Subject: [PATCH] arm64: dts: fix node name for the sysclk
Date: Tue, 8 Jun 2021 14:26:58 +0300 [thread overview]
Message-ID: <20210608112658.4087235-1-olteanv@gmail.com> (raw)
From: Vladimir Oltean <vladimir.oltean@nxp.com>
U-Boot attempts to fix up the "clock-frequency" property of the "/sysclk" node:
https://elixir.bootlin.com/u-boot/v2021.04/source/arch/arm/cpu/armv8/fsl-layerscape/fdt.c#L512
but fails to do so:
## Booting kernel from Legacy Image at a1000000 ...
Image Name:
Created: 2021-06-08 10:31:38 UTC
Image Type: AArch64 Linux Kernel Image (gzip compressed)
Data Size: 15431370 Bytes = 14.7 MiB
Load Address: 80080000
Entry Point: 80080000
Verifying Checksum ... OK
## Flattened Device Tree blob at a0000000
Booting using the fdt blob at 0xa0000000
Uncompressing Kernel Image
Loading Device Tree to 00000000fbb19000, end 00000000fbb22717 ... OK
Unable to update property /sysclk:clock-frequency, err=FDT_ERR_NOTFOUND
Starting kernel ...
All Layerscape SoCs except LS1028A use "sysclk" as the node name, and
not "clock-sysclk". So change the node name of LS1028A accordingly.
Fixes: 8897f3255c9c ("arm64: dts: Add support for NXP LS1028A SoC")
