2023-06-21ARM: dts: Move .dts files to vendor sub-directoriesRob Herring1-432/+0
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.

2023-04-03ARM: dts: exynos: replace mshc0 alias with mmc-ddr-1_8v propertyHenrik Grimler1-0/+1
Previously, the mshc0 alias has been necessary so that MMC_CAP_1_8V_DDR | MMC_CAP_8_BIT_DATA are set for mshc_0/mmc_0. However, these capabilities should be described in the device tree so that we do not have to rely on the alias. The property mmc-ddr-1_8v replaces MMC_CAP_1_8V_DDR, while bus_width = <8>, which is already set for all the mshc0/mmc0 nodes, replaces MMC_CAP_8_BIT_DATA. Also drop other mshc aliases as they are not needed.

2020-12-29ARM: dts: exynos: correct PMIC interrupt trigger level on Artik 5Krzysztof Kozlowski1-1/+1
The Samsung PMIC datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU. Without specifying the interrupt type in Devicetree, kernel might apply some fixed configuration, not necessarily working for this hardware.

Commit 52005dece527 ("ARM: dts: Add assigned clock parents to CMU node for exynos3250") added assigned clocks under Clock Management Unit to fix hangs when accessing ISP registers.

2018-11-18ARM: dts: exynos: Add all CPUs in cooling mapsViresh Kumar1-2/+4
Each CPU can (and does) participate in cooling down the system but the DT only captures a handful of them, normally CPU0, in the cooling maps. Things work by chance currently as under normal circumstances its the first CPU of each cluster which is used by the operating systems to probe the cooling devices. But as soon as this CPU ordering changes and any other CPU is used to bring up the cooling device, we will start seeing failures. Also the DT is rather incomplete when we list only one CPU in the cooling maps, as the hardware doesn't have any such limitations. Update cooling maps to include all devices affected by individual trip points. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

These also applies to ARM and it will also allow to get rid of the following DTC warnings in the future: "Node /memory has a reg or ranges property, but no unit name" The disassembled DTB are almost the same besides an empty chosen node being removed and nodes reordered, so it should not have functional changes.
