2022-05-09dt-bindings: serio: add Arm PL050 DT schemaAndre Przywara1-0/+67
The Arm PL050 "Keyboard/Mouse Interface" is an Arm system IP providing a PS/2 compatible serial interface. Add a simple DT schema binding, based on the TRM[1], the existing DTs and the Linux driver.

The Arm PrimeCell Advanced Audio CODEC Interface (AACI aka PL041) is a peripheral that provides communication with an audio CODEC. Add a simple DT schema binding for it, so that DTs can be validated automatically.

2022-05-09dt-bindings: arm: sp810: convert to DT schemaAndre Przywara2-46/+80
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.

2022-05-09dt-bindings: iommu: arm,smmu-v3: make PRI IRQ optionalAndre Przywara1-5/+11
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".

2022-04-26dt-bindings: timer: Update TI timer to yamlTony Lindgren3-45/+143
Let's update the TI timer binding to use yaml. As this binding is specific to the TI dual-mode timers also known as dm-timers, let's use file name ti,timer-dm.yaml to avoid confusion with other timers. We add checks for the deprecated ti,hwmods property as done for other TI device driver bindings earlier. We also correct the issue with the old binding that was out of date for several properties. The am43 related timers are undocumented, but compatible with the am3 timers. Let's add the am43 timers too. The dm814 and dm816 timers are missing, let's add them. Some timers on some SoCs are dual mapped, like the ABE timers on omap4 and 5. The reg property maxItems must be updated to 2. The timer clocks can be managed by the parent interconnect target module with no clocks assigned for the timer node. And in some cases, the SoC may need to configure additional system clock for the timer in addition to the functional clock. The clock names are optional and not specific to the comptible property. For example, dra7 timers on l3 interconnect do not need clock-names, while the timers on dra7 l4 interconnect need them with both being compatible with ti,omap5430-timer.

2022-04-19of: of_property_read_string return -ENODATA when !lengthStefano Stabellini1-1/+4
When the length of the string is zero of_property_read_string should return -ENODATA according to the description of the function. However, of_property_read_string doesn't check prop->length. If prop->length is zero, return -ENODATA. Without this patch the following command in u-boot: fdt set /chosen/node property-name results in of_property_read_string returning -EILSEQ when attempting to read property-name. With this patch, it returns -ENODATA as expected.

2022-04-12of/irq: Use interrupts-extended to find parentSamuel Holland1-2/+11
The RISC-V PLIC binding uses interrupts-extended to specify its parent domain(s). That binding does not allow the interrupt-parent property to appear in the irqchip node. This prevents of_irq_init from properly detecting the irqchip hierarchy. If no interrupt-parent property is present in the enclosing bus or root node, then desc->interrupt_parent will be NULL for both the per-CPU RISC-V INTC (the actual root domain) and the RISC-V PLIC. Similarly, if the bus or root node specifies `interrupt-parent = <&plic>`, then of_irq_init will hit the `desc->interrupt_parent == np` check, and again all parents will be NULL. So things happen to work today for some boards due to Makefile ordering. However, things break when another irqchip ("foo") is stacked on top of the PLIC. The bus or root node will have `interrupt-parent = <&foo>`, since that is what all of the other peripherals need. When of_irq_init runs, it will try to find the PLIC's parent domain. of_irq_find_parent will fall back to using the interrupt-parent property of the PLIC's parent node (i.e. the bus or root node), and of_irq_init will see "foo" as the PLIC's parent domain. But this is wrong, because "foo" is actually the PLIC's child domain! So of_irq_init wrongly attempts to init the stacked irqchip before the PLIC. This fails and breaks booting. Fix this by using the first node referenced by interrupts-extended as the parent when that property is present. This allows of_irq_init to see the relationship between the PLIC and the per-CPU RISC-V INTC, and thus only the RISC-V INTC is (correctly) considered a root domain.
