+ * DOC: Analog TV Connector Properties
+ *
+ * TV Mode:
+ *	Indicates the TV Mode used on an analog TV connector. The value
+ *	of this property can be one of the following:
+ *
+ *	NTSC:
+ *		TV Mode is CCIR System M (aka 525-lines) together with
+ *		the NTSC Color Encoding.
+ *
+ *	NTSC-443:
+ *
+ *		TV Mode is CCIR System M (aka 525-lines) together with
+ *		the NTSC Color Encoding, but with a color subcarrier
+ *		frequency of 4.43MHz
+ *
+ *	NTSC-J:
+ *
+ *		TV Mode is CCIR System M (aka 525-lines) together with
+ *		the NTSC Color Encoding, but with a black level equal to
+ *		the blanking level.
+ *
+ *	PAL:
+ *
+ *		TV Mode is CCIR System B (aka 625-lines) together with
+ *		the PAL Color Encoding.
+ *
+ *	PAL-M:
+ *
+ *		TV Mode is CCIR System M (aka 525-lines) together with
+ *		the PAL Color Encoding.
+ *
+ *	PAL-N:
+ *
+ *		TV Mode is CCIR System N together with the PAL Color
+ *		Encoding, a color subcarrier frequency of 3.58MHz, the
+ *		SECAM color space, and narrower channels than other PAL
+ *		variants.
+ *
+ *	SECAM:
+ *
+ *		TV Mode is CCIR System B (aka 625-lines) together with
+ *		the SECAM Color Encoding.
+ *
+ *	Drivers can set up this property by calling
+ *	drm_mode_create_tv_properties().
