Subject: [RESEND PATCH] arm64: dts: synaptics: remove unused DTSI for AS370
The as370.dtsi for Synaptics AS370 SoC does not have a user (DTS board
file), is uncompilable and untestable. It was added back in 2018. No
user appeared since that time, so assume it won't be added.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
Acked-by: Rob Herring <robh@...nel.org>
---
The AS370 board was submitted for review in Aug 2021 [1] but after few
comments there were no resubmits, so basically this is still a dead
DTSI.
