Subject: ARM: dts: lan966x: disable aes
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b716f7981e288e1367376903bc948bd9cf404440;p=linux.git

ARM: dts: lan966x: disable aes

Disable AES node on lan966x pcb8290, pcb891 and pcb8309 because these
boards have lan966x that uses secure OS which reserves the AES block.
Therefore it can't be exposed to non-secure world.
