So I assume that the muxing is installed by the bootloader, and the kernel expects that this muxing is already in place, so that mcu_uart0 can work? Is there a reason not to make the pinmuxing explicit by copying it to the kernel's k3-am654-base-board.dts? > I can send a v2 if this patch is acceptable at all (which would be > desirable for the addition of our TQMa65xx SoM and MBa65xx carrier > board, as it allows for a similar reduction of DTS lines as the one > seen in the diffstat below for k3-am65-iot2050-common.dtsi and > k3-am654-base-board.dts). > > Kind regards, > Matthias > > > > Signed-off-by: Matthias Schiffer > > > > --- > > > > These changes were not tested on hardware, and I'm not familiar > > with > > any of these boards, so it would be great if someone could check > > whether the effective changes listed above are correct, or if some > > of > > these devices (in particular I2C, UART and PWM) are actually > > connected > > and work with the default pinmuxing. > > > > There were also a few devices where I was unsure whether they are > > optional > > or not - for example one of the io2050 disables all the txpru > > nodes, > > so > > maybe it would make sense to disable these in the SoC DTSI as well? > > I > > left > > these nodes unchanged for now. > > > > .../dts/ti/k3-am65-iot2050-common-pg1.dtsi | 4 - > > .../dts/ti/k3-am65-iot2050-common-pg2.dtsi | 7 + > > .../boot/dts/ti/k3-am65-iot2050-common.dtsi | 132 +++++--------- > > -- > > -- > > arch/arm64/boot/dts/ti/k3-am65-main.dtsi | 52 +++++++ > > arch/arm64/boot/dts/ti/k3-am65-mcu.dtsi | 10 ++ > > arch/arm64/boot/dts/ti/k3-am65-wakeup.dtsi | 2 + > > .../ti/k3-am6528-iot2050-basic-common.dtsi | 6 +- > > .../arm64/boot/dts/ti/k3-am654-base-board.dts | 129 +++----------- > > -- > > - > > .../ti/k3-am6548-iot2050-advanced-common.dtsi | 5 +- > > 9 files changed, 134 insertions(+), 213 deletions(-) > > > > diff --git a/arch/arm64/boot/dts/ti/k3-am65-iot2050-common-pg1.dtsi > > b/arch/arm64/boot/dts/ti/k3-am65-iot2050-common-pg1.dtsi > > index 51f902fa35a7..746f0e89a305 100644 > > --- a/arch/arm64/boot/dts/ti/k3-am65-iot2050-common-pg1.dtsi > > +++ b/arch/arm64/boot/dts/ti/k3-am65-iot2050-common-pg1.dtsi > > @@ -13,10 +13,6 @@ &dss { > > assigned-clock-parents = <&k3_clks 67 5>;
