Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC late DT updates from Arnd Bergmann: "These updates have been kept in a separate branch mostly because they rely on updates to the respective clk drivers to keep the shared header files in sync. This includes two branches for arm64 dt updates, both following up on earlier changes for the same platforms that are already merged: Samsung: - add USB3 support in Exynos7 - minor PM related updates Amlogic: - new machines: WeTek Set-top-boxes - various devices added to DT There are also a couple of bugfixes that trickled in since the start of the merge window: - The moxart_defconfig was not building the intended platform - CPU-hotplug was broken on ux500 - Coresight was broken on Juno (never worked)" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (26 commits) ARM: deconfig: fix the moxart defconfig ARM: ux500: resume the second core properly arm64: dts: juno: update definition for programmable replicator arm64: dts: exynos: Add regulators for Vbus and Vbus-Boost arm64: dts: exynos: Add USB 3.0 controller node for Exynos7 arm64: dts: exynos: Use macros for pinctrl configuration on Exynos7 pinctrl: dt-bindings: samsung: Add Exynos7 specific pinctrl macro definitions arm64: dts: exynos: Add initial configuration for DISP clocks for TM2/TM2e ARM64: dts: meson-gxbb-p200: add ADC laddered keys ARM64: dts: meson: meson-gx: add the SAR ADC ARM64: dts: meson-gxl: add the pwm_ao_b pin ARM64: dts: meson-gx: add the missing pwm_AO_ab node clk: gxbb: fix CLKID_ETH defined twice ARM64: dts: meson-gxl: rename Nexbox A95x for consistency clk: gxbb: add the SAR ADC clocks and expose them dt-bindings: amlogic: Add WeTek boards ARM64: dts: meson-gxbb: Add support for WeTek Hub and Play dt-bindings: vendor-prefix: Add wetek vendor prefix ARM64: dts: meson-gxm: Rename q200 and q201 DT files for consistency ARM64: dts: meson-gx: Add HDMI HPD/DDC pinctrl nodes ...
