Subject: [PATCH] arm64: dts: ti: k3-j721s2-main: Add dts nodes for EHRPWMs
Date: Thu, 26 Jan 2023 18:52:43 +0530	[thread overview]
Message-ID: <20230126132243.15695-1-sinthu.raja@ti.com> (raw)

From: Sinthu Raja <sinthu.raja@ti.com>

Add dts nodes for 6 EHRPWM instances on SoC. Disable EHRPWM nodes in the
dtsi files and only enable the ones that are actually pinned out on a
given board.
