[PATCH v1 0/3] riscv: dts: starfive: jh71x0: Add temperature sensor nodes and thermal-zones

[Hal Feng]

Hi, Conor,

These patches add temperature sensor nodes and thermal-zones for the
StarFive JH71X0 SoC. I have tested them on the BeagleV Starlight board
and StarFive VisionFive 1 / 2 board. Thanks.

Best regards,
Hal

Whatever about the other patches in this series, this one certainly
needs an Ack from Emil.

Hi @Emil,

Would you mind adding me as one of the maintainers of this driver?
Within StarFive, I was appointed to maintain this driver.

Best regards,
Hal
