Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Olof Johansson: "Driver updates for ARM SoCs. Some for SoC-family code under drivers/soc, but also some other driver updates that don't belong anywhere else. We also bring in the drivers/reset code through arm-soc. Some of the larger updates: - Qualcomm support for SMEM, SMSM, SMP2P. All used to communicate with other parts of the chip/board on these platforms, all proprietary protocols that don't fit into other subsystems and live in drivers/soc for now. - System bus driver for UniPhier - Driver for the TI Wakeup M3 IPC device - Power management for Raspberry PI + Again a bunch of other smaller updates and patches" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (38 commits) bus: uniphier: allow only built-in driver ARM: bcm2835: clarify RASPBERRYPI_FIRMWARE dependency MAINTAINERS: Drop Kumar Gala from QCOM bus: uniphier-system-bus: add UniPhier System Bus driver ARM: bcm2835: add rpi power domain driver dt-bindings: add rpi power domain driver bindings ARM: bcm2835: Define two new packets from the latest firmware. drivers/soc: make mediatek/mtk-scpsys.c explicitly non-modular soc: mediatek: SCPSYS: Add regulator support MAINTAINERS: Change QCOM entries soc: qcom: smd-rpm: Add existing platform support memory/tegra: Add number of TLB lines for Tegra124 reset: hi6220: fix modular build soc: qcom: Introduce WCNSS_CTRL SMD client ARM: qcom: select ARM_CPU_SUSPEND for power management MAINTAINERS: Add rules for Qualcomm dts files soc: qcom: enable smsm/smp2p modular build serial: msm_serial: Make config tristate soc: qcom: smp2p: Qualcomm Shared Memory Point to Point soc: qcom: smsm: Add driver for Qualcomm SMSM ...
