Add support for the RaspberryPi Camera v2 which is an IMX219 8MP module: - https://datasheets.raspberrypi.com/camera/camera-v2-schematics.pdf - has its own on-board 24MHz osc so no clock required from baseboard - pin 11 enables 1.8V and 2.8V LDO which is connected to GW73xx MIPI_GPIO4 (IMX8MM GPIO1_IO1) so we use this as a gpio Support is added via a device-tree overlay. The IMX219 supports RAW8/RAW10 image formats. Signed-off-by: Tim Harvey <tharvey@xxxxxxxxxxxxx> --- v3: use overlay target for simplicity v2: - added DTC_FLAGS - add line between prop and subnode of mipi_csi/port@0 - add mipi_csi/port@1 to fix compile warning --- arch/arm64/boot/dts/freescale/Makefile | 2 + .../imx8mm-venice-gw72xx-0x-imx219.dts | 93 +++++++++++++++++++ 2 files changed, 95 insertions(+) create mode 100644 arch/arm64/boot/dts/freescale/imx8mm-venice-gw72xx-0x-imx219.dts diff --git a/arch/arm64/boot/dts/freescale/Makefile b/arch/arm64/boot/dts/freescale/Makefile index a84463bea15c..7f51b537df40 100644 --- a/arch/arm64/boot/dts/freescale/Makefile +++ b/arch/arm64/boot/dts/freescale/Makefile @@ -99,6 +99,7 @@ dtb-$(CONFIG_ARCH_MXC) += imx8qxp-colibri-eval-v3.dtb dtb-$(CONFIG_ARCH_MXC) += imx8qxp-mek.dtb dtb-$(CONFIG_ARCH_MXC) += imx8ulp-evk.dtb +imx8mm-venice-gw72xx-0x-imx219-dtbs := imx8mm-venice-gw73xx-0x.dtb imx8mm-venice-gw73xx-0x-imx219.dtbo imx8mm-venice-gw72xx-0x-rs232-rts-dtbs := imx8mm-venice-gw72xx-0x.dtb imx8mm-venice-gw72xx-0x-rs232-rts.dtbo imx8mm-venice-gw72xx-0x-rs422-dtbs := imx8mm-venice-gw72xx-0x.dtb imx8mm-venice-gw72xx-0x-rs422.dtbo imx8mm-venice-gw72xx-0x-rs485-dtbs := imx8mm-venice-gw72xx-0x.dtb imx8mm-venice-gw72xx-0x-rs485.dtbo @@ -107,6 +108,7 @@ imx8mm-venice-gw73xx-0x-rs232-rts-dtbs := imx8mm-venice-gw73xx-0x.dtb imx8mm-ven imx8mm-venice-gw73xx-0x-rs422-dtbs := imx8mm-venice-gw73xx-0x.dtb imx8mm-venice-gw73xx-0x-rs422.dtbo imx8mm-venice-gw73xx-0x-rs485-dtbs := imx8mm-venice-gw73xx-0x.dtb imx8mm-venice-gw73xx-0x-rs485.dtbo +dtb-$(CONFIG_ARCH_MXC) += imx8mm-venice-gw72xx-0x-imx219.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mm-venice-gw72xx-0x-rs232-rts.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mm-venice-gw72xx-0x-rs422.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mm-venice-gw72xx-0x-rs485.dtb diff --git a/arch/arm64/boot/dts/freescale/imx8mm-venice-gw72xx-0x-imx219.dts b/arch/arm64/boot/dts/freescale/imx8mm-venice-gw72xx-0x-imx219.dts new file mode 100644 index 000000000000..4eaf8aabcbff --- /dev/null +++ b/arch/arm64/boot/dts/freescale/imx8mm-venice-gw72xx-0x-imx219.dts @@ -0,0 +1,93 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright 2022 Gateworks Corporation + */ + +#include <dt-bindings/gpio/gpio.h> + +#include "imx8mm-pinfunc.h" + +/dts-v1/; +/plugin/; + +&{/} { + compatible = "gw,imx8mm-gw72xx-0x", "fsl,imx8mm"; + + reg_cam: regulator-cam { + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_reg_cam>; + compatible = "regulator-fixed"; + regulator-name = "reg_cam"; + gpio = <&gpio1 1 GPIO_ACTIVE_HIGH>; + enable-active-high; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + }; + + cam24m: cam24m { + compatible = "fixed-clock"; + #clock-cells = <0>; + clock-frequency = <24000000>; + clock-output-names = "cam24m"; + }; +}; + +&csi { + status = "okay"; +}; + +&i2c3 { + #address-cells = <1>; + #size-cells = <0>; + + imx219: sensor@10 { + compatible = "sony,imx219"; + reg = <0x10>; + clocks = <&cam24m>; + VDIG-supply = <®_cam>; + + port { + /* MIPI CSI-2 bus endpoint */ + imx219_to_mipi_csi2: endpoint { + remote-endpoint = <&imx8mm_mipi_csi_in>; + clock-lanes = <0>; + data-lanes = <1 2>; + link-frequencies = /bits/ 64 <456000000>; + }; + }; + }; +}; + +&mipi_csi { + status = "okay"; + + ports { + #address-cells = <1>; + #size-cells = <0>; + + port@0 { + reg = <0>; + + imx8mm_mipi_csi_in: endpoint { + remote-endpoint = <&imx219_to_mipi_csi2>; + data-lanes = <1 2>; + }; + }; + + port@1 { + reg = <1>; + + imx8mm_mipi_csi_out: endpoint { + remote-endpoint = <&csi_in>; + }; + }; + }; +}; + +&iomuxc { + pinctrl_reg_cam: regcamgrp { + fsl,pins = < + MX8MM_IOMUXC_GPIO1_IO01_GPIO1_IO1 0x41 + >; + }; +}; -- 2.17.1
