+ * struct rc_dev - represents a remote control device
+ * @dev: driver model's view of this device
+ * @input_name: name of the input child device
+ * @input_phys: physical path to the input child device
+ * @input_id: id of the input child device (struct input_id)
+ * @driver_name: name of the hardware driver which registered this device
+ * @map_name: name of the default keymap
+ * @rc_tab: current scan/key table
+ * @devno: unique remote control device number
+ * @raw: additional data for raw pulse/space devices
+ * @input_dev: the input child device used to communicate events to userspace
+ * @driver_type: specifies if protocol decoding is done in hardware or software
+ * @idle: used to keep track of RX state
+ * @allowed_protos: bitmask with the supported IR_TYPE_* protocols
+ * @scanmask: some hardware decoders are not capable of providing the full
+ * scancode to the application. As this is a hardware limit, we can't do
+ * anything with it. Yet, as the same keycode table can be used with other
+ * devices, a mask is provided to allow its usage. Drivers should generally
+ * leave this field in blank
+ * @priv: driver-specific data
+ * @keylock: protects the remaining members of the struct
+ * @keypressed: whether a key is currently pressed
+ * @keyup_jiffies: time (in jiffies) when the current keypress should be released
+ * @timer_keyup: timer for releasing a keypress
+ * @last_keycode: keycode of last keypress
+ * @last_scancode: scancode of last keypress
+ * @last_toggle: toggle value of last command
+ * @timeout: optional time after which device stops sending data
+ * @min_timeout: minimum timeout supported by device
+ * @max_timeout: maximum timeout supported by device
+ * @rx_resolution : resolution (in ns) of input sampler
+ * @tx_resolution: resolution (in ns) of output sampler
+ * @change_protocol: allow changing the protocol used on hardware decoders
+ * @open: callback to allow drivers to enable polling/irq when IR input device
+ * is opened.
+ * @close: callback to allow drivers to disable polling/irq when IR input device
+ * is opened.
+ * @s_tx_mask: set transmitter mask (for devices with multiple tx outputs)
+ * @s_tx_carrier: set transmit carrier frequency
+ * @s_tx_duty_cycle: set transmit duty cycle (0% - 100%)
+ * @s_rx_carrier: inform driver about carrier it is expected to handle
+ * @tx_ir: transmit IR
+ * @s_idle: enable/disable hardware idle mode, upon which,
+ * device doesn't interrupt host until it sees IR pulses
+ * @s_learning_mode: enable wide band receiver used for learning
+ * @s_carrier_report: enable carrier reports
