Your commit does much more. You need to explain it why you drop some property. 2. Bindings go before its usage (in the patchset). 3. Please use scripts/get_maintainers.pl to get a list of necessary people and lists to CC. It might happen, that command when run on an older kernel, gives you outdated entries. Therefore please be sure you base your patches on recent Linux kernel. > > Signed-off-by: Dipen Patel > --- > v2: > - Removed nvidia,slices property > - Added nvidia,gpio-controller based on review comments from Thierry, > this will help simplify the hte provider driver. > > .../timestamp/nvidia,tegra194-hte.yaml | 30 ++++++++++++------- > 1 file changed, 19 insertions(+), 11 deletions(-) > > diff --git a/Documentation/devicetree/bindings/timestamp/nvidia,tegra194-hte.yaml b/Documentation/devicetree/bindings/timestamp/nvidia,tegra194-hte.yaml > index c31e207d1652..d0f4ed75baee 100644 > --- a/Documentation/devicetree/bindings/timestamp/nvidia,tegra194-hte.yaml > +++ b/Documentation/devicetree/bindings/timestamp/nvidia,tegra194-hte.yaml > @@ -4,7 +4,7 @@ > $id: http://devicetree.org/schemas/timestamp/nvidia,tegra194-hte.yaml# > $schema: http://devicetree.org/meta-schemas/core.yaml# > > -title: Tegra194 on chip generic hardware timestamping engine (HTE) > +title: Tegra on chip generic hardware timestamping engine (HTE) provider > > maintainers: > - Dipen Patel > @@ -23,6 +23,8 @@ properties: > enum: > - nvidia,tegra194-gte-aon > - nvidia,tegra194-gte-lic > + - nvidia,tegra234-gte-aon > + - nvidia,tegra234-gte-lic > > reg: > maxItems: 1 > @@ -38,14 +40,11 @@ properties: > minimum: 1 > maximum: 256 > > - nvidia,slices: > - $ref: /schemas/types.yaml#/definitions/uint32 > + nvidia,gpio-controller: > + $ref: /schemas/types.yaml#/definitions/phandle > description: > - HTE lines are arranged in 32 bit slice where each bit represents different > - line/signal that it can enable/configure for the timestamp.
