3  * cec-pin.h - low-level CEC pin control
15  * struct cec_pin_ops - low-level CEC pin operations
16  * @read:	read the CEC pin. Return true if high, false if low.
17  * @low:	drive the CEC pin low.
18  * @high:	stop driving the CEC pin. The pull-up will drive the pin
19  *		high, unless someone else is driving the pin low.
25  * @read_hpd:	read the HPD pin. Return true if high, false if low or
26  *		an error if negative. If NULL or -ENOTTY is returned,
28  * @read_5v:	read the 5V pin. Return true if high, false if low or
29  *		an error if negative. If NULL or -ENOTTY is returned,
37 	void (*low)(struct cec_adapter *adap);  member
48  * cec_pin_changed() - update pin state from interrupt
51  * @value:	when true the pin is high, otherwise it is low
59  * cec_pin_allocate_adapter() - allocate a pin-based cec adapter
61  * @pin_ops:	low-level pin operations
62  * @priv:	will be stored in adap->priv and can be used by the adapter ops.
