i.mx6 Power Sequence

In my current project I want to use two parallel camera ports (CSI), powered with 1.8V on NVCC_CSI and NVCC_EIMx ports. The 1.8V supply and the camera ports come from a camera subsystem. When the i.mx6 processor is switched off, the camera system keeps the 1.8V supply and I/Os alive. This means that NVCC_CSI and NVCC_EIMx are still powered with 1.8V, while other i.mx6 power is turned off (except VDD_SNVS_IN). I didn't find anything in the datasheet, which is against this purpose. Anyway, I'm not shure if this is allowed.

 

Has anyone experiance with that ?

Are the NVCC supplies completely independend ?

 

Thanks and best regards
