|
This driver gets reboot mode magic value from reboot-mode driver |
|
and stores it in a SYSCON mapped register. Then the bootloader |
|
can read it and take different action according to the magic |
|
value stored. The SYSCON mapped register is retrieved from the |
|
parental dt-node plus the offset. So the SYSCON reboot-mode node |
|
should be represented as a sub-node of a "syscon", "simple-mfd" node. |
