2022-01-24arm64: dts: ti: k3-j721s2: Move aliases to board dtsAswath Govindraju1-0/+10

2021-12-13arch: arm64: ti: Add support J721S2 Common Processor BoardAswath Govindraju1-0/+421
The EVM architecture for J721S2 is similar to that of J721E and J7200. It is as follows, +------------------------------------------------------+ | +-------------------------------------------+ | | | | | | | Add-on Card 1 Options | | | | | | | +-------------------------------------------+ | | | | | | +-------------------+ | | | | | | | SOM | | | +--------------+ | | | | | | | | | | | Add-on | +-------------------+ | | | Card 2 | | Power Supply | | Options | | | | | | | | | +--------------+ | <--- +------------------------------------------------------+ Common Processor Board Common Processor board is the baseboard that contains most of the actual connectors, power supply etc. The System on Module (SoM) is plugged on to the common processor baord. Therefore, add support for peripherals brought out in the common processor board.
