From 8efaff50f1a6dba74aa8a2a47dd5962fb098021b Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Tue, 27 Feb 2018 17:30:49 +0100 Subject: [PATCH] ARM: dts: imx7s: add spba-bus abstraction According to the i.MX 7Solo/Dual Application Processor Reference Manual the ECSPI1/2/3, UART1/2/3 and SAI1/2/3 peripherals are connected through the SPBA bus. Other similar SoCs such as i.MX 6UL add this bus abstraction. This adds the bus also to the i.MX 7 device tree. The i.MX SDMA driver uses this abstraction to configure watermark levels slightly differently, so this might change behavior slightly. There have no issues been observed before or after the patch.
