43.5.2 Power Management
The ISC peripheral clock (hclock) is not continuously provided to the ISC. The programmer must first enable the ISC clock in the Power Management Controller (PMC) before using the ISC.
When the MIPI link is used to interface the ISC, refer to the sections "Camera Serial Interface (CSI)" to enable the MIPI PHY and "CSI-2 Demultiplexer Controller (CSI2DC)".
