At the moment PinePhone comes in two slightly incompatible variants:

- 1.0: Early Developer Batch
- 1.1: Braveheart Batch

There will be at least one more incompatible variant in the very near
future, so let's start by sharing the dtsi among multiple variants,
right away, even though the HW description doesn't yet include the
different bits.

The differences between 1.0 and 1.1 are: change in pins that control
the flash LED, differences in modem power status signal routing, and
maybe some other subtler things, that have not been determined yet.

This is a basic DT that includes only features that are already
supported by mainline drivers.

This enables passive cooling by down-regulating CPU voltage
and frequency.

For the trip points, I used values from the BSP code directly.

The critical trip point value is 30°C above the maximum recommended
ambient temperature (70°C) for the SoC from the datasheet, so there's
some headroom even at such a high ambient temperature.

For trip points, I used a slightly lowered values from the BSP

like a lot, so I rounded it off to 100°C.

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.
