Subject: [PATCH v1 RESEND] ARM64: dts: imx8mp: correct sdma1 clk setting
Date: Tue,  1 Sep 2020 18:21:49 +0800	[thread overview]
Message-ID: <1598955709-28688-1-git-send-email-yibin.gong@nxp.com> (raw)

Correct sdma1 ahb clk, otherwise wrong 1:1 clk ratio will be chosed so
that sdma1 function broken. sdma1 should use 1:2 clk, while sdma2/3 use
1:1.

Fixes: 6d9b8d20431f ("arm64: dts: freescale: Add i.MX8MP dtsi support")
