Nothing from this file is used and your commit msg does not provide rationale "why", thus it does not look like something for bindings. Otherwise please point me which patch with *driver* uses these bindings. > > Signed-off-by: Robert Marko <robert.marko@sartura.hr> > Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> > --- > include/dt-bindings/net/qcom-qca807x.h | 30 ++++++++++++++++++++++++++ Use filename matching compatible, so vendor,device.

Anyway these are raw values used to configure the qcom,control-dac property. In the driver it's used by qca807x_config_init. We read what is set in DT and we configure the reg accordingly. If this is wrong should we use a more schema friendly approach with declaring an enum of string and document that there? > > > > Signed-off-by: Robert Marko <robert.marko@sartura.hr> > > Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> > > --- > > include/dt-bindings/net/qcom-qca807x.h | 30 ++++++++++++++++++++++++++ > > Use filename matching compatible, so vendor,device.

Maybe I am missing something, but a quick scan of the patchset and a grep of the tree doesn't show this property being documented anywhere. > In the driver it's used by qca807x_config_init.

Without any idea of what that property is used for it is hard to say, but personally I much prefer enums of strings for what looks like a property that holds register values. That you felt it necessary to add defines for the values makes it more like that that is the case.

The big idea here was really to skip having to have a big function that parse strings but I get that it's better handle with string and have them documented directly in the yaml. > > > > > > > > > > Signed-off-by: Robert Marko <robert.marko@sartura.hr> > > > > Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> > > > > --- > > > > include/dt-bindings/net/qcom-qca807x.h | 30 ++++++++++++++++++++++++++ > > > > > > Use filename matching compatible, so vendor,device.
