In this patch we introduce PAL and SECAM formats available and create seting-format property at init time. When user dynamically chose preferred format by xrandr command, it will refine all modelines provided by SDVO device, then instruct SDVO device to execute. At the same time the property is added for SDVO-TV so that the SDVO-TV mode can be changed by using xrandr. https://bugs.freedesktop.org/show_bug.cgi?id=22891 Signed-off-by: Ma Ling review-by: Zhao Yakui --- Due to multiple sdvo encoder patch have two versions: dynamically or statically construct encoder functions.
