Subject: [PATCH v2 1/2] dt-bindings: stm32: Add bindings for Extended TrustZone Protection
Date: Thu, 1 Mar 2018 14:58:05 +0100 [thread overview]
Message-ID: <20180301135806.19982-2-benjamin.gaignard@st.com> (raw)
In-Reply-To: <20180301135806.19982-1-benjamin.gaignard@st.com>
Extended TrustZone Protection driver is very basic and only needs
to know where are the registers (no clock, no interrupt)

+STMicroelectronics STM32 Extended TrustZone Protection driver
+
+Required properties:
+ - compatible : value should be "st,stm32mp1-etzpc"
+ - reg : physical base address of the IP registers and length of memory
+ mapped region.
+ - protected-devices: list of phandle of devices protected by etzpc.
+ Because etzpc driver rely on the phandle index in
+ the list, holes must be filled with a disabled node.
+
+Example for stm32mp1:
+
+reserved: disabled_node {
+ status = "disabled";
+};
+
+etzpc: etzpc@5c007000 {
+ compatible = "st,stm32mp1-etzpc";
+ reg = <0x5c007000 0x400>;
+ protected-devices = <&usart1>,
+ <&spi6>,
+ <&i2c4>,
+ <&reserved>,
+ <&rng1>;
+};
