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.
