| | | | | | | | | | | The v4l2_of_parse_endpoint function kernel-doc says that the return value is always 0. But that is not true since the function can fail and a error negative code is returned on failure. So correct the kernel-doc to match.

* [media] rtl28xxu: retry failed i2c messagesAntti Palosaari2016-02-011-0/+8
| | | | | | | | | | | | | | Sometimes i2c transfer fails. That happens especially when large amount of data is written sequentially eg. firmware download. Problem arises with both integrated rtl2832 demod and external mn88472 demod, which is clear indicator it is busy i2c bus issue. Use i2c core retry logic in order fix the issue by repeating failed message. Another solution which also works is to add ~100us delay between i2c messages - but repeating sounds more elegant and does not cause any extra delay for success cases.

| | | | | | | | | | | | | | | | | | | | Only handle an interrupt if at least one combination of event bit and related interrupt bit is set. Previously it was just checked that at least one event bit and at least one interrupt bit are set. This fixes issues like the following which was caused by interrupt sharing: An interrupt intended for nvt_cir_isr was handled by nvt_cir_wake_isr first and because status bit CIR_WAKE_IRSTS_IR_PENDING was set the wake fifo was accidently cleared. This patch also fixes the bug that nvt_cir_wake_isr returned IRQ_HANDLED even if it detected that the (shared) interrupt was meant for another handler.

* [media] vivid: fix broken Bayer text renderingHans Verkuil2016-02-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | Sometimes when a Bayer pixelformat is selected the rendering of the OSD text by vivid was all wrong: every other line of the text was shifted by half the width or more. It turned out that to render Bayer formats the interleaved boolean is set to true in the tpg. This mode indicates a semi-biplanar mode where two interleaved planes are used to render the frame. From outside the tpg it looks like a single plane, but internally it is two planes. However, in the tpg_s_bytesperline() function the interleaved bool wasn't checked and only the bytesperline value for plane 0 was updated. But for the interleaved mode the same value has to be copied to bytesperline[1] as well. The effect was that whatever old value was left in bytesperline[1] was used, which caused all sorts of weird and seemingly unpredictable shifts.

* [media] usbtv: discard redundant video fieldsNikola Forró2016-02-012-14/+20
| | | | | | | | | | | | | | | There are many dropped fields with some sources, leading to many redundant fields without counterparts. When this redundant field is odd, a new frame is pushed containing this odd field interleaved with whatever was left in the buffer, causing video artifacts. Do not push a new frame after processing every odd field, but do it only after those which come after an even field.
