dt-bindings: Drop redundant minItems/maxItems

2021-06-21T19:56:46Z

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. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.

dt-bindings: timer: arm,arch_timer: Add interrupt-names support

2021-04-08T11:18:38Z

Not all platforms provide the same set of timers/interrupts, and Linux only needs one (plus kvm/guest ones); some platforms are working around this by using dummy fake interrupts. Implementing interrupt-names allows the devicetree to specify an arbitrary set of available interrupts, so the timer code can pick the right one. This also adds the hyp-virt timer/interrupt, which was previously not expressed in the fixed 4-interrupt form.

dt-bindings: timer: Document allwinner,erratum-unknown1 property

2020-05-11T22:28:02Z

This arch_timer property was added in commit c950ca8c35ee ("clocksource/drivers/arch_timer: Workaround for Allwinner A64 timer instability") but I omitted the device tree binding documentation. Now `make dtbs_check` prints the following warning for all A64 boards: timer: 'allwinner,erratum-unknown1' does not match any of the regexes: 'pinctrl-[0-9]+' Resolve this by documenting the erratum property.

dt-bindings: Clean-up schema indentation formatting

2020-04-16T21:59:22Z

Fix various inconsistencies in schema indentation. Most of these are list indentation which should be 2 spaces more than the start of the enclosing keyword. This doesn't matter functionally, but affects running scripts which do transforms on the schema files.

dt-bindings: Add missing 'additionalProperties: false'

2020-03-31T15:03:17Z

Setting 'additionalProperties: false' is frequently omitted, but is important in order to check that there aren't extra undocumented properties in a binding. Ideally, we'd just add this automatically and make this the default, but there's some cases where it doesn't work. For example, if a common schema is referenced, then properties in the common schema aren't part of what's considered for 'additionalProperties'. Also, sometimes there are bus specific properties such as 'spi-max-frequency' that go into bus child nodes, but aren't defined in the child node's schema. So let's stick with the json-schema defined default and add 'additionalProperties: false' where needed. This will be a continual review comment and game of wack-a-mole.
