This binding provides support for adjunct processors found on ST SoCs.
Co-processors can be controlled from the bootloader or the primary OS. If
the bootloader starts a co-processor, the primary OS must detect its state
and act accordingly.
Required properties:
- compatible Should be one of:
"st,st231-rproc"
"st,st40-rproc"
- memory-region Reserved memory (See: ../reserved-memory/reserved-memory.txt)
- resets Reset lines (See: ../reset/reset.txt)
- reset-names Must be "sw_reset" and "pwr_reset"
- clocks Clock for co-processor (See: ../clock/clock-bindings.txt)
- clock-frequency Clock frequency to set co-processor at if the bootloader
hasn't already done so
- st,syscfg System configuration register which holds the boot vector
for the co-processor
1st cell: Phandle to syscon block
2nd cell: Boot vector register offset
