From 986fa0721c1f1f5447ab3f8e36cc9d4ae17bce3f Mon Sep 17 00:00:00 2001 From: Fabrice Gasnier Date: Fri, 10 Jan 2025 10:19:22 +0100 Subject: [PATCH] arm64: dts: st: add timer nodes on stm32mp257f-ev1 Configure timer nodes on stm32mp257f-ev1: - Timer3 CH2 is available on mikroBUS connector for PWM - timer8 CH1, timer8 CH4, timer10 CH1 and timer12 CH2 are available on EXPANSION connector. Timers are kept disabled by default, so the pins can be used for any other purpose (and the timers can be assigned to any of the processors). Arbitrary choice is to use all these timers as PWM (or counter on internal clock signal), except for timer10 that is configured with CH1 as an input (for capture).
