Subject: [PATCH v2] arm64: dts: ti: k3-{am62p,j722s}: Disable ethernet by default
Date: Wed,  3 Apr 2024 12:15:45 +0200	[thread overview]
Message-ID: <20240403101545.3932437-1-mwalle@kernel.org> (raw)

Device tree best practice is to disable any external interface in the
dtsi and just enable them if needed in the device tree. Thus, disable
the ethernet switch and its ports by default and just enable the ones
used by the EVMs in their device trees.

There is no functional change.

v2:
 - move the status propert into k3-am62p5-main.dtsi, thus also update
   the k3-am62p5-sk.dts
 - put "status" last
