Antti,Attached is a patch that fixed all but one v4l2-compliance error: fail: v4l2-test-controls.cpp(295): returned control value out of range fail: v4l2-test-controls.cpp(357): invalid control 00a2090c test VIDIOC_G/S_CTRL: FAIL fail: v4l2-test-controls.cpp(465): returned control value out of range fail: v4l2-test-controls.cpp(573): invalid control 00a2090c test VIDIOC_G/S/TRY_EXT_CTRLS: FAIL That's the BANDWIDTH control and it returned value 3200000 when the minimum was 6000000. I couldn't trace where that came from in the limited time I spent on it, I expect you can find it much quicker.
That is because I added native V4L2_CID_RF_TUNER_BANDWIDTH support only for E4000 tuner driver. The others, FC0012, FC0013 and R820T are set via DVB API by rtl2832_sdr driver, which is quite hackish solution. Devices having E4000 works correctly.
Dunno if it wise to hack rtl2832_sdr and clamp values to valid per tuner or leave it as it is. Adding V4L2_CID_RF_TUNER_BANDWIDTH to those 3 tuner drivers is also quite trivial...
