The Arm PL110 and PL111 are IP blocks that provide a display engine with an LCD interface, being able to drive a variety of LC panels. Convert the binding over to DT schema, to the DTs can be automatically checked. This still contains the deprecated "arm,pl11x,tft-r0g0b0-pads" property, because this is used by several DTs in the tree. Signed-off-by:

The Arm Versatile Express system features a bridge device that provides access to various smaller devices like clocks, reset gates and various sensors. Extract the second half of the informal vexpress-sysreg.txt binding and make it proper DT schema compliant. This makes the old .txt binding redundant, so remove it. This describes both the actual parent configuration bridge, as well as all the possible children devices. Signed-off-by:

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:

Convert the Arm Statisical Profiling Extension (SPE) binding to DT schema. Not much to see here, basically just the announcement that SPE is integrated on the system level and where the IRQ is routed to. Move it into the more suitable perf/ directory on the way. 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:

GENI(generic interface) based Qualcomm Universal Peripheral controller can support multiple serial interfaces like SPI,UART and I2C. Unlike other I2C controllers, QUP I2C bindings are present in parent schema. Move it out from parent to an individual binding and let parent refer to child schema later on. Please note, current schema isn't complete as it misses out few properties and thus, add these missing properties along the process. Signed-off-by:

New unittests for overlay notifiers reveal a memory leak in of_overlay_apply() when a notifier returns an error for action OF_OVERLAY_POST_APPLY.

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:

Convert the fsl,ls-extirq binding to the new YAML format. In contrast to the original binding documentation, there are three compatibles which are used in their corresponding device trees which have a specific compatible and the (already documented) fallback compatible: - "fsl,ls1046a-extirq", "fsl,ls1043a-extirq" - "fsl,ls2080a-extirq", "fsl,ls1088a-extirq" - "fsl,lx2160a-extirq", "fsl,ls1088a-extirq" Depending on the number of the number of the external IRQs which is usually 12 except for the LS1021A where there are only 6, the interrupt-map-mask was reduced from 0xffffffff to 0xf and 0x7 respectively and the number of interrupt-map entries have to match.

Convert infracfg bindings to DT schema format. Not all drivers currently implement resets, so #reset-cells is made a required property only for those that do. Using power-controller in the example node name makes #power-domain-cells required causing a dt_binding_check error. To solve this, the node is renamed to syscon@10001000. Signed-off-by:

Let's add compatible for ti,am654-timer for TI am64, am65 and j72 SoCs. As the timer hardware is the same between am64, am65 and j72 we use the compatible name for the earliest SoC with this timer. The timer interrupts are not routable for the operating system for some timers on am6. Let's make sure the interrupts are configured for the timers on all other SoCs.

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.
