U-Boot uses environment variables for storing device setup data. It usually needs to be accessed by a bootloader, kernel and often user-space. This binding allows describing environment data located in a raw flash partition. It's treated as NVMEM device and can be reused later for other storage devices. Using DT should be cleaner than hardcoding & duplicating such info in multiple places. Bootloader & kernel can share DTS and user-space can try reading it too or just have correct data exposed by a kernel. A custom "compatible" string allows system to automatically load relevant NVMEM driver but phandle can be also used for reading raw location. Signed-off-by:

'virtio,mmio' devices are always coherent within a guest. As Arm DTs are default non-coherent, the 'dma-coherent' property needs to be set on the virtio device to mark them as such. This aligns with the QEMU 'virt' machine DTB. Signed-off-by:

The CSR GSD4t is a CSR product using the SiRFstarIV core, and the CSR CSRG05TA03-ICJE-R is a CSR product using the SiRFstarV core. These chips have a SRESETN line that can be pulled low to hard reset the chip and in some designs this is connected to a GPIO, so add this as an optional property. Update the example with a reset line so users see that it need to be tagged as active low. Cc: devicetree@vger.kernel.org Cc: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by:

Switch the DT validation to use DTB files directly instead of a DTS to YAML conversion. The original motivation for supporting validation on DTB files was to enable running validation on a running system (e.g. 'dt-validate /sys/firmware/fdt') or other cases where the original source DTS is not available. The YAML format was not without issues. Using DTBs with the schema type information solves some of those problems. The YAML format relies on the DTS source level information including bracketing of properties, size directives, and phandle tags all of which are lost in a DTB file. While standardizing the bracketing is a good thing, it does cause a lot of extra warnings and churn to fix them. Another issue has been signed types are not validated correctly as sign information is not propagated to YAML. Using the schema type information allows for proper handling of signed types. YAML also can't represent the full range of 64-bit integers as numbers are stored as floats by most/all parsers. The DTB validation works by decoding property values using the type information in the schemas themselves. The main corner case this does not work for is matrix types where neither dimension is fixed. For now, checking the dimensions in these cases are skipped. Signed-off-by:

In preparation for supporting validation of DTB files, the full processed schema will always be needed in order to extract type information from it. Therefore, the processed schema containing only what DT_SCHEMA_FILES specifies won't work. Instead, dt-validate has gained an option, -l or --limit, to specify which schema(s) to use for validation. As the command line option is new, we the minimum dtschema version must be updated. Cc: Masahiro Yamada <masahiroy@kernel.org> Signed-off-by:
