[PATCH v3 3/3] arm64: dts: khadas-vim3: add support for the SM1 based VIM3L

Neil Armstrong
2019-08-28T14:18:33Z

Add the Amlogic SM1 based Khadas VIM3L, sharing all the same features
as the G12B based VIM3, but:
- a different DVFS support since only a single cluster is available
- audio is still not available on SM1
