* arm64: dts: exynos7: add specific compatibles to several blocksKrzysztof Kozlowski2023-11-151-8/+10
| | | | | | | | | | | | | | | | | Exynos7 reuses several devices from older designs, thus historically we kept the old (block's) compatible only. This works fine and there is no bug here, however guidelines expressed in Documentation/devicetree/bindings/writing-bindings.rst state that: 1. Compatibles should be specific. 2. We should add new compatibles in case of bugs or features. Add compatibles specific to Exynos7 in front of all old-SoC-like compatibles. This will also help reviews of new code using existing DTS as template. No functional impact on Linux drivers behavior.

* ARM: dts: Move .dts files to vendor sub-directoriesRob Herring2023-06-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The arm dts directory has grown to 1559 boards which makes it a bit unwieldy to maintain and use. Past attempts stalled out due to plans to move .dts files out of the kernel tree. Doing that is no longer planned (any time soon at least), so let's go ahead and group .dts files by vendors. This move aligns arm with arm64 .dts file structure. There's no change to dtbs_install as the flat structure is maintained on install. The naming of vendor directories is roughly in this order of preference: - Matching original and current SoC vendor prefix/name (e.g. ti, qcom) - Current vendor prefix/name if still actively sold (SoCs which have been aquired) (e.g. nxp/imx) - Existing platform name for older platforms not sold/maintained by any company (e.g. gemini, nspire) The whole move was scripted with the exception of MAINTAINERS and a few makefile fixups.

| | | | | | | | | | | | | | | | | It's not possible to reboot or poweroff Exynos7420 using PSCI. Instead we need to use syscon reboot/poweroff drivers, like it's done for other Exynos SoCs.

To be able to use custom restart/poweroff handlers instead of PSCI functions, we need to correct psci compatible. This also requires us to provide function ids for CPU_ON and CPU_OFF.

| * arm64: dts: Fix broken architected timer interrupt triggerMarc Zyngier2016-09-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ARM architected timer specification mandates that the interrupt associated with each timer is level triggered (which corresponds to the "counter >= comparator" condition). A number of DTs are being remarkably creative, declaring the interrupt to be edge triggered. A quick look at the TRM for the corresponding ARM CPUs clearly shows that this is wrong, and I've corrected those. For non-ARM designs (and in the absence of a publicly available TRM), I've made them active low as well, which can't be completely wrong as the GIC cannot disinguish between level low and level high. The respective maintainers are of course welcome to prove me wrong. While I was at it, I took the liberty to fix a couple of related issue, such as some spurious affinity bits on ThunderX, and their complete absence on ls1043a (both of which seem to be related to copy-pasting from other DTs).
