Create initial schema for Microchip/SMSC LAN95xx USB Ethernet controllers and import some of currently supported USB IDs form drivers/net/usb/smsc95xx.c These devices are already used in some of DTs. So, this schema makes it official. NOTE: there was no previously documented txt based DT binding for this controllers. Signed-off-by:

When we boot a machine using a devicetree, the generic DT code goes through all nodes with a 'device_type = "memory"' property, and collects all memory banks mentioned there. However it does not check for the status property, so any nodes which are explicitly "disabled" will still be added as a memblock. This ends up badly for QEMU, when booting with secure firmware on arm/arm64 machines, because QEMU adds a node describing secure-only memory: =================== secram@e000000 { secure-status = "okay"; status = "disabled"; reg = <0x00 0xe000000 0x00 0x1000000>; device_type = "memory"; }; =================== The kernel will eventually use that memory block (which is located below the main DRAM bank), but accesses to that will be answered with an SError: =================== [ 0.000000] Internal error: synchronous external abort: 96000050 [#1] PREEMPT SMP [ 0.000000] Modules linked in: [ 0.000000] CPU: 0 PID: 0 Comm: swapper Not tainted 5.18.0-rc6-00014-g10c8acb8b679 #524 [ 0.000000] Hardware name: linux,dummy-virt (DT) [ 0.000000] pstate: 200000c5 (nzCv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 0.000000] pc : new_slab+0x190/0x340 [ 0.000000] lr : new_slab+0x184/0x340 [ 0.000000] sp : ffff80000a4b3d10 .... ================== The actual crash location and call stack will be somewhat random, and depend on the specific allocation of that physical memory range. As the DT spec[1] explicitly mentions standard properties, add a simple check to skip over disabled memory nodes, so that we only use memory that is meant for non-secure code to use. That fixes booting a QEMU arm64 VM with EL3 enabled ("secure=on"), when not using UEFI. In this case the QEMU generated DT will be handed on to the kernel, which will see the secram node. This issue is reproducible when using TF-A together with U-Boot as firmware, then booting with the "booti" command. When using U-Boot as an UEFI provider, the code there [2] explicitly filters for disabled nodes when generating the UEFI memory map, so we are safe. EDK/2 only reads the first bank of the first DT memory node [3] to learn about memory, so we got lucky there.

Convert the binding over to DT schema, to the DTs can be automatically checked.

The Arm SP810 IP is a "system controller", providing clocks, timer and a watchdog. Convert the DT binding to DT schema, to allow automatic validation. The existing .txt binding described all properties as required, but the assigned-clock* and clock-output-names are actually not (from a hardware perspective). The only existing driver I could find (in Linux) doesn't require them either, so drop those properties from the "required" list. Signed-off-by:

The Page Request Interface (PRI) is an optional PCIe feature. As such, a SMMU would not need to handle it if the PCIe host bridge or the SMMU itself do not implement it. Also an SMMU could be connected to a platform device, without any PRI functionality whatsoever. In all cases there would be no SMMU PRI queue interrupt to be wired up to an interrupt controller. At the moment, with the "eventq,gerror,priq,cmdq-sync" order, we would need to sacrifice the command queue sync interrupt as well, which might not be desired. Relax the binding to allow specifying certain useful combinations of wired interrupts, for instance just the "gerror" interrupt, or omitting both "pri" and "cmdq-sync". Signed-off-by:

Another round of removing redundant minItems/maxItems when 'items' list is specified. This time it is in if/then schemas as the meta-schema was failing to check this case. If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. Signed-off-by:

A few platforms, at91 and tegra, use drive-push-pull and drive-open-drain with a 0 or 1 value. There's not really a need for values as '1' should be equivalent to no value (it wasn't treated that way) and drive-push-pull disabled is equivalent to drive-open-drain. So dropping the value can't be done without breaking existing OSs. As we don't want new cases, mark the case with values as deprecated.

The values of enum of_overlay_notify_action are used to index into array of_overlay_action_name. Add an entry to of_overlay_action_name for the value recently added to of_overlay_notify_action. Array of_overlay_action_name[] is moved into include/linux/of.h adjacent to enum of_overlay_notify_action to make the connection between the two more obvious if either is modified in the future. The only use of of_overlay_action_name is for error reporting in overlay_notify(). All callers of overlay_notify() report the same error, but with fewer details. Remove the redundant error reports in the callers. Fixes: 067c0987 ("of: overlay: rework overlay apply and remove kfree()s") Reported-by:
