arm64: dts: amazon: alpine-v3: Add default GIC address cells

2025-09-04T13:50:30+00:00

Add missing address-cells 0 to GIC interrupt node to silence W=1 warning: alpine-v3.dtsi:342.4-349.33: Warning (interrupt_map): /soc/pcie@fbd00000:interrupt-map: Missing property '#address-cells' in node /soc/interrupt-controller@f0800000, using 0 as fallback Value '0' is correct because: 1. GIC interrupt controller does not have children, 2. interrupt-map property (in PCI node) consists of five components and the fourth component "parent unit address", which size is defined by '#address-cells' of the node pointed to by the interrupt-parent component, is not used (=0) Link: https://lore.kernel.org/r/20250822133423.312621-4-krzysztof.kozlowski@linaro.org Signed-off-by: Krzysztof Kozlowski

Merge tag 'dt64-cleanup-6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-dt into soc/dt

2024-04-29T16:12:53+00:00

Minor improvements in ARM64 DTS for v6.10 Fixes, which might have practical impact, however things were broken for long enough to justify pushing it regular path: 1. ARM Juno: shorten node names for thermal zones, because Linux drivers have strict limit of 20 characters. 2. HiSilicon: correct size of GIC GICC address space and add missing GICH and GICV spaces, add cache info to properly describe cache topology and solve kernel boot warning. Several cleanups: 1. Use capital "OR" for multiple licenses in SPDX. 2. Correct white-spaces for code readability. 3. Fix W=1 dtc compiler warnings, which should not have practical impact for Amazon, APM, Cavium, Realtek, Socionext Uniphier and Spreadtrum like: - missing unit addresses, - nodes not belonging to soc node, - not using generic node names, - few incorrect unit addresses. * tag 'dt64-cleanup-6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-dt: (28 commits) arm64: dts: cavium: thunder2-99xx: drop redundant reg-names arm64: dts: amazon: alpine-v3: correct gic unit addresses arm64: dts: amazon: alpine-v3: drop cache nodes unit addresses arm64: dts: amazon: alpine-v3: add missing io-fabric unit addresses arm64: dts: amazon: alpine-v2: move non-MMIO node out of soc arm64: dts: amazon: alpine-v2: add missing io-fabric unit addresses arm64: dts: apm: shadowcat: move non-MMIO node out of soc arm64: dts: apm: storm: move non-MMIO node out of soc arm64: dts: cavium: correct unit addresses arm64: dts: cavium: move non-MMIO node out of soc arm64: dts: realtek: rtc16xx: add missing unit address to soc node arm64: dts: realtek: rtd139x: add missing unit address to soc node arm64: dts: realtek: rtd129x: add missing unit address to soc node arm64: dts: uniphier: ld20-global: drop audio codec port unit address arm64: dts: uniphier: ld20-global: use generic node name for audio-codec arm64: dts: uniphier: ld11-global: drop audio codec port unit address arm64: dts: uniphier: ld11-global: use generic node name for audio-codec arm64: dts: sharkl3: add missing unit addresses arm64: dts: whale2: add missing ap-apb unit address arm64: dts: sc9860: move GIC to soc node ...

arm/arm64: dts: Drop "arm,armv8-pmuv3" compatible usage

2024-04-29T08:27:52+00:00

The "arm,armv8-pmuv3" compatible is intended only for s/w models. Primarily, it doesn't provide any detail on uarch specific events. There's still remaining cases for CPUs without any corresponding PMU definition and for big.LITTLE systems which only have a single PMU node (there should be one per core type).
