* ARM: dts: exynos: replace mshc0 alias with mmc-ddr-1_8v propertyHenrik Grimler2023-04-031-3/+0
| | | | | | | | | | | | | | | | | | 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.

* ARM: dts: exynos: Remove skeleton.dtsi usage for Exynos3Javier Martinez Canillas2016-09-011-1/+2
| | | | | | | | | | | | | | | | | 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.

* ARM: dts: exynos: enable MFC device for all boardsMarek Szyprowski2016-06-081-1/+0
| | | | | | | | | | | | | 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.

The Renesas R-Car power domain handling, and the Nvidia Tegra USB support both hand notable changes that required changing the DT binding in a way that only provides compatibility with old DT blobs on new kernels but not vice versa. As a consequence, the DT changes are based on top of the driver changes and are now in this branch. For NXP i.MX and Samsung Exynos, the changes in here depend on other changes that got merged through the clk maintainer tree" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (35 commits) ARM: dts: exynos: Add support of Bus frequency using VDD_INT for exynos5422-odroidxu3 ARM: dts: exynos: Add bus nodes using VDD_INT for Exynos542x SoC ARM: dts: exynos: Add NoC Probe dt node for Exynos542x SoC ARM: dts: exynos: Add support of bus frequency for exynos4412-trats/odroidu3 ARM: dts: exynos: Expand the voltage range of buck1/3 regulator for exynos4412-odroidu3 ARM: dts: exynos: Add support of bus frequency using VDD_INT for exynos3250-rinato ARM: dts: exynos: Add exynos4412-ppmu-common dtsi to delete duplicate PPMU nodes ARM: dts: exynos: Add bus nodes using VDD_MIF for Exynos4210 ARM: dts: exynos: Add bus nodes using VDD_INT for Exynos4x12 ARM: dts: exynos: Add bus nodes using VDD_MIF for Exynos4x12 ARM: dts: exynos: Add bus nodes using VDD_INT for Exynos3250 ARM: dts: exynos: Add DMC bus frequency for exynos3250-rinato/monk ARM: dts: exynos: Add DMC bus node for Exynos3250 ARM: tegra: Enable XUSB on Nyan ARM: tegra: Enable XUSB on Jetson TK1 ARM: tegra: Enable XUSB on Venice2 ARM: tegra: Add Tegra124 XUSB controller ARM: tegra: Move Tegra124 to the new XUSB pad controller binding ARM: dts: r8a7794: Use SYSC "always-on" PM Domain ARM: dts: r8a7793: Use SYSC "always-on" PM Domain ...
