Please, let's move forward by "downgrading" the Helped-by tags in this patch to Suggested-by tags, as you already suggested, to avoid possible delays with having this mount-matrix fix merged. We'll see what will happen with the proposed acceptance of the Helped-by tag, I haven't given up on that yet. :) > [*] > https://lore.kernel.org/linux-kernel/0e1ef28710e3e49222c966f07958a9879fa4e903.1729871544.git.dsimic@manjaro.org/T/#u > [**] > https://lore.kernel.org/linux-kernel/cover.1730874296.git.dsimic@manjaro.org/T/#u > >>> >> > --- >>> >> > >>> >> > Notes: >>> >> > See also the linux-sunxi thread [2] that has led to this patch, >>> >> > which >>> >> > provides a rather detailed analysis with additional details and >>> >> > pictures. >>> >> > This patch effectively replaces the patch submitted in that thread. >>> >> > >>> >> > [2] >>> >> > https://lore.kernel.org/linux-sunxi/20240916204521.2033218-1-andrej.skvortzov@gmail.com/T/#u >>> >> > >>> >> > arch/arm64/boot/dts/allwinner/sun50i-a64-pinephone.dtsi | 3 +++ >>> >> > 1 file changed, 3 insertions(+) >>> >> > >>> >> > diff --git a/arch/arm64/boot/dts/allwinner/sun50i-a64-pinephone.dtsi >>> >> > b/arch/arm64/boot/dts/allwinner/sun50i-a64-pinephone.dtsi >>> >> > index 6eab61a12cd8..b844759f52c0 100644 >>> >> > --- a/arch/arm64/boot/dts/allwinner/sun50i-a64-pinephone.dtsi >>> >> > +++ b/arch/arm64/boot/dts/allwinner/sun50i-a64-pinephone.dtsi >>> >> > @@ -212,6 +212,9 @@ accelerometer@68 { >>> >> > interrupts = <7 5 IRQ_TYPE_EDGE_RISING>; /* PH5 */ >>> >> > vdd-supply = <®_dldo1>; >>> >> > vddio-supply = <®_dldo1>; >>> >> > + mount-matrix = "0", "1", "0", >>> >> > + "-1", "0", "0", >>> >> > + "0", "0", "1"; >>> >> > }; >>> >> > }; >>> >>
