This should be reflected at list in the subject. Besides setting the drive strengths this patch also disables the pulls on some lines, so maybe better say something like "arm64: dts: qcom: sc7280: herobrine: Add pinconf settings for mi2s1". > Signed-off-by: Judy Hsiao > --- > arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi | 14 ++++++++++++++ > 1 file changed, 14 insertions(+) > > diff --git a/arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi b/arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi > index 9cb1bc8ed6b5..6d8744e130b0 100644 > --- a/arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi > +++ b/arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi > @@ -612,6 +612,20 @@ &dp_hot_plug_det { > bias-disable; > }; > > +&mi2s1_data0 { > + drive-strength = <6>; > + bias-disable; > +}; > + > +&mi2s1_sclk { > + drive-strength = <6>; > + bias-disable; > +}; > + > +&mi2s1_ws { > + drive-strength = <6>; > +}; > + > &pcie1_clkreq_n { > bias-pull-up; > drive-strength = <2>; > -- > 2.36.1.124.g0e6072fb45-goog > _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
