Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by:

GIT_AUTHOR_DATE=1376465691 I took a quick look at the code and wonder if the problem is caused by an initial zero statistics message? This is all just a wild guess, but if it is correct, then the attached untested patch might fix it...

Those boards were missing the ISDB-T support. Most of the work on this patch were done by Alfredo. My work here were to port this patch from Kernel 3.2 to upstream, fix the issue caused by the set_frontend bad hook, and add the Kconfig bits. Tested on a X8502 board rebranded as: "Leadership - Placa PCI-e de Captura de Vídeo Híbrida" - product code 3800. Thanks-to: Alfredo Delaiti <alfredodelaiti@netscape.net> Tested-by:

When the frontend drivers got converted to DVBv5 API, the original hook that tracked when a frontend is set got removed, being replaced by an approach that would use the gate control. That doesn't work fine with some boards. Also, the code were called more times than desired. Replace it by a logic that will hook the dvb set_frontend ops, with works with both DVBv3 and DVBv5 calls. Tested on a Mygica X8502 OEM board. Tested-by:

Hello, this is a new gspca driver for Syntek STK1135 webcams. The code is completely new, but register values are based on Syntekdriver (stk11xx) by Nicolas VIVIEN (http://syntekdriver.sourceforge.net). Only one webcam type is supported now - vendor 0x174f, device 0x6a31. It's Asus F5RL laptop flippable webcam with MT9M112. The camera works better than in Windows - initializes much faster and provides more resolutions (the sensor can do almost any resolution - just add it to the stk1135_modes[] - could this feature be somehow used by applications to avoid SW scaling?). Autoflip works too - when the camera is flipped around, the image is flipped automatically. Signed-off-by:

It is not sure what is meaning of that number, but it is better to try do as Windows driver. It seems to have small effect for signal when looking FM FFT. Signed-off-by:

That one seems to have 14-bit ADC resolution, wow! It is now used when sampling rate is below 6 Msps. Signed-off-by:

Allow stepless synthesizer configuration. With that change we lose precision a little bit, as it is now between +-500Hz from the target. It could be better but on that case calculation algorithm goes more complex and atm there is more important things to do. Two approach to improve which comes to my mind are: 1) select and use biggest suitable step 2) use greatest common divisor algo to find divisor for thresh & frac when possible to avoid rounding errors, which is root of cause of current +-500Hz inaccuracy.

No need to compare numbers, we could just store that fractional value MSB directly. Signed-off-by:

Restarting stream fails quite often. Small delay is between urb killing and stream stop command - likely to give harware some time to process killed urbs. Signed-off-by:

It looks like there is some extra data carried to enhance sampling results. When you tune to some some weak/empty channel those bits are always zeroes. When you tune to some channel where is very strong signals those bits are all zeroes. Examining those 32-bits reveals shortly there is 16 pieces of 2-bit numbers. Number seen are 0, 1 and 3 - for some reason 2 is not used. I used that number to shift bits given amount to left, "increasing" sampling resolution by 3-bits. It may be wrong, but after some testing it still provides better signal. Signed-off-by:

Whilst Quadrature Sampling is most common sampling technique used in radio technology there is others too. Add control user could select sampling mode. We currently support only quadrature sampling. Signed-off-by:

These calculations seem to give 100% correct results. Calculation formulas could be still a little bit wrong as I have no knowledge what kind of dividers, multipliers and VCO limits there really is. Signed-off-by:
