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 GW74xx MIPI_GPIO4 (IMX8MP GPIO1_IO4) so we use this as a gpio Support is added via a device-tree overlay. The IMX219 supports RAW8/RAW10 image formats. Example configuration: media-ctl -l "'imx219 3-0010':0->'csis-32e40000.csi':0[1]" media-ctl -v -V "'imx219 3-0010':0 [fmt:SRGGB8/640x480 field:none]" media-ctl -v -V "'crossbar':0 [fmt:SRGGB8/640x480 field:none]" media-ctl -v -V "'mxc_isi.0':0 [fmt:SRGGB8/640x480 field:none]" v4l2-ctl --set-fmt-video=width=640,height=480,pixelformat=RGGB v4l2-ctl --stream-mmap --stream-to=frame.raw --stream-count=1 convert -size 640x480 -depth 8 gray:frame.raw frame.png gst-launch-1.0 v4l2src ! \ video/x-bayer,format=rggb,width=640,height=480,framerate=10/1 ! \ bayer2rgb ! fbdevsink Signed-off-by: Tim Harvey <tharvey@xxxxxxxxxxxxx> --- arch/arm64/boot/dts/freescale/Makefile | 2 + .../imx8mp-venice-gw74xx-imx219.dtso | 80 +++++++++++++++++++ 2 files changed, 82 insertions(+) create mode 100644 arch/arm64/boot/dts/freescale/imx8mp-venice-gw74xx-imx219.dtso diff --git a/arch/arm64/boot/dts/freescale/Makefile b/arch/arm64/boot/dts/freescale/Makefile index 60a69e114442..9dc3c1be1899 100644 --- a/arch/arm64/boot/dts/freescale/Makefile +++ b/arch/arm64/boot/dts/freescale/Makefile @@ -156,6 +156,7 @@ imx8mm-venice-gw73xx-0x-rpidsi-dtbs := imx8mm-venice-gw73xx-0x.dtb imx8mm-venice imx8mm-venice-gw73xx-0x-rs232-rts-dtbs := imx8mm-venice-gw73xx-0x.dtb imx8mm-venice-gw73xx-0x-rs232-rts.dtbo 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 +imx8mp-venice-gw74xx-imx219-dtbs := imx8mp-venice-gw74xx.dtb imx8mp-venice-gw74xx-imx219.dtbo imx8mp-venice-gw74xx-rpidsi-dtbs := imx8mp-venice-gw74xx.dtb imx8mp-venice-gw74xx-rpidsi.dtbo dtb-$(CONFIG_ARCH_MXC) += imx8mm-venice-gw72xx-0x-imx219.dtb @@ -168,6 +169,7 @@ dtb-$(CONFIG_ARCH_MXC) += imx8mm-venice-gw73xx-0x-rpidsi.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mm-venice-gw73xx-0x-rs232-rts.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mm-venice-gw73xx-0x-rs422.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mm-venice-gw73xx-0x-rs485.dtb +dtb-$(CONFIG_ARCH_MXC) += imx8mp-venice-gw74xx-imx219.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mp-venice-gw74xx-rpidsi.dtb dtb-$(CONFIG_ARCH_S32) += s32g274a-evb.dtb diff --git a/arch/arm64/boot/dts/freescale/imx8mp-venice-gw74xx-imx219.dtso b/arch/arm64/boot/dts/freescale/imx8mp-venice-gw74xx-imx219.dtso new file mode 100644 index 000000000000..270a9114da97 --- /dev/null +++ b/arch/arm64/boot/dts/freescale/imx8mp-venice-gw74xx-imx219.dtso @@ -0,0 +1,80 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright 2023 Gateworks Corporation + */ + +#include <dt-bindings/gpio/gpio.h> + +#include "imx8mp-pinfunc.h" + +/dts-v1/; +/plugin/; + +&{/} { + compatible = "gw,imx8mp-gw74xx", "fsl,imx8mp"; + + reg_cam: regulator-cam { + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_reg_cam>; + compatible = "regulator-fixed"; + regulator-name = "reg_cam"; + gpio = <&gpio1 4 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"; + }; +}; + +&i2c4 { + #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 = <&mipi_csi_0_in>; + clock-lanes = <0>; + data-lanes = <1 2>; + link-frequencies = /bits/ 64 <456000000>; + }; + }; + }; +}; + +&isi_0 { + status = "okay"; +}; + +&mipi_csi_0 { + status = "okay"; + + ports { + port@0 { + mipi_csi_0_in: endpoint { + remote-endpoint = <&imx219_to_mipi_csi2>; + data-lanes = <1 2>; + }; + }; + }; +}; + +&iomuxc { + pinctrl_reg_cam: regcamgrp { + fsl,pins = < + MX8MP_IOMUXC_GPIO1_IO04__GPIO1_IO04 0x41 + >; + }; +}; -- 2.25.1
