> This patch fixes the DP audio and video PLL configurations for the
> zynqmp-zcu102-revA evaluation board.
>
> The Linux DP driver expects the DP to be using the following PLL config:
>   - DP video PLL should use the VPLL (0x0)
>   - DP audio PLL should use the RPLL (0x3)
>
> Register 0xFD1A0070 configures the DP video PLL.
> Register 0xFD1A0074 configures the DP audio PLL.
