[PATCH 1/2] arm64: dts: ti: k3-am65: disable optional peripherals by default

From: Matthias Schiffer
Date: Tue Jan 11 2022 - 06:26:05 EST

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.
