They're split in categories, each of them having multiple variants called styles. The styles are just numbered 1, 2 and 3 in the tables that describe the formats, and there's a register field used to select a style. For some reason style 1 maps to register value 2, style 2 to register value 1, and style 3 to register value 3. Go figure... -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
