2021-04-21of: overlay: Fix kerneldoc warning in of_overlay_remove()Rob Herring1-1/+1
'*ovcs_id' causes a warning because '*' is treated as bold markup: Documentation/devicetree/kernel-api:56: ../drivers/of/overlay.c:1184: WARNING: Inline emphasis start-string without end-string. Fix this by using the normal '@' markup for function parameters. That appears to be enough to keep the '*' from being interpretted as markup.

2021-04-21of/pci: Add IORESOURCE_MEM_64 to resource flags for 64-bit memory addressesLeonardo Bras1-1/+4
Many other resource flag parsers already add this flag when the input has bits 24 & 25 set, so update this one to do the same. Some devices (like virtio-net) have more than one memory resource (like MMIO32 and MMIO64) and without this flag it would be needed to verify the address range to know which one is which.

2021-04-16dt-bindings: bcm4329-fmac: add optional brcm,ccode-mapShawn Guo1-0/+8
Add optional brcm,ccode-map property to support translation from ISO3166 country code to brcmfmac firmware country code and revision. The country revision is needed because the RF parameters that provide regulatory compliance are tweaked per platform/customer. So depending on the RF path tight to the chip, certain country revision needs to be specified. As such they could be seen as device specific calibration data which is a good fit into device tree.

On some platforms, DDR parts are multi-sourced and the exact part number used is not know to either kernel or firmware at build time. Firmware can read identifying information from DDR mode registers at boot time but needs a way to communicate this information to kernel and/or userspace. This patch adds optional properties for this information to the existing "jedec,lpddr3" device tree binding to be used for that purpose.

2021-03-24dt-bindings: Convert the BCM4329 bindings to YAML and extendLinus Walleij2-38/+101
This converts the BCM4329 family bindings to YAML schema, and extends and fixes the bindings like this: - Name the bindings after the first chip (BCM4329) since wildcards like 43xx are nowadays frowned upon by the DT binding reviewers. We call this the "BCM4329 family" - Add compatible strings for all the variants that seem to exist in the wild. (Derived from firmware listings.) - Support specific-to-generic compatible strings (as already in use in DTS files). - Add required reg property (SDIO function number) - Add reset-gpios property (some systems wire this to a GPIO line). - I have only listed Arend as maintainer for now, volunteers can be added.

Adding checks for undocumented compatible strings reveals a bunch of warnings in the DT binding examples. Fix the cases which are typos, just a mismatch between the schema and the example, or aren't documented at all. In a couple of cases, fixing the compatible revealed some schema errors which are fixed. There's a bunch of others remaining after this which have bindings, but those aren't converted to schema yet.

2021-03-23of: unittest: Statically apply overlays using fdtoverlayViresh Kumar3-0/+56
Now that fdtoverlay is part of the kernel build, start using it to test the unitest overlays we have by applying them statically. Create two new base files static_base_1.dts and static_base_2.dts which includes other .dtsi files. Some unittest overlays deliberately contain errors that unittest checks for. These overlays will cause fdtoverlay to fail, and are thus not included for static builds.

2021-03-23of: unittest: Create overlay_common.dtsi and testcases_common.dtsiViresh Kumar5-106/+128
In order to build-test the same unit-test files using fdtoverlay tool, move the device nodes from the existing overlay_base.dts and testcases_common.dts files to .dtsi counterparts. The .dts files now include the new .dtsi files, resulting in exactly the same behavior as earlier. The .dtsi files can now be reused for compile time tests using fdtoverlay (will be done by a later commit). This is required because the base files passed to fdtoverlay tool shouldn't be overlays themselves (i.e. shouldn't have the /plugin/; tag). Note that this commit also moves "testcase-device2" node to testcases.dts from tests-interrupts.dtsi, as this node has a deliberate error in it and is only relevant for runtime testing done with unittest.c.

2021-03-16kbuild: Enable DT undocumented compatible checksRob Herring2-1/+5
dt-validate has an option to warn on any compatible strings which don't match any schema. The option has recently been improved to fix false positives, so let's enable the option. This is useful for tracking compatibles which are undocumented or not yet converted to DT schema. Previously, the only check of undocumented compatible strings has been an imperfect checkpatch.pl check. The option is enabled by default for 'dtbs_check'. This will add more warnings, but some platforms are down to only a handful of these warnings (good job!). There's about 100 cases in the binding examples, so the option is disabled until these are fixed. In the meantime, they can be checked with: make DT_CHECKER_FLAGS=-m dt_binding_check Cc: Maxime Ripard <mripard@kernel.org> Cc: Masahiro Yamada <masahiroy@kernel.org> Cc: Michal Marek <michal.lkml@markovi.net> Cc: linux-kbuild@vger.kernel.org Signed-off-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/20210311233640.1581526-2-robh@kernel.org

2021-03-11powerpc/kexec_file: Restore FDT size estimation for kdump kernelThiago Jung Bauermann3-20/+10
kexec_fdt_totalsize_ppc64() includes the base FDT size in its size calculation, but commit 3c985d31ad66 ("powerpc: Use common of_kexec_alloc_and_setup_fdt()") changed the kexec code to use the generic function of_kexec_alloc_and_setup_fdt() which already includes the base FDT size. That change made the code overestimate the size a bit by counting twice the space required for the kernel command line and /chosen properties. Therefore change kexec_fdt_totalsize_ppc64() to calculate just the extra space needed by the kdump kernel, and change the function name so that it better reflects what the function is now doing.
