Merge tag 'media/v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - Legacy soc_camera driver was removed from staging

 - New I2C sensor related drivers: dw9768, ch7322, max9271, rdacm20

 - TI vpe driver code was re-organized and had new features added

 - Added Xilinx MIPI CSI-2 Rx Subsystem driver

 - Added support for Infrared Toy and IR Droid devices

 - Lots of random driver fixes, new features and cleanups

+/**
+ * struct cec_adapter - cec adapter structure
+ * @owner:		module owner
+ * @name:		name of the CEC adapter
+ * @devnode:		device node for the /dev/cecX device
+ * @lock:		mutex controlling access to this structure
+ * @rc:			remote control device
+ * @transmit_queue:	queue of pending transmits
+ * @transmit_queue_sz:	number of pending transmits
+ * @wait_queue:		queue of transmits waiting for a reply
+ * @transmitting:	CEC messages currently being transmitted
+ * @transmit_in_progress: true if a transmit is in progress
+ * @kthread_config:	kthread used to configure a CEC adapter
+ * @config_completion:	used to signal completion of the config kthread
+ * @kthread:		main CEC processing thread
+ * @kthread_waitq:	main CEC processing wait_queue
+ * @ops:		cec adapter ops
+ * @priv:		cec driver's private data
+ * @capabilities:	cec adapter capabilities
+ * @available_log_addrs: maximum number of available logical addresses
+ * @phys_addr:		the current physical address
+ * @needs_hpd:		if true, then the HDMI HotPlug Detect pin must be high
+ *	in order to transmit or receive CEC messages. This is usually a HW
+ *	limitation.
+ * @is_configuring:	the CEC adapter is configuring (i.e. claiming LAs)
+ * @is_configured:	the CEC adapter is configured (i.e. has claimed LAs)
+ * @cec_pin_is_high:	if true then the CEC pin is high. Only used with the
+ *	CEC pin framework.
+ * @adap_controls_phys_addr: if true, then the CEC adapter controls the
+ *	physical address, i.e. the CEC hardware can detect HPD changes and
+ *	read the EDID and is not dependent on an external HDMI driver.
+ *	Drivers that need this can set this field to true after the
+ *	cec_allocate_adapter() call.
+ * @last_initiator:	the initiator of the last transmitted message.
+ * @monitor_all_cnt:	number of filehandles monitoring all msgs
+ * @monitor_pin_cnt:	number of filehandles monitoring pin changes
+ * @follower_cnt:	number of filehandles in follower mode
+ * @cec_follower:	filehandle of the exclusive follower
+ * @cec_initiator:	filehandle of the exclusive initiator
+ * @passthrough:	if true, then the exclusive follower is in
+ *	passthrough mode.
+ * @log_addrs:		current logical addresses
+ * @conn_info:		current connector info
+ * @tx_timeouts:	number of transmit timeouts
+ * @notifier:		CEC notifier
+ * @pin:		CEC pin status struct
+ * @cec_dir:		debugfs cec directory
+ * @status_file:	debugfs cec status file
+ * @error_inj_file:	debugfs cec error injection file
+ * @sequence:		transmit sequence counter
+ * @input_phys:		remote control input_phys name
+ *
+ * This structure represents a cec adapter.
