Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Olof Johansson: "Here are the main updates for SoC support (besides DT additions) for ARM 32- and 64-bit platforms. The branch also contains defconfig updates to turn on drivers and options as needed on the various platforms. The largest parts of the delta are from cleanups moving platform data and board file setup of TI platforms to ti-sysc bus drivers. There are also some sweeping changes of eeprom and nand setup on Davinci, i.MX and other platforms. Samsung is removing support for Exynos5440, which was an oddball SoC that hasn't been seen much use in designs. Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D). Linus Walleij is also removing support for ux500 (Sony Ericsson) U8540/9540 SoCs that never made it to significant mass production and products" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (133 commits) MAINTAINERS: add NXP linux team maillist as i.MX reviewer ARM: stm32: Don't select DMA unconditionally on STM32MP157C arm64: defconfig: Enable PCIe on msm8996 and db820c ARM: pxa3xx: enable external wakeup pins ARM: pxa: stargate2: use device properties for at24 eeprom arm64: defconfig: Enable HISILICON_LPC arm64: defconfig: enable drivers for Poplar support arm64: defconfig: Enable UFS on msm8996 ARM: berlin: switch to SPDX license identifier arm: berlin: remove non-necessary flush_cache_all() ARM: berlin: extend BG2CD Kconfig entry OMAP: CLK: CLKSRC: Add suspend resume hooks ARM: AM43XX: Add functions to save/restore am43xx control registers ASoC: ams_delta: use GPIO lookup table ARM: OMAP1: ams-delta: add GPIO lookup tables bus: ti-sysc: Fix optional clocks array access ARM: OMAP2+: Make sure LOGICRETSTATE bits are not cleared ARM: OMAP2+: prm44xx: Inroduce cpu_pm notifiers for context save/restore ARM: OMAP2+: prm44xx: Introduce context save/restore for am43 PRCM IO ARM: OMAP2+: powerdomain: Introduce cpu_pm notifiers for context save/restore ...
