Subject: [PATCH 1/5] arm64: dts: ti: k3-j7200: Add general purpose timers
Date:   Wed, 26 Apr 2023 16:02:15 +0530
Message-ID: <20230426103219.1565266-2-u-kumar1@ti.com>

There are 20 general purpose timers on j7200 that can be used for things
like PWM using pwm-omap-dmtimer driver. There are also additional ten
timers in the MCU domain.
