Add support for lan9662 OTP controller that is available on lan9662.
The driver gives access to non-volatile memory. It allows both write
and read access to it.
v3->v4:
- remove lan9668 compatible string from driver
- fix the bindings by changing the order of entries under items for
compatible property
v2->v3:
- fix dt-bindings, make sure that make dt_binding_check passes
- remove lan9662_writel/readl/clrbits/setbits and use writel/readl
- remove WARN_ON(offset >= OTP_MEM_SIZE) as it can't happen
v1->v2:
- remove unneed quotes for $ref: nvmem.yaml#
- rename lan966x to lan9662 as not to have any wildcards
- remove compatible string syscon
Horatiu Vultur (2):
dt-bindings: lan9662-otpc: document Lan9662 OTPC
