Hi Prabhakar, Thank you for the patch. On Fri, Mar 13, 2020 at 09:12:31PM +0000, Lad Prabhakar wrote: > Use assigned-clock-rates to specify the clock rate. Also mark > clock-frequency property as deprecated. I would phrase it the other way around, this patch mainly deprecates clock-frequency, and as a side effect recommends usage of assigned-clock-rates. "Deprecate usage of the clock-frequency propertly. The preferred method to set clock rates is to use assigned-clock-rates." > Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> > --- > Documentation/devicetree/bindings/media/i2c/ov5645.txt | 5 +++-- > 1 file changed, 3 insertions(+), 2 deletions(-) > > diff --git a/Documentation/devicetree/bindings/media/i2c/ov5645.txt b/Documentation/devicetree/bindings/media/i2c/ov5645.txt > index 72ad992..e62fe82 100644 > --- a/Documentation/devicetree/bindings/media/i2c/ov5645.txt > +++ b/Documentation/devicetree/bindings/media/i2c/ov5645.txt > @@ -8,7 +8,7 @@ Required Properties: > - compatible: Value should be "ovti,ov5645". > - clocks: Reference to the xclk clock. > - clock-names: Should be "xclk". > -- clock-frequency: Frequency of the xclk clock. > +- clock-frequency (deprecated): Frequency of the xclk clock. I would drop this completely. Drivers need to ensure backward compatibility, but DT bindings should only document the latest version, the history is available in git.
