Documentation/process/license-rules.rst and checkpatch expect the SPDX identifier syntax for multiple licenses to use capital "OR". Correct it to keep consistent format and avoid copy-paste issues. Correct also the format // -> .* in few Allwinner binding headers as pointed out by checkpatch: WARNING: Improper SPDX comment style for 'include/dt-bindings/reset/sun50i-h6-ccu.h', please use '/*' instead Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Acked-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Stephen Boyd <sboyd@kernel.org> Link: https://lore.kernel.org/r/20230823084540.112602-1-krzysztof.kozlowski@linaro.org Signed-off-by: Rob Herring <robh@kernel.org>

description:
|
|
The Xen IOMMU represents the Xen grant table interface. Grant mappings
|
|
are to be used with devices connected to the Xen IOMMU using the "iommus"
|
|
property, which also specifies the ID of the backend domain.
|
|
The binding is required to restrict memory access using Xen grant mappings.
