+ * 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

+ *
+ * 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().
