The DRA7xx family of SoCs usually have two IPU remote processor
subsystems. These subsystems are very similar to the respective
processor subsystems on OMAP4/OMAP5 in terms of clock and reset
integration. The relevant hwmod classes and data structures are
added for IPU1 and IPU2 remoteproc devices that's present on
almost all DRA7xx/AM57xx SoCs.
Do note that these hwmod data structures do not have a .modulemode
field as the devices are managed together with their corresponding
MMUs. Each of the processor subsystem and its MMU are present within
the same clock domain and requires the domain be clocked and enabled
until the last entity is disabled. The module is disabled properly
during the omap_device_idle processing of the MMU hwmod while
disabling the MMU.
