This happens in omap_vout_probe() and vidioc_s_fmt_vid_out(). The calls to omapvid_init(which internally calls set_overlay_info()) are removed from these functions. They don't need to be called as the omap_vout_device struct anyway maintains the overlay related changes made. Also, remove the explicit call to set_overlay_info() in vidioc_streamon(), this was used to set the paddr, this isn't needed as omapvid_init() does the same thing later. These changes are required as the DSS2 driver since 3.3 kernel doesn't let you set the overlay info with paddr as 0.

Functions like rc_keydown() and functions which add/remove entries to the keytable want a single protocol. Future userspace APIs would also benefit from numeric protocols (rather than bitmap ones). Keytables are smaller if they can use a small(ish) integer rather than a bitmap. Other functions or struct members (e.g. allowed_protos, enabled_protocols, etc) accept multiple protocols and need a bitmap. Using different types reduces the risk of programmer error. Using a protocol enum whereever possible also makes for a more future-proof user-space API as we don't need to worry about a sufficient number of bits being available (e.g. in structs used for ioctl() calls). The use of both a number and a corresponding bit is dalso one in e.g. the input subsystem as well (see all the references to set/clear bit when changing keytables for example). This patch separate the different usages in preparation for upcoming patches. Where a single protocol is expected, enum rc_type is used; where one or more protocol(s) are expected, something like u64 is used. The patch has been rewritten so that the format of the sysfs "protocols" file is no longer altered (at the loss of some detail). The file itself should probably be deprecated in the future though.

This is similar to what commit f27b853ea24a9b70585f9251384d97929e6551c3 ("[media] rc: Fix invalid free_region and/or free_irq on probe failure") did for some other drivers. In addition to making the cleanup more consistent, this also fixes a case where (on a ene_hw_detect failure) free_region would be called on a region that was not requested yet. This last problem was probably introduced by the moving of code in commit b31b021988fed9e3741a46918f14ba9b063811db ("[media] ene_ir: Fix driver initialisation") and commit 9ef449c6b31bb6a8e6dedc24de475a3b8c79be20 ("[media] rc: Postpone ISR registration").

The TechNote for mt9v022 (TN0960) and mt9v024 (TN-09-225) describes required register settings when configuring the snapshot operation. The snapshot mode requires that certain automatic functions of the image sensor should be disabled or set to fixed values. According to the TechNote bit 2 and bit 9 in the register 0x20 must be set in snapshot mode and unset for normal operation. This applies for mt9v022 Rev.3 and mt9v024.

+ Streaming I/O (DMA buffer importing) + + + Experimental + This is an experimental + interface and may change in the future. + + +The DMABUF framework provides a generic method for sharing buffers +between multiple devices. Device drivers that support DMABUF can export a DMA +buffer to userspace as a file descriptor (known as the exporter role), import a +DMA buffer from userspace using a file descriptor previously exported for a +different or the same device (known as the importer role), or both. This +section describes the DMABUF importer role API in V4L2. + +Input and output devices support the streaming I/O method when the +V4L2_CAP_STREAMING flag in the +capabilities field of &v4l2-capability; returned by +the &VIDIOC-QUERYCAP; ioctl is set.

Next, +these buffers are exported to the application as file descriptors using an API +which is specific for an allocator driver. Only such file descriptor are +exchanged. The descriptors and meta-information are passed in &v4l2-buffer; (or +in &v4l2-plane; in the multi-planar API case).

Such buffers, may be exported using DMABUF mechanism. If the driver that created a queue is unloaded then the queue is released, the device might be released too. However, buffers cannot be released if they are referenced by DMABUF descriptor(s). The device pointer kept in a buffer must be valid for the whole buffer's lifetime. Therefore MMAP buffers should take a reference to the device to avoid risk of dangling pointers.

The driver exposes a subdev device node for CAMIF pixel resolution and crop control and two video capture nodes - for the "codec" and "preview" data paths. It has been tested on Mini2440 (s3c2440) and Mini6410 (s3c6410) board with gstreamer and mplayer.
