2023-06-21ARM: dts: Move .dts files to vendor sub-directoriesRob Herring
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.

2019-07-01ARM: dts: exynos: Fix imprecise abort on Mali GPU probe on Exynos4210Marek Szyprowski
The PMU module of Mali400 GPU is optional and it looks that it is not present on Exynos4210, because any access to its registers causes external abort. This patch removes "pmu" interrupt for Exynos4210 SoCs, so the driver will skip the PMU module. This fixes following fault during kernel boot: Unhandled fault: imprecise external abort (0x1406) at 0x00000000 (lima_pmu_init) from [<c059e6f8>] (lima_device_init+0x244/0x5a0) (lima_device_init) from [<c059e40c>] (lima_pdev_probe+0x7c/0xd8) (lima_pdev_probe) from [<c05afcb8>] (platform_drv_probe+0x48/0x9c) (platform_drv_probe) from [<c05ad594>] (really_probe+0x1c4/0x400) (really_probe) from [<c05ad988>] (driver_probe_device+0x78/0x1b8) (driver_probe_device) from [<c05add30>] (device_driver_attach+0x58/0x60) (device_driver_attach) from [<c05ade34>] (__driver_attach+0xfc/0x160) (__driver_attach) from [<c05ab650>] (bus_for_each_dev+0x68/0xb4) (bus_for_each_dev) from [<c05ac734>] (bus_add_driver+0x104/0x20c) (bus_add_driver) from [<c05aece0>] (driver_register+0x78/0x10c) (driver_register) from [<c0103214>] (do_one_initcall+0x8c/0x430) (do_one_initcall) from [<c0f01328>] (kernel_init_freeable+0x3c8/0x4d0) (kernel_init_freeable) from [<c0ac3aa0>] (kernel_init+0x8/0x10c) (kernel_init) from [<c01010b4>] (ret_from_fork+0x14/0x20) The PMU module seems to work fine on Exynos4412 SoCs, so the patch also moves the interrupt definitions to exynos4210.dtsi and exynos4412.dtsi respectively, to keep only the common part in exynos4.dtsi.

2016-11-03ARM: dts: exynos: Fix invalid GIC interrupt flags in exynos4Krzysztof Kozlowski
Interrupt of type IRQ_TYPE_NONE is not allowed for GIC interrupts and generates an error: genirq: Setting trigger mode 0 for irq 16 failed (gic_set_type+0x0/0x68) The GIC requires shared interrupts to be edge rising or level high. Platform declares support for both. Arbitrarily choose level high everywhere hoping it will work on each platform.

2016-09-01ARM: dts: exynos: Remove skeleton.dtsi usage for Exynos4Javier Martinez Canillas
The skeleton.dtsi file was removed in ARM64 for different reasons as explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi"). 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.

2016-06-08ARM: dts: exynos: enable MFC device for all boardsMarek Szyprowski
MFC device can be used without any external hardware dependencies (when IOMMU is enabled), so it can be enabled by default (like it has been already done for Exynos 542x platforms). This unifies handling of this device for Exynos3250, Exynos4 and Exynos542x platforms. Board can still include exynos-mfc-reserved-memory.dtsi to enable using this device without IOMMU being enabled.

However, after these late comments, the driver expects different bindings so we need to fix the DTS. * tag 'samsung-dt-exynos-srom-fixup-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: ARM: dts: change SROM node compatible from generic to model specific
