20	depends on ARM_AMBA
21	help
22	  An implementation of the ARM PL320 Interprocessor Communication
23	  Mailbox (IPCM), tailored for the Calxeda Highbank. It is used to
24	  send short messages between Highbank's A9 cores and the EnergyCore
25	  Management Engine, primarily for cpufreq. Say Y here if you want
26	  to use the PL320 IPCM support.

32	  Mailbox implementation for OMAP family chips with hardware for
33	  interprocessor communication involving DSP, IVA1.0 and IVA2 in
34	  OMAP2/3; or IPU, IVA HD and DSP in OMAP4/5. Say Y here if you

49	help
50	  ACPI 5.0+ spec defines a generic mode of communication
51	  between the OS and a platform such as the BMC. This medium
52	  (PCC) is typically used by CPPC (ACPI CPU Performance management),
53	  RAS (ACPI reliability protocol) and MPST (ACPI Memory power
54	  states). Select this driver if your platform implements the
55	  PCC clients mentioned above.
