[PATCH v1 15/16] RISC-V: Add initial StarFive JH7100 device tree

From: Emil Renner Berthing <kernel@esmil.dk>
Date: 2021-10-12 13:43:01
Also in: linux-clk, linux-gpio, linux-riscv, linux-serial, lkml
Subsystem: risc-v architecture, starfive devicetrees, the rest · Maintainers: Paul Walmsley, Palmer Dabbelt, Albert Ou, Emil Renner Berthing, Conor Dooley, Linus Torvalds

Add initial device tree for the StarFive JH7100 SoC.

The CPU and cache data is based on the device tree in the vendor u-boot
port.
