Clock ICG control manages the clock to each of the IPs using software control. For each module, there is a dedicated register <IP>_CLK_GATE part of MSS_RCM register space. By default all module clocks are enabled. Writing 0x7 into field GATED of corresponding <IP>_CLK_GATE will disable the clock to the IP.
Additionally, TOP_RCM host clock gating register R5SS0_CLK_GATE and R5SS1_CLK_GATE to disable core clock to individual R5SS. SYS_CLK_GATE disable SYS_CLK to the whole system. It is not recommended to gate R5SS_CLK and SYS_CLK as the system will hang and only option is to reset the whole system. TOP_RCM also allows clock gating for TRACE_CLK and CLKOUT0/CLKOUT1 ports.
