Subject: [PATCH] arm64: dts: ti: k3-am62-mcu: Add power-domains property for M4FSS
Date: Tue, 22 Sep 2026 22:49:42 +0530 [thread overview]
Message-ID: <20260922171942.201947-1-sid9.karanam@gmail.com> (raw)
Assign the power domain to the MCU M4FSS (Cortex-M4F) node by following
the device ids info published in TI-SCI public documentation.
This will be useful in future patches that will attempt at abstracting
ti_sci_dev_ops's calls such as get_device and put_device via pm_runtime
calls.
