* arm64: dts: Add/fix /memory node unit-addressesRob Herring2024-05-021-1/+1
| | | | | | | | | | | | | | | | | | | '/memory' nodes always have a 'reg' property, and therefore should have a unit-address with just plain hex (i.e. no commas). Fix all the arm64 '/memory' nodes. It's possible that some bootloader depends on /memory (arm32 ATAG to DT code does for example). If so, the memory node should be commented with that requirement.

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 ...

| * arm64: dts: Fix various entry-method properties to reflect documentationAmit Kucheria2018-08-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idle-states binding documentation[1] mentions that the 'entry-method' property is required on 64-bit platforms and must be set to "psci". commit a13f18f59d26 ("Documentation: arm: Fix typo in the idle-states bindings examples") attempted to fix this earlier but clearly more is needed. Fix the cpu-capacity.txt documentation that uses the incorrect value so we don't get copy-paste errors like these. Clarify the language in idle-states.txt by removing the reference to the psci bindings that might be causing this confusion. Finally, fix devicetrees of various boards to reflect current documentation.
