From 9c015e13c875fccec2eeb903ab15266546b64b91 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Fri, 29 Nov 2019 22:09:37 +0100 Subject: [PATCH] arm64: dts: ls1028a: put SAIs into async mode The LS1028A SoC has only unidirectional SAIs. Therefore, it doesn't make sense to have the RX and TX part synchronous. Even worse, the RX part wont work out of the box because by default it is configured as synchronous to the TX part. And as said before, the pinmux of the SoC can only be configured to route either the RX or the TX signals to the SAI but never both at the same time. Thus configure the asynchronous mode by default.
