Hi everyone, Here's a series to add basic support for the Techwell TW9900 low-power video decoder. This decoder support PAL, NTSC and SECAM inputs, with a built-in comb filter and automatic input standard detection. This series was based on previous work done by Rockchip, and is based on vendor code. I apologise if there are some rough edges remaining in this driver, as I'm not yet fully familiar with the media and V4L2 frameworks, so any review is appreciated. This series adds basic support for NTSC and PAL B/D/G/H/I, along with some very basic controls for brightness and contrast.
