Subject: [PATCH v3 07/12] ARM: mstar: Add binding details for mstar,l3bridge
Date: Fri, 12 Jun 2020 22:00:07 +0900 [thread overview]
Message-ID: <20200612130032.3905240-8-daniel@0x0f.com> (raw)
In-Reply-To: <20200612130032.3905240-1-daniel@0x0f.com>
This adds a YAML description of the l3bridge node needed by the
platform code for the MStar/SigmaStar Armv7 SoCs.

+description: |
+ MStar/SigmaStar's Armv7 SoCs have a pipeline in the interface
+ between the CPU and memory. This means that before DMA capable
+ devices are allowed to run the pipeline must be flushed to ensure
+ everything is in memory.
+
+ The l3bridge region contains registers that allow such a flush
+ to be triggered.
+
+ This node is used by the platform code to find where the registers
+ are and install a barrier that triggers the required pipeline flush.
+
+properties:
+ compatible:
+ items:
+ - const: mstar,l3bridge
+
+ reg:
+ maxItems: 1
+
+required:
+ - compatible
+ - reg
+
+additionalProperties: false
+
+examples:
+ - |
+ l3bridge: l3bridge@1f204400 {
+ compatible = "mstar,l3bridge";
+ reg = <0x1f204400 0x200>;
+ };
