From dcac8eaaa90fe2c84761cf55a3e989ca5774d2f5 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Mon, 17 Oct 2022 14:25:27 -0500 Subject: arm64: dts: ti: k3-am64: Enable ECAP nodes at the board level ECAP nodes defined in the top-level AM64x SoC dtsi files are incomplete and will not be functional unless they are extended with pinmux information. (These and the EPWM nodes could be used to trigger internal actions but they are not used like that currently) As the pinmux is only known at the board integration level, these nodes should only be enabled when provided with this information. Disable the ECAP nodes in the dtsi files and only enable the ones that are actually pinned out on a given board.
