[PATCH v1 8/9] riscv: dts: spacemit: add Banana Pi BPI-F3 board device tree
Posted by Yangyu Chen 1 year, 6 months ago 
Banana Pi BPI-F3 [1] is a industrial grade RISC-V development board, it
design with SpacemiT K1 8 core RISC-V chip [2].

Currently only support booting into console with only uart enabled,
other features will be added soon later.

Can we have "k1" prefix at least? so k1-bananapi-f3.dtb
it's much clear to let people know the board has k1 SoC,
in case vendor has more chip series..

Sounds like a good idea. I searched other references to "Banana Pi"
in Kernel dts and found they have the prefix of soc name.
