It seems my previous comments were not fully addressed. Maybe my feedback got lost between the quotes, maybe you just forgot to apply it. Please go back to the previous discussion and either implement all requested changes or keep discussing them. Thank you. 1. There is no driver, no DTS. You received the feedback about it. 2. Wrong cc list. You were asked to use get_maintainers.pl and still decide not to. > --- > .../devicetree/bindings/media/i2c/ov8858.yaml | 139 ++++++++++++++++++ > 1 file changed, 139 insertions(+) > create mode 100644 Documentation/devicetree/bindings/media/i2c/ov8858.yaml > > diff --git a/Documentation/devicetree/bindings/media/i2c/ov8858.yaml b/Documentation/devicetree/bindings/media/i2c/ov8858.yaml > new file mode 100644 > index 000000000000..f004e57b05ed > --- /dev/null > +++ b/Documentation/devicetree/bindings/media/i2c/ov8858.yaml > @@ -0,0 +1,139 @@ > +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/media/i2c/ov8858.yaml# Filename still does not match compatible. ovti,ov8858.yaml > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: Omnivision OV8856 CMOS Sensor Device Tree Bindings > + > +maintainers: > + - Nicholas Roth <nicholas@xxxxxxxxxxxxx> > + > +description: |- > + The Omnivision OV8858 is an 8 megapixel image sensor which provides > + images in RAW format over MIPI CSI-2 data bus with up to 4 lanes > + and is controlled through an I2C-compatibile SCCB bus. > + > +properties: > + compatible: > + const: ovti,ov8858 > + > + reg: > + maxItems: 1 > + > + clocks: > + maxItems: 1 > + > + clock-names: > + description: > + Input clock for the sensor. > + items: > + - const: xvclk > + > + clock-frequency: > + description: > + Frequency of the xvclk clock in Hertz. The frequency of clock should go via common clock framework - you have get_rate and set_rate.

If these are driver limitations, then drop it. Link frequencies are hardware related and you should here describe the minimum and maximum.
