File operations that manipulate the state of the encoder, or video or audio subdevices or some of the stream flags need to be serialized. Add the serilization locks to cx18-alsa in a manner consistent with the locking for the v4l2 file operations. Signed-off-by:

If CX25840_VIN1_CH1 and the like is used, input is not detected as composite. Their value is 0x800000XX and CX25840_COMPONENT_ON is 0x80000200. So 739 else if ((vid_input & CX25840_COMPONENT_ON) == 0) this condition never be true. Signed-off-by:

When using VIDIOC_QBUF with memory type set to V4L2_MEMORY_MMAP, the v4l2_buffer buffer gets unmodified on drivers like uvc (well, only bytesused field is modified). Then some apps like gstreamer are reusing the same buffer later to call munmap (eg passing the buffer "length" field as 2nd parameter of munmap). It's working fine on full 32bits but on 32bits systems with 64bit kernel, the get_v4l2_buffer32() doesn't copy length/m.offset values and then copy garbage to userspace in put_v4l2_buffer32(). This has for consequence things like that in the libv4l2 logs: libv4l2: v4l2 unknown munmap 0x2e2b0000, -2145144908 libv4l2: v4l2 unknown munmap 0x2e530000, -2145144908 The buffer are not unmap'ed and then if the application close and open again the device, it won't work and logs will show something like: libv4l2: error setting pixformat: Device or resource busy The easy solution is to read length and m.offset in get_v4l2_buffer32().

Before each FCP transdaction, the entire 512 bytes of the FCP frame were cleared, then values filled in. Clear only the bytes between filled-in bytes and end of the - request frame, or - response frame if data from a larger response will be needed, or - whole frame if data from a variable length response will be taken.

FCP transactions as well as CMP transactions were serialized with mutex_lock_interruptible. It is extremely unlikly though that a signal will arrive while a concurrent process holds the mutex. And even if one does, the duration of a transaction is reasonably short (1.2 seconds if all retries time out, usually much shorter). Hence simplify the code to plain mutex_lock. Signed-off-by:

This is a portability fix and reduces stack usage. The DMA mapping API cannot map on-stack addresses, as explained in Documentation/DMA-mapping.txt. Convert the two cases of on-stack packet payload buffers in firedtv (payload of write requests in avc_write and of lock requests in cmp_lock) to slab-allocated memory. We use the 512 bytes sized FCP frame buffer in struct firedtv for this purpose. Previously it held only incoming FCP responses, now it holds pending FCP requests and is then overwriten by an FCP response from the tuner subunit. Ditto for CMP lock requests and responses. Accesses to the payload buffer are serialized by fdtv->avc_mutex. As a welcome side effect, stack usage of the AV/C transaction functions is reduced by 512 bytes. Alas, avc_register_remote_control() is a special case: It previously did not wait for a response. To fit better in with the other FCP transactions, let it wait for an interim response. Signed-off-by:

1) clocks are configured using generic clock names 2) converting the driver to a platform driver 3) cleanup - consolidate all static variables inside a structure, ccdc_cfg The ccdc driver now uses generic names for clocks - master and slave. On individual platforms these clocks will inherit from the platform specific clock. This will allow re-use of the driver for the same IP across different SoCs. Reviewed-by:
