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. Signed-off-by:

Check for the case that no Nuvoton chip is found on either EFM port. Also move the position of nvt_efm_disable to reduce the time the EFM ports are locked. Signed-off-by:

The v4l2-common.h user space header was split off from videodev2.h, but the dual licensing of the videodev2.h (as well as other V4L2 headers) was missed. Change the license of the v4l2-common.h from GNU GPL v2 to both GNU GPL v2 and BSD.

The Camera Adaptation Layer (CAL) is a block which consists of a dual port CSI2/MIPI camera capture engine. Port #0 can handle CSI2 camera connected to up to 4 data lanes. Port #1 can handle CSI2 camera connected to up to 2 data lanes. The driver implements the required API/ioctls to be V4L2 compliant. Driver supports the following: - V4L2 API using DMABUF/MMAP buffer access based on videobuf2 api - Asynchronous sensor sub device registration - DT support Signed-off-by:Benoit Parrot <bparrot@ti.com> Signed-off-by:

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. Reported-by:

A driver might detect a new standard or DV timings, but it will never change to those new timings automatically. Instead it will send an event and let the application take care of it. Make this explicit in the documentation. Signed-off-by:

i2c_wr() is called from ops and the interrupt service routine, while state->wr_data is shared and unprotected, and could be overwritten. This shared buffer is therefore replaced with a local array with fixed size. The array has the size of one EDID block (128 bytes) + 2 bytes i2c address, and the EDID is written block by block (up to 8 blocks). Signed-off-by:

During the recent vb2_buffer restructuring, the calculation of the buffer payload reported to userspace was accidentally broken for the first encoded frame, counting only the length of the headers. This patch re-adds the length of the actual frame data. Fixes: 2d700715 ("[media] media: videobuf2: Restructure vb2_buffer") Reported-by:

This issue was detected by using the Coccinelle software. 1. Let us return directly if a buffer allocation failed. 2. Delete the jump label "err" then. 3. Drop the explicit initialisation for the variable "ret" at the beginning. 4. Return zero as a constant at the end. Signed-off-by:

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. Signed-off-by:
