Subject: [PATCH 1/2] arm64: dts: ti: k3-am62-main: Add epwm nodes
Date: Tue, 31 May 2022 23:52:28 +0300 [thread overview]
Message-ID: <20220531205229.198011-2-g-vlaev@ti.com> (raw)
In-Reply-To: <20220531205229.198011-1-g-vlaev@ti.com>
Add the compatible DT nodes for all EPWM instances
present in AM62 SoC. There is a total of 3 EPWM modules
available, sharing the same K3 IP as in AM64 SoC.
This also adds a required "ti,am62-epwm-tbclk" clock
provider node for the EPWM time-base clock.
Signed-off-by: Georgi Vlaev <g-vlaev@ti.com>
