From 270bf3d4e53bf3cf22b7b2117053a96caf7dc407 Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Thu, 28 Mar 2019 23:49:22 -0700 Subject: [PATCH] ARM: dts: imx53: Specify IMX5_CLK_IPG as "ahb" clock to SDMA [ Upstream commit 28c168018e0902c67eb9c60d0fc4c8aa166c4efe ] Since 25aaa75df1e6 SDMA driver uses clock rates of "ipg" and "ahb" clock to determine if it needs to configure the IP block as operating at 1:1 or 1:2 clock ratio (ACR bit in SDMAARM_CONFIG). Specifying both clocks as IMX5_CLK_SDMA results in driver incorrectly thinking that ratio is 1:1 which results in broken SDMA funtionality. Fix the code to specify IMX5_CLK_AHB as "ahb" clock for SDMA, to avoid detecting incorrect clock ratio.
