Subject: [PATCH v2 0/2] eliminate two common errors reported by any yaml on arm64
Date: Fri, 16 Oct 2020 17:08:31 +0800 [thread overview]
Message-ID: <20201016090833.1892-1-thunder.leizhen@huawei.com> (raw)
v1 --> v2:
Although it's simpler to delete the empty "dma-ranges" property, and the function
of_translate_one() in drivers/of/address.c will treate non "dma-ranges" case as
empty "dma-ranges". But as Arnd Bergmann suggested: it's not good for the scenario
of IOMMU disabled or absented.
This version make sure that the node have empty "dma-ranges" property have the same
"#address-cells" and "#size-cells" values as its parent node.
v1:
The following errors occured no matter which YAML file I executed on arm64.
Therefore, it is necessary to eliminate it so that people's time and energy are
not wasted every time.
