 * (2) Power down PD of Cluster0
 *
 * But we have problem at step (2), Cluster0 is attached to VP0. but VP0

 * According to IC designer: We must power down all internal PD of VOP

 * So we get this workaround:
 * We we found a VP is in standby mode when we want power down a PD is

 * run a default timing and generate vsync. Than we can power down the

 *
 * 2. When a video port connect both hdmi0 and hdmi1(may also connect other output interface),

 *    is under 4K@60Hz, set the video port dlk parent as hdmi0 phy pll.if hdmi0 or hdmi1 phy pll
 *    is used by other video port, report a error.
 *
 * 3. When a video port(A) connect hdmi0(may also connect other output interface but not hdmi1),
 *    it must hold the hdmi0 phy pll, and other video port can't use it. If both hdmi0 and hdmi1
 *    phy pll is used by other video port, report a error. If hdmi0 phy pll is used by another
 *    video port(B) and hdmi1 phy pll is free, set hdmi1 phy pll as video port(B) dclk parent and
 *    video port(A) hold hdmi0 phy pll. If hdmi0 phy pll is free, video port(A) hold hdmi0 pll.If
 *    video port(A) hold hdmi0 phy pll and request dclk is under 4k@60Hz, set hdmi0 phy pll as
 *    video port(A) dclk parent.
 *
 * 4. When a video port(A) connect hdmi1(may also connect other output interface but not hdmi0),
 *    it must hold the hdmi1 phy pll, and other video port can't use it. If both hdmi0 and hdmi1
 *    phy pll is used by other video port, report a error. If hdmi1 phy pll is used by another
 *    video port(B) and hdmi0 phy pll is free, set hdmi0 phy pll as video port(B) dclk parent and
 *    video port(A) hold hdmi1 phy pll. If hdmi1 phy pll is free, video port(A) hold hdmi1 pll. If
 *    video port(A) hold hdmi1 phy pll and request dclk is under 4k@60Hz, set hdmi1 phy pll as

 *
 * 5. When a video port connect dp(0, 1, or both, may also connect other output type but not hdmi0
 *    and hdmi1). If the request dclk is higher than 4K@60Hz or video port id is 2, do nothing.
