Subject: [PATCH v1] arm64: dts: ti: k3-am64: Add ESM0 to device memory map
Date: Thu, 10 Feb 2022 11:22:46 -0600	[thread overview]
Message-ID: <20220210172246.27871-1-hnagalla@ti.com> (raw)

AM64x SoCs have two ESM modules, with one in MAIN voltage domain and the
other in MCU voltage domain. The error output from Main ESM module can
be routed to the MCU ESM module. The error output of MCU ESM can be
configured to reset the device. The MCU ESM configuration address space
is already opened and this patch opens the MAIN ESM configuration
address space.

For ESM details please refer technical reference manual at
