Subject: [PATCH v4 1/1] dt-bindings: fsl-qdma: allow compatible string fallback to fsl,ls1021a-qdma
Date: Wed, 10 Jul 2024 10:54:00 -0400 [thread overview]
Message-ID: <20240710145400.2257718-1-Frank.Li@nxp.com> (raw)
The IP of QDMA ls1028/ls1043/ls1046/ is same as ls1021. So allow compatible
string fallback to fsl,ls1021a-qdma.
The difference is that ls1021a-qdma have 3 irqs, and other have 5 irqs.
Fix below CHECK_DTB warning.
arch/arm64/boot/dts/freescale/fsl-ls1046a-rdb.dtb: dma-controller@8380000: compatible: ['fsl,ls1046a-qdma', 'fsl,ls1021a-qdma'] is too long
