Subject: [RFC PATCH V3 1/5] dt-bindings: mt8183: Added DIP dt-bindings
Date: Tue, 10 Sep 2019 03:22:40 +0800 [thread overview]
Message-ID: <20190909192244.9367-2-frederic.chen@mediatek.com> (raw)
In-Reply-To: <20190909192244.9367-1-frederic.chen@mediatek.com>
From: Frederic Chen <frederic.chen@mediatek.com>
This patch adds DT binding documentation for the Digital Image
Processing (DIP) unit of camera ISP system on Mediatek's SoCs.
It depends on the SCP and MDP 3 patch as following:
1. dt-bindings: Add a binding for Mediatek SCP
https://patchwork.kernel.org/patch/11027247/
2. dt-binding: mt8183: Add Mediatek MDP3 dt-bindings
https://patchwork.kernel.org/patch/10945603/
Signed-off-by: Frederic Chen <frederic.chen@mediatek.com>

+* Mediatek Digital Image Processor (DIP)
+
+Digital Image Processor (DIP) unit in Mediatek ISP system is responsible for
+image content adjustment according to the tuning parameters. DIP can process
+the image form memory buffer and output the processed image to multiple output
+buffers. Furthermore, it can support demosaicing and noise reduction on the
+images.
+
+Required properties:
+- compatible: "mediatek,mt8183-dip"
+- reg: Physical base address and length of the function block register space
+- interrupts: interrupt number to the cpu
+- iommus: should point to the respective IOMMU block with master port as
+ argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
+ for details.
+- mediatek,mdp3: should point to the respective mdp block. DIP hardware
+ connects to MDP and we can get the processed image with both effect of the
+ two blocks.
+- mediatek,larb: must contain the local arbiters in the current SoCs, see
+ Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt
+ for details.
+- mediatek,scp: should point to the scp node since the we use SCP
+ coprocessor to control DIP hardware
+- clocks: must contain the local arbiters 5 (LARB5) and DIP clock
+- clock-names: must contain "larb5" and "dip"
+
+Example:
+ dip: dip@15022000 {
+ compatible = "mediatek,mt8183-dip";
+ mediatek,larb = <&larb5>;
+ mediatek,mdp3 = <&mdp_rdma0>;
+ mediatek,scp = <&scp>;
+ iommus = <&iommu M4U_PORT_CAM_IMGI>;
+ reg = <0 0x15022000 0 0x6000>;
+ interrupts = <GIC_SPI 268 IRQ_TYPE_LEVEL_LOW>;
+ clocks = <&imgsys CLK_IMG_LARB5>,
+ <&imgsys CLK_IMG_DIP>;
+ clock-names = "larb5",
+ "dip";
+ };
