What: /sys/devices/platform/docg3/f[0-3]_dps[01]_is_keylocked
Date: November 2011
KernelVersion: 3.3
Contact: Robert Jarzmik <robert.jarzmik@free.fr>
Description:
Show whether the floor (0 to 4), protection area (0 or 1) is
keylocked. Each docg3 chip (or floor) has 2 protection areas,
which can cover any part of it, block aligned, called DPS.
The protection has information embedded whether it blocks reads,
writes or both.
The result is:
0 -> the DPS is not keylocked
1 -> the DPS is keylocked
Users: None identified so far.
