embedded real time clock running.

The DSP power domain is surrounded by an isolation wrapper to provide

proper electrical isolation and the appropriate interface state at the boundary

of the MPU and DSP power domains.

The assumption for OMAP5912 is that the power domains are connected

exclusively to external power supplies (not necessarily dedicated). No e-LDO

and no power switch are implemented in OMAP5912 to supply the MPU and

DSP domains.

When the DSP is in isolation mode, it is possible to cut its dedicated power

POWER_CTRL_REG in the ULPD register file. Table 51 describes the

isolation control bit.
