This needs to be either mandatory or the default needs to be documented. I think it could be simply: Documentation/devicetree/bindings/media/video-interfaces.txt, valid values are 0 (sensor mounted upright; the default) and 180 (sensor mounted upside down). > + > +The device node shall contain one 'port' child node with an > +'endpoint' subnode for its digital output video port, > +in accordance with the video interface bindings defined in > +Documentation/devicetree/bindings/media/video-interfaces.txt. > + > +Example: > +&i2c4 { > + ov02a10: camera-sensor@3d { > + compatible = "ovti,ov02a10"; > + reg = <0x3d>; > + pinctrl-names = "default"; > + pinctrl-0 = <&camera_pins_cam1_mclk_on>; > + > + clocks = <&topckgen CLK_TOP_MUX_CAMTG2>, > + <&topckgen CLK_TOP_UNIVP_192M_D8>; > + clock-names = "eclk", "freq_mux"; > + clock-frequency = <24000000>; > + > + dovdd-supply = <&mt6358_vcamio_reg>; > + avdd-supply = <&mt6358_vcama1_reg>; > + dvdd-supply = <&mt6358_vcn18_reg>; > + powerdown-gpios = <&pio 107 GPIO_ACTIVE_LOW>; > + reset-gpios = <&pio 109 GPIO_ACTIVE_HIGH>; > + rotation = <180>; > + > + port { > + /* MIPI CSI-2 bus endpoint */ > + ov02a10_core: endpoint { > + remote-endpoint = <&ov02a10_0>; > + link-frequencies = /bits/ 64 <390000000>; > + }; > + }; > + }; > +}; > diff --git a/MAINTAINERS b/MAINTAINERS > index 783569e..41734fb 100644 > --- a/MAINTAINERS > +++ b/MAINTAINERS > @@ -11816,6 +11816,13 @@ T: git git://linuxtv.org/media_tree.git > S: Maintained > F: drivers/media/i2c/ov13858.c > > +OMNIVISION OV02A10 SENSOR DRIVER > +M: Dongchun Zhu > +L: linux-media@vger.kernel.org > +T: git git://linuxtv.org/media_tree.git > +S: Maintained > +F: Documentation/devicetree/bindings/media/i2c/ov02a10.txt > + > OMNIVISION OV2680 SENSOR DRIVER > M: Rui Miguel Silva > L: linux-media@vger.kernel.org -- Regards, Sakari Ailus sakari.ailus@linux.intel.com _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
