. The attached patch fixes the bug. Signed-off-by: Istvan Varga <istvan_v@mailbox.hu> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-28[media] xc4000: added mutexIstvan Varga1-30/+50

2011-07-28[media] dib0700: fixup PLL config for PCTV 340eDevin Heitmueller1-1/+41
Based on a reference trace under Windows, reverse engineer the PLL config. Note that the xtal is not yet setup, and the timf cannot be determined yet because my reference trace doesn't actually achieve a signal lock.

2011-07-28[media] xc4000: handle dib0700 broken i2c stretchingDevin Heitmueller1-5/+29
It was confirmed by DibCom that i2c stretching is broken in the i2c master on the dib7700. So we need to put a hack into the xc4000 driver to not complain in certain very specific cases where we know i2c stretching occurs.

2011-07-28[media] xc4000: continued cleanup of the firmware loading routineDevin Heitmueller1-136/+44
Properly setup the standard firmware loading and scode loading, as well as getting rid of a ton of dead code. Note that I am getting a single i2c error when the standard firmware sets the video standard, but everything else seems to be loading properly now.

2011-07-28[media] xc4000: add code to do standard and scode firmware loadingDevin Heitmueller1-9/+332
Add code to handle firmware blobs for the standard and scode. Note there appears to be some issue with loading the DTV8 standard firmware, probably related to direct/indirect mode.

2011-07-28[media] xc4000: remove xc5000 firmware loading routineDevin Heitmueller1-2/+0
Since we use the xc3028 version of the firmware file parsing routine (which includes support for scodes and separate blobs), we can drop the xc5000 version of the code. Signed-off-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-28[media] xc4000: remove XREG_BUSY code only supported in xc5000Devin Heitmueller1-26/+0
The xc4000 driver is based on the original xc5000 driver, and while the xc5000 supports the XREG_BUSY register, the xc4000 does not. So remove the code in question. Signed-off-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-28[media] xc4000: properly set type for init1 firmwareDevin Heitmueller1-1/+1
We need to set the firmware type properly in order to locate the init1 firmware. Signed-off-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-28[media] xc4000: cut over to using xc5000 version for loading i2c sequencesDevin Heitmueller1-90/+5
The xc3028 version does i2c splitting in a different manner than xc4000 and xc5000, so reuse the xc5000 version of the routine (the key here being that xc4000 expects the first *two* bytes to be the same for splitting transactions. Doing it the xc3028 way was resulting in i2c errors partially through the firmware load. With this change, it would appear that the entire base firmware is being loaded successfully (product id now properly shows 0x0FA0).

2011-07-28[media] xc4000: pull in firmware management code from xc3028Devin Heitmueller1-31/+393
Switch over to using the firmware management routines from the tuner-xc2028, since that has support for scodes, etc. This code still requires signficant cleanup, and at this point the base firmware does not load properly (i2c write errors about 300 bytes in).

2011-07-28[media] dib7000p: setup dev.parent for i2c master built into 7000pDevin Heitmueller1-0/+5
We need to set the dev.parent member on the dib7000p on its i2c master, or else calls to request_firmware() will hit an oops in 2.6.31.

2011-07-28[media] mt9v011: Fixed gain calculationJohannes Obermaier1-11/+52
The implementation of the gain calculation for this sensor is incorrect. It is only working for the first 127 values. The reason is, that the gain cannot be set directly by writing a value into the gain registers of the sensor. The gain register work this way (see datasheet page 24): bits 0 to 6 are called "initial gain". These are linear. But bits 7 and 8 ("analog multiplicative factors") and bits 9 and 10 ("digital multiplicative factors") work completely different: Each of these bits increase the gain by the factor 2. So if the bits 7-10 are 0011, 0110, 1100 or 0101 for example, the gain from bits 0-6 is multiplied by 4. The order of the bits 7-10 is not important for the resulting gain. (But there are some recommended values for low noise) The current driver doesn't do this correctly: If the current gain is 000 0111 1111 (127) and the gain is increased by 1, you would expect the image to become brighter. But the image is completly dark, because the new gain is 000 1000 0000 (128). This means: Initial gain of 0, multiplied by 2. The result is 0. This patch adds a new function which does the gain calculation and also fixes the same bug for red_balance and blue_balance. Additionally, the driver follows the recommendation from the datasheet, which says, that the gain should always be above 0x0020.

2011-07-28[media] mt9v011: Added exposure for mt9v011Johannes Obermaier1-1/+21
There are problems when you use this camera/sensor in a very bright room or outside. The image is completely white, because it is overexposed. The driver uses a default value which is not suitable for all environments. This patch makes it possible to adjust the exposure time by youself. I found out by logging the i2c-data, that the windows driver for this sensor is doing this, too. I tested the camera on a sunny day and after adjusting the exposure time, I was able to see a very good image.
