Merge tag 'armsoc-platforms' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM/arm64 SoC platform updates from Olof Johansson: "This branch contains platform updates for 32- and 64-bit ARM, including defconfig updates to enable new options, drivers and platforms. There are also a few fixes and cleanups for some existing vendors. Some of the things worth highlighting here are: - Enabling new crypt drivers on arm64 defconfig - QCOM IPQ8074 clocks and pinctrl drivers on arm64 defconfig - Debug support enabled for Renesas r8a7743 - Various config updates for Renesas platforms (sound, USB, other drivers) - Platform support (including SMP) for TI dra762 - OMAP cleanups: Move to use generic 8250 debug_ll, removal of stale DMA code" * tag 'armsoc-platforms' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (109 commits) ARM: multi_v7_defconfig: make eSDHC driver built-in arm64: defconfig: enable rockchip graphics MAINTAINERS: Update Cavium ThunderX2 entry ARM: config: aspeed: Add I2C, VUART, LPC Snoop ARM: configs: aspeed: Update Aspeed G4 with VMSPLIT_2G ARM: s3c24xx: Fix NAND ECC mode for mini2440 board ARM: davinci_all_defconfig: enable tinydrm and ST7586 arm64: defconfig: Enable QCOM IPQ8074 clock and pinctrl ARM: defconfig: tegra: Enable ChipIdea UDC driver ARM: configs: Add Tegra I2S interfaces to multi_v7_defconfig ARM: tegra: Add Tegra I2S interfaces to defconfig ARM: tegra: Update default configuration for v4.13-rc1 MAINTAINERS: update ARM/ZTE entry soc: versatile: remove unnecessary static in realview_soc_probe() ARM: Convert to using %pOF instead of full_name ARM: hisi: Fix typo in comment ARM: multi_v7_defconfig: add CONFIG_BRCMSTB_THERMAL arm64: defconfig: add CONFIG_BRCMSTB_THERMAL arm64: defconfig: add recently added crypto drivers as modules arm64: defconfig: enable CONFIG_UNIPHIER_WATCHDOG ...
