|
|
Description:
|
|
Expose the master that owns the bus (<bus-id>-<master-pid>) at
|
|
the time this file is read. Note that bus ownership can change
|
|
overtime, so there's no guarantee that when the read() call
|
|
returns, the value returned is still valid.

Description:
|
|
I3C bus mode. Can be "pure", "mixed-fast" or "mixed-slow". See
|
|
the I3C specification for a detailed description of what each
|
|
of these modes implies.

Description:
|
|
PID stands for Provisional ID and is used to uniquely identify
|
|
a device on a bus. This PID contains information about the
