Subject: [PATCH] arm64: dts: imx8mm: Fix boot hang at clk init
Date: Thu, 25 Jul 2019 12:50:53 +0300	[thread overview]
Message-ID: <718c781b77081d6974fd91d5dff7b0f8737757b0.1564048197.git.leonard.crestez@nxp.com> (raw)

The assigned-clock-rates property is incorrect (4 elements while
assigned-clocks has length 5) and boot hangs while assigning some
unexpected rates.

Fix by inserting another <400000000>, the intention is to assign both
IMX8MM_CLK_AUDIO_AHB and IMX8MM_CLK_IPG_AUDIO_ROOT 400mhz.

Fixes: df1703896a17 ("arm64: dts: imx8mm: Init rates and parents configs for clocks")

Signed-off-by: Leonard Crestez <leonard.crestez@nxp.com>

Changes since v1:
* Insert and 400mhz instead of <0>
Link to v1: https://patchwork.kernel.org/patch/11057515/

Should probably be squashed into df1703896a17
