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

|
* If we found a VP is in standby mode when we want power down a PD is
|
* attached to it, we release the VP from standby mode, than it will

* 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
|
* video port(A) dclk parent.
|
*
|
* 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.
