Re: [PATCH 4.19 080/118] ARM: dts: imx51: Specify IMX5_CLK_IPG as "ahb" clock to SDMA

Hi!

[ Upstream commit 918bbde8085ae147a43dcb491953e0dd8f3e9d6a ]

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.

I don't see 25aaa75df1e6 commit in stable-4.19.y branch. Is that intentional?

Best regards, Pavel
