* RPMH Master Stats
|
|
|
|
Differet Subsystems maintains master data in SMEM.
|
|
It tells about the individual masters information at any given
|
|
time like "system sleep counts", "system sleep last entered at"
|
|
and "system sleep accumulated duration" etc. These stats can be
|
|
displayed using the sysfs interface.
|
|
To achieve this, device tree node has been added.
|
|
|

|
|
