Mainly addressed to Greg but anyone is welcome to join the
discussion...

Several ARM platforms have system controllers. In this I
include all custom terminology such as:

- System Control
- Chip Controller
- Core Module control registers
- Power Reset Control Management Units
- Multimedia Communications Port

Why do you include this? ?If you include this, you should include things
like SSP/SPI ports, I2C and other such buses.

Mainly because it has these specific MCP controller oddity
functions:

mcp_set_telecom_divisor()
mcp_set_audio_divisor()

i.e. it has some "strangeness" of system controller type
(telecom? que?) But it's quite little and no big deal, drop
it off the list.

Thanks,
