Summary
add i3c tools
usage: i3c options...
options:
-b --bus bus to use.
-m --manufid manufacturer ID (upper 16 bits of PID).
-p --partid part ID (lower 32 bits of PID).
-r --read read data.
-w --write Write data block.
-g --get get a dev info.
-h --help Output usage message and exit.
Impact
debug toos for i3c
Testing
local compile test and run i3c tools
