Hi Vaibhav,

In case of AM33xx family of devices (like cpsw) have different sysc
bit field offsets defined,
It is really used by several IPs, or it is just an unique exception?
For an exception, you can just define the omap_hwmod_sysc_fields for
that IP.
This is what SmartReflex is using for example.

sysc_type3:
| 3 2 | 1 0 |
| STDBYMODE | IDLEMODE |
So introduce new sysc_type3 in omap_hwmod common data.
