I want to confirm the specification of i.MX6 PLL in CCM module.
Actually, I want to use a external clock with spread spectrum via CLK1_N/CLK1_P pin to IPU, LDB as following route.
external clock -> CLK1_N, CLK1_P -> PLL5(CCM_ANALOG) -> CCM -> IPU, LDB
In this case, I think spread spectrum is preserve if I set PLL5 to bypass mode by BYPASS bit (CCM_ANALOG_PLL_VIDEOn in chapter18.7.11 of IMX6DQRM Rev.1).
Is this correct?
Or spread spectrum will be cancelled by PLL5 even if it is set to bypass mode?
