Subject: [RFC,V2,03/11] dt-bindings: mt8183: Added camera ISP Pass 1
Date: Fri, 10 May 2019 09:57:52 +0800 [thread overview]
Message-ID: <20190510015755.51495-4-jungo.lin@mediatek.com> (raw)
In-Reply-To: <Jungo Lin <jungo.lin@mediatek.com>
This patch adds DT binding document for the Pass 1 (P1) unit in
Mediatek's camera ISP system. The Pass 1 unit grabs the sensor data
out from the sensor interface, applies ISP image effects from tuning
data and outputs the image data or statistics data to DRAM.

+* Mediatek Image Signal Processor Pass 1 (ISP P1)
+
+The Pass 1 unit of Mediatek's camera ISP system grabs the sensor data out
+from the sensor interface, applies ISP effects from tuning data and outputs
+the image data and statistics data to DRAM. Furthermore, Pass 1 unit has
+the ability to output two different resolutions frames at the same time to
+increase the performance of the camera application.
+
+Required properties:
+- compatible: Must be "mediatek,mt8183-camisp" for MT8183.
+- reg: Must contain an entry for each entry in reg-names.
+- interrupts: interrupt number to the cpu.
+- iommus: shall point to the respective IOMMU block with master port
+ as argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
+ for details.
+- power-domains : a phandle to the power domain of this local arbiter.
+- clocks: device clocks, see
+ Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
+- clock-names: must be "CAMSYS_CAM_CGPDN" and "CAMSYS_CAMTG_CGPDN".
+- 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 : the node of system control processor (SCP), see
+ Documentation/devicetree/bindings/remoteproc/mtk,scp.txt for details.
+- memory-region : the reserved shared memory region between Pass 1 unit and
+ system control processor.
+
+Example:
+SoC specific DT entry:
+
+ camisp: camisp@1a000000 {
+ compatible = "mediatek,mt8183-camisp", "syscon";
+ reg = <0 0x1a000000 0 0x1000>,
+ <0 0x1a003000 0 0x1000>,
+ <0 0x1a004000 0 0x2000>,
+ <0 0x1a006000 0 0x2000>;
+ reg-names = "camisp",
+ "cam1",
+ "cam2",
+ "cam3";
+ interrupts = <GIC_SPI 253 IRQ_TYPE_LEVEL_LOW>,
+ <GIC_SPI 254 IRQ_TYPE_LEVEL_LOW>,
+ <GIC_SPI 255 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-names = "cam1",
+ "cam2",
+ "cam3";
+ iommus = <&iommu M4U_PORT_CAM_LSCI0>,
+ <&iommu M4U_PORT_CAM_LSCI1>,
+ <&iommu M4U_PORT_CAM_BPCI>;
+ #clock-cells = <1>;
+ power-domains = <&scpsys MT8183_POWER_DOMAIN_CAM>;
+ /* Camera CCF */
+ clocks = <&camsys CLK_CAM_CAM>,
+ <&camsys CLK_CAM_CAMTG>;
+ clock-names = "CAMSYS_CAM_CGPDN",
+ "CAMSYS_CAMTG_CGPDN";
+ mediatek,larb = <&larb3>,
+ <&larb6>;
+ mediatek,scp = <&scp>;
+ memory-region = <&cam_mem_reserved>;
+ };
+
+Reserved memory specific DT entry (see reserved memory binding for more
+information):
+
+Example:
+SoC specific DT entry:
+
+ cam_mem_reserved: cam_mem_region {
+ compatible = "mediatek,reserve-memory-cam-smem";
+ no-map;
+ size = <0 0x01400000>; / *20 MB share mem size */
+ alignment = <0 0x1000>;
+ alloc-ranges = <0 0x40000000 0 0x10000000>;
+ };
+
+Mediatek ISP P1 supports a single port node with MIPI-CSI2 bus. It should
+contain one 'port' child node with child 'endpoint' node. Please refer to
+the bindings defined in Documentation/devicetree/bindings/media/video-interfaces.txt
+and Documentation/devicetree/bindings/media/mediatek-seninf.txt.
+
+Example:
+Board specific DT entry:
+
+ &camisp {
+ port@0 {
+ seninf_0: endpoint {
+ remote-endpoint = <&seninf_core>;
+ };
+ };
+ };
+
