From cc839d0f8c284fcb7591780b568f13415bbb737c Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Thu, 28 Mar 2019 23:49:21 -0700 Subject: [PATCH] ARM: dts: imx6sx: Specify IMX6SX_CLK_IPG as "ahb" clock to SDMA 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 IMX6SL_CLK_SDMA results in driver incorrectly thinking that ratio is 1:1 which results in broken SDMA funtionality. Fix the code to specify IMX6SL_CLK_AHB as "ahb" clock for SDMA, to avoid detecting incorrect clock ratio.
