Robin Murphy authored
Commit 951d4885 ("of: Make of_dma_get_range() work on bus nodes") relaxed the handling of "dma-ranges" for any leaf node on the assumption that it would still represent a usage error for the property to be present on a non-bus leaf node. However there turns out to be a fiddly case where a bus also represents a DMA-capable device in its own right, such as a PCIe root complex with an integrated DMA engine on its platform side. In such cases, "dma-ranges" translation is entirely valid for devices discovered behind the bus, but should not be erroneously applied to the bus controller device itself which operates in its parent's address space. Fix this by restoring the previous behaviour for the specific case where a device is configured via its own OF node, since it is logical to assume that a device should never represent its own parent bus.

Add a make target, dt_compatible_check, to extract compatible strings from kernel sources and check if they are documented by a schema. At least version v2022.08 of dtschema with dt-check-compatible is required. This check can also be run manually on specific files or directories: scripts/dtc/dt-extract-compatibles drivers/clk/ | \ xargs dt-check-compatible -v -s Documentation/devicetree/bindings/processed-schema.json Currently, there are about 3800 undocumented compatible strings. Most of these are cases where the binding is not yet converted (given there are 1900 .txt binding files remaining).

It is useful to be able to recheck dtbs files against a limited set of DT schema files. This can be accomplished by using differnt DT_SCHEMA_FILES argument values while rerunning make dtbs_check. However for some reason if_changed_rule doesn't pick up the rule_dtc changes (and doesn't retrigger the build). Fix this by changing if_changed_rule to if_changed_dep and squashing DTC and dt-validate into a single new command. Then if_changed_dep triggers on DT_SCHEMA_FILES changes and reruns the build/check.

SoC MT7621 I2C bindings used text format, so migrate them to YAML. There are some additions to the binding that were not in the original txt file. This binding is used in MT7621 and MT7628a Ralink SoCs. To properly match both dts nodes in tree we need to add to the schema 'clocks', 'clock-names' and 'reset-names'. Both 'clock-names' and 'reset-names' use 'i2c' as string so maintain that as const in the schema. Also, Properly update MAINTAINERS file to align the changes. Signed-off-by:

Since the Armv7 and Armv8 architected timers are compatible, it is valid to expose a devicetree node with compatible string "arm,armv8-timer" followed by "arm,armv7-timer". For example a 32-bit guest running on a 64-bit machine may look for the v7 string even though the hardware is v8. VMMs such as QEMU and kvmtool have been using this compatible string for some time. Clean up the compatible list a little and add the dual option. Acked-by:

SMD edge contains subnodes representing devices related to the remote processor. With limietd number of remote processors, there is a limited set of such devices. List all of them in smd-edge bindings so schema can strictly check for subnodes. Additional benefit is requirement of "qcom,smd-channels" for such subnodes, because their schema cannot enforce it (few devices like APR or FastRPC can be part of either SMD or GLINK edge).

GLINK edge contains subnodes representing devices related to the remote processor. Each of such device (e.g. APR or FastRPC) must have a "qcom,glink-channels" property. However the APR or FastRPC device can be also part of other communication - SMD - thus their schema does not require "qcom,glink-channels".

If the properties 'linux,initrd-start' and 'linux,initrd-end' of the chosen node populated from the bootloader, eg. U-Boot, are so that start > end, then the phys_initrd_size calculated from end - start is negative that subsequently gets converted to a high positive value for being unsigned long long. Then, the memory region with the (invalid) size is added to the bootmem and attempted being paged in paging_init() that results in the kernel fault. For example, on the FVP ARM64 system I'm running, the U-Boot populates the 'linux,initrd-start' with 8800_0000 and 'linux,initrd-end' with 0. The phys_initrd_size calculated is then ffff_ffff_7800_0000 (= 0 - 8800_0000 = -8800_0000 + ULLONG_MAX + 1). paging_init() then attempts to map the address 8800_0000 + ffff_ffff_7800_0000 and oops'es as below. It should be stressed, it is generally a fault of the bootloader's with the kernel relying on it, however we should not allow the bootloader's misconfiguration to lead to the kernel oops. Not only the kernel should be bullet proof against it but also finding the root cause of the paging fault spanning over the bootloader, DT, and kernel may happen is not so easy.

In commit 853a78a7 (dt-bindings: leds: Add LED_COLOR_ID definitions, Sun Jun 9 20:19:04 2019 +0200) the most basic color definitions where added. However, there's a little more very common LED colors. While the documentation states 'add what is missing', engineers tend to be lazy and will just use what currently exists. So this patch will take (a) list from online retailers [0], [1], [2] and use the common LED colors from there, this being reasonable as this is what is currently available to purchase. Note, that LIME seems to be the modern take to 'Yellow-green' or 'Yellowish-green' from some older datasheets.

Convert Qualcomm FastRPC bindings to yaml format, so that we could validate dt-entries correctly and any future additions can go into yaml format. Use compute-cb@ subnodes instead of just cb@. Add qcom,glink-channels and qcom,smd-channels missing properties to make sure dtbs_check doesn't fail right off the bat. Correct the name of the parent node in the example from smd-edge to glink-edge. Since now the qcom,fastrpc bindings document is yaml, update the reference to it in qcom,glink-edge and also use $ref. Also update the MAINTAINERS file to point to the yaml version. Co-developed-by:
