Subject: [PATCH V3 RESEND 1/4] dt-bindings: fsl: scu: add ocotp binding
Date: Wed, 22 May 2019 01:46:54 +0000 [thread overview]
Message-ID: <20190522020040.30283-1-peng.fan@nxp.com> (raw)
NXP i.MX8QXP is an ARMv8 SoC with a Cortex-M4 core inside as
system controller(SCU), the ocotp controller is being controlled
by the SCU, so Linux need use RPC to SCU for ocotp handling. This
patch adds binding doc for i.MX8 SCU OCOTP driver.
