All peripharals that require pinmuxing or other configuration to work
should be disabled by default. Dependent DTS are adjusted accordingly.
The following nodes are now "disabled" according to dtx_diff and were not
overridden to "okay", as they define no pinctrl:
k3-am654-base-board:
- mcu_i2c0
- mcu_spi0..2
- cal
- main_i2c3
- ehrpwm0..5
- main_uart1..2
- main_spi1..4
k3-am65-iot2050*:
- mci_spi1..2
- cal
- ehrpwm0..5
- main_spi0..4

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.

I noticed that I didn't disable mcu_uart0 in k3-am65-mcu.dtsi, which
would make sense for consistency. It is currently not disabled in
k3-am654-base-board.dts either, but it doesn't have a pinmuxing
defined. Does it work with the default muxing, or should it rather be
disabled for that board?
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

Ah, I found a mcu_uart0 pinmuxing in ti-u-boot's k3-am654-r5-base-
board.dts. 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?

Thanks for testing. As noted earlier, I will send a v2 of this patch
that fixes one more inconsistency.

That seems to be an older issue, rather than a regression of this
patch:
k3-am65-main.dtsi defines:
ti,syscon-pcie-id = <&pcie_devid>;
ti,syscon-pcie-mode = <&pcie0_mode>
While according the driver binding docs something like the following is
expected:
ti,syscon-pcie-id = <&scm_conf 0x0210>;
ti,syscon-pcie-mode = <&scm_conf 0x4060>;
I assume that the k3-am65-main.dtsi section was imported from ti-linux
without accounting for the mainline driver's different binding.

Just rebased the still-too-long backlog to our system fully working over
mainline. Basically looks good, but this might be a regression of the
patch:
[ 1.810083] OF: /bus@100000/pcie@5600000: phandle pcie-mode@4070 needs 1, found 0
...
[ 1.854840] OF: /bus@100000/pcie@5600000: phandle pcie-devid@210 needs 1, found 0

Yep, 7dcf07ac88676a365ce3245b44af2be432f21120 caused it, and this seems
to be the fix (though I cannot find a negative impact yet, except for
