From: Etienne Carriere <etienne.carriere@xxxxxx> Introduce boolean property st,non-secure-otp for OTP data located in a factory programmed area that only secure firmware can access by default and that shall be reachable from the non-secure world. This change also allows additional properties for NVMEM nodes that were forbidden prior this change. Signed-off-by: Etienne Carriere <etienne.carriere@xxxxxx> --- Changes since v1: Change nvmem.yaml to allow additional properties in NVMEM nodes.
