Subject: [PATCH 2/3] dt-bindings: remoteproc: add Versal-NET platform
AMD-Xilinx Versal-NET platform is successor of Versal platform. It
contains multiple clusters of cortex-R52 real-time processing units.
Each cluster contains two cores of cortex-R52 processors. Each cluster
can be configured in lockstep mode or split mode.
Each R52 core is assigned 128KB of TCM memory. ATCM memory is 64KB, BTCM
and CTCM memoreis are 32KB each. Each TCM memory has its own dedicated
power-domain that needs to be requested before using it.
