VIDIOC_TRY_FMT shouldn't fail if the user requests an unsupported pixel format. Instead the driver should replace it with a supported one. Fix the sh_mobile_ceu_camera driver accordingly. Signed-off-by:

The recently introduced .enum_mbus_fsizes() v4l2-subdev video operation is a duplicate of the .enum_framesizes() operation, introduced earlier. Switch soc-camera over to using the original one. Signed-off-by:

In mx2_camera_try_fmt(), when applying i.MX25 restrictions to frame sizes, the height is checked to be <= 0xffff. But later an integer multiplication height * 4 * 0x3ffff is performed, which will overflow even for bounded height values. This patch switches to using 64-bit multiplication and division to avoid overflowing. Signed-off-by:

Add a capabilities field to the soc_camera_host structure to flag hosts that support user-configurable line strides. soc_camera_try_fmt() then passes the user-provided bytesperline and sizeimage format fields to such hosts, and expects the host to check (and fix if needed) the values.

The V4L2 specification defines bytesperline for planar formats as the number of bytes per line for the largest plane. Modify soc_mbus_bytes_per_line() accordingly. Signed-off-by:

To compute the value of the v4l2_pix_format::bytesperline field, we need information about planes layout for planar formats. The new enum soc_mbus_layout conveys that information. Signed-off-by:

The try_fmt() handler restricts the image width based on the hardware limits and updates the bytesperline value, but doesn't update sizeimage. Fix it. Signed-off-by:

In 'dib0700_i2c_xfer_new()' and 'dib0700_i2c_xfer_legacy()' we are taking two locks: 1. i2c_mutex 2. usb_mutex If attempt to take 'usb_mutex' lock fails then the previously taken lock 'i2c_mutex' should be unlocked and -EINTR should be returned so that caller can take appropriate action. If locking attempt was interrupted by a signal then we should return -EINTR. At present we are returning '0' for such scenarios which is wrong. Replace -EAGAIN by -EINTR as a return type for the the scenario where locking attempt was interrupted by signal. Signed-off-by:Santosh Nayak <santoshprasadnayak@gmail.com> Signed-off-by:

MPIS based STBs running 3.x kernels and the Enigma2 OS are not able to tune DVB-T channels with the PCTV 290e using the current cxd2820r driver. DVB-T2 channels instead work properly. This patch fixes the problem by changing the condition to break out from the wait lock loop in the "search" function of the cxd2820r demodulator from FE_HAS_SIGNAL to FE_HAS_LOCK. As a consequence, the "search" function of the demodulator driver now returns DVBFE_ALGO_SEARCH_SUCCESS only if the frequency lock is successfully acquired. This behavior seems consistent with other demodulator drivers (e.g. stv090x, hd29l2, stv0900, stb0899, mb86a16). This patch has been successfully tested with DVB-T and DVB-T2 signals, on both PC and the mipsel STB running Enigma2. No apparent side effect has been observed on PC applications like Kaffeine. DVB-C is not available in my country so it's not tested. Signed-off-by:

Enable the LNA amplifier also for DVB-T (like for DVB-T2 and DVB-C); this greatly improves reception of weak signals without affecting the reception of the strong ones. Experimental data (collected with the mipsel STB) on the weakest frequencies available in my area: LNA OFF: MUX level BER picture RAI mux 4 72% 32000 corrupted TIMB 2 75% 14 OK TVA Vicenza 68% 32000 corrupted RAI mux 2 78% 14 OK LNA ON: MUX level BER picture RAI mux 4 73% 1500 OK TIMB 2 76% 0 OK TVA Vicenza 69% 0 OK RAI mux 2 79% 0 OK Moreover, with LNA enabled, the PCTV 290e was able to pick up 2 new frequencies matching the integrated tuner of my Panasonic G20 TV, which is really good.

As reported by Masanari, this macro is using "KERN_ERR" instead of "KERN_ERROR". That would lead into a compilation breakage, if this macro were used somewhere inside the driver. Instead of fixing the macro, as originally proposed, let's just remove the dead code. Reported-by:
