* [PATCH 3/3] arm64: dts: khadas-vim3: add support for the SM1 based VIM3
From: Neil Armstrong @ 2019-08-23  8:14 UTC (permalink / raw)
  To: khilman; +Cc: linux-amlogic, linux-kernel, linux-arm-kernel, Neil Armstrong
In-Reply-To: <20190823081427.17228-1-narmstrong@baylibre.com>

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