    ENGR00215041-2 MX6 SabreSD:Set clko parent to be clko2 · b4963f50
    Liu Ying authored
    On MX6 SabreSD board, gpio_0 is muxed to clko to be
    audio mclk and camera mclk. 24MHz osc clk is a stable
    clock source, which can meet the requirement of audio
    mclk and camera mclk. This patch sets clko parent
    clock to be clko2 clock so that camera mclk and audio
    mclk can source from osc clk.
    There are 2 benifits after applying this patch:
    1) clko's original parent clock(pll4_audio_main_clk)
    can be gated off to save power or used by another
    2) ov5640/ov5642 camera most settings can reach
    claimed 15fps or 30fps with no human eye recognizable
    video quality downgrade.
