Subject: ARM: dts: sun7i: Add Linutronix Testbox v2 board
X-Git-Tag: v5.10.7~2897^2~35^2~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c2bc78fe9d1c9aecc8a777221e3eb9d067987a8;p=platform%2Fkernel%2Flinux-rpi.git

ARM: dts: sun7i: Add Linutronix Testbox v2 board

The Testbox board is an open hardware enhancement for the Lamobo R1 router
board.  The Testbox board is used in the CI-RT project to manage devices
under test (https://ci-rt.linutronix.de).

The hardware project is located at https://github.com/ci-rt/testbox-shield

The Testbox v2 expands the Lamobo R1 router board with
- a power supply,
- a CAN bus PHY,
- a power control,
- a relay,
- an I2C EEPROM,
- a secure key storage (ATECC608a) and
- two RS232 compliant serial ports.
