Looking at the TRM, "Table 13-43. DISPC_SYSCFG Register Field
Descriptions" seems to list the folowing bits available:

13-12	MIDLEMODE 
9-8	CLOCK_ACTIVITY 
4-3	SIDLEMODE 
2	ENWAKEUP 
1	SOFTRESET 
0	AUTOIDLE 

Have I missed something or how come we don't define them all
as available?

The .idlemodes available values and .sysc_fields seems to match
the TRM.

Regards,

Tony
