If cec_notifier_cec_adap_unregister() is called before cec_unregister_adapter() then everything is OK (and this is the case today). But if it is the other way around, then cec_notifier_unregister() is called first, and that doesn't set n->cec_adap to NULL. So if e.g. cec_notifier_set_phys_addr() is called after cec_notifier_unregister() but before cec_unregister_adapter() then n->cec_adap points to an unregistered and likely deleted cec adapter. So just set n->cec_adap->notifier and n->cec_adap to NULL for rubustness. Eventually cec_notifier_unregister will disappear and this will be simplified substantially. Signed-off-by:

Check if cec_s_conn_info is called with a valid cec adapter, do nothing if it is invalid. This makes it possible to call this function even if CEC support is disabled in the kernel config. Signed-off-by:

The older CSI drivers have camera capture interface different from the one in the newer ones. This IP is pretty simple. Some variants (one controller out of two instances on some SoCs) have an ISP embedded, but there's no code that make use of it, so we ignored that part for now.

The Makefile and Kconfig for the sun6i CSI driver are included in the main Makefile / KConfig file. Since we're going to add a new CSI driver for an older chip, and the Cedrus driver eventually, it makes more sense to put those in our directory. Signed-off-by:

The Allwinner A10 CMOS Sensor Interface is a camera capture interface also used in later (A10s, A13, A20, R8 and GR8) SoCs. On some SoCs, like the A10, there's multiple instances of that controller, with one instance supporting more channels and having an ISP.

In case of sensor malfunction, stop streaming timeout takes much longer than expected. This is due to conversion of time to jiffies: milliseconds multiplied with HZ (ticks/second) gives out a value of jiffies with 10^3 greater. We need to also divide by 10^3 to obtain the right jiffies value. In other words FRAME_INTERVAL_MILLI_SEC must be in seconds in order to multiply by HZ and get the right jiffies value to add to the current jiffies for the timeout expire time.

commit 5fa88151 ("[media] dvb-usb-cxusb: Geniatech T230 - resync TS FIFO after lock") does not solve the problem for all devices. This is the same issue reported on the T230C, which was moved to the dvbsky.c driver to work around this issue in commit 57422405 ("media: dvbsky: MyGica T230C support"). In addition, the cxusb driver causes an oops when unplugging the device while streaming; this problem does not happen any more. Signed-off-by:

Fix and eliminate mceusb's IR length limit for IR signals transmitted to the MCE IR blaster ports. An IR signal TX exceeding 306 pulse/space samples presently causes -EINVAL return error. There's no such limitation nor error with the MCE device hardware. And valid IR signals exist with more than 400 pulse/space for the control of certain appliances (eg Panasonic ACXA75C00600 air conditioner). The scope of this patch is limited to the mceusb driver. There are still IR signal TX length and time constraints that related modules of rc core (eg LIRC) impose, further up the driver stack. Changes for mceusb_tx_ir(): Converts and sends LIRC IR pulse/space sequence to MCE device IR pulse/space format. Break long length LIRC sequence into multiple (unlimited number of) parts for sending to the MCE device. Reduce kernel stack IR buffer size: 128 (was 384) Increase MCE IR data packet size: 31 (was 5) Zero time LIRC pulse/space no longer copied to MCE IR data. Eliminate overwriting the source/input LIRC IR data in txbuf[]. Eliminate -EINVAL return; return number of IR samples sent (>0) or MCE write error code (<0). New mce_write() and mce_write_callback(): Implements synchronous blocking I/O, with timeout, for writing/sending data to the MCE device. An unlimited multipart IR signal sent to the MCE device faster than real time requires flow control absent with the original mce_request_packet() and mce_async_callback() asynchronous I/O implementation. Also absent is TX error feedback. mce_write() combines and replaces mce_request_packet() and mce_async_callback() with conversion to synchronous I/O. mce_write() returns bytes sent (>0) or MCE device write error (<0). Debug hex dump TX data before processing. Rename mce_async_out() -> mce_command_out(): The original name is misleading with underlying synchronous I/O implementation. Function renamed to mce_command_out(). Changes in mceusb_handle_command(): Add support for MCE device error case MCE_RSP_TX_TIMEOUT "IR TX timeout (TX buffer underrun)" Changes in mceusb_dev_printdata(): Changes support test and debug of multipart TX IR. Add buffer boundary information (offset and buffer size) to TX hex dump. Correct TX trace bug "Raw IR data, 0 pulse/space samples" Add trace for MCE_RSP_TX_TIMEOUT "IR TX timeout (TX buffer underrun)" Other changes: The driver's write to USB device architecture change (async to sync I/O) is significant so we bump DRIVER_VERSION to "1.95" (from "1.94").

Due to complexity of the video decoding process, the V4L2 drivers of stateful decoder hardware require specific sequences of V4L2 API calls to be followed. These include capability enumeration, initialization, decoding, seek, pause, dynamic resolution change, drain and end of stream. Specifics of the above have been discussed during Media Workshops at LinuxCon Europe 2012 in Barcelona and then later Embedded Linux Conference Europe 2014 in Düsseldorf. The de facto Codec API that originated at those events was later implemented by the drivers we already have merged in mainline, such as s5p-mfc or coda. The only thing missing was the real specification included as a part of Linux Media documentation. Fix it now and document the decoder part of the Codec API. Signed-off-by:

Add an enum_fmt format flag to specifically tag coded formats where dynamic resolution switching is supported by the device. This is useful for some codec drivers that can support dynamic resolution switching for one or more of their listed coded formats. It allows userspace to know whether it should extract the video parameters itself, or if it can rely on the device to send V4L2_EVENT_SOURCE_CHANGE when such changes are detected. Signed-off-by:

Add an enum_fmt format flag to specifically tag coded formats where full bytestream parsing is supported by the device. Some stateful decoders are capable of fully parsing a bytestream, but others require that userspace pre-parses the bytestream into frames or fields (see the corresponding pixelformat descriptions for details). If this flag is set, then this pre-parsing step is not required (but still possible, of course). Signed-off-by:

Some decoders use intra slice/frame references. The capture buffer pointed by these references might be new and thus have invalid timestamp which prevents the decoder logic from retrieving the vb2_buffer object based on the output buf timestamp. Copy all metadata (including the timestamp) before starting the decode operation. Suggested-by:
