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: "This contains platform-related driver updates for ARM and ARM64. Highlights: - ARM SCMI (System Control & Management Interface) driver cleanups - Hisilicon support for LPC bus w/ ACPI - Reset driver updates for several platforms: Uniphier, - Rockchip power domain bindings and hardware descriptions for several SoCs. - Tegra memory controller reset improvements" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (59 commits) ARM: tegra: fix compile-testing PCI host driver soc: rockchip: power-domain: add power domain support for px30 dt-bindings: power: add binding for px30 power domains dt-bindings: power: add PX30 SoCs header for power-domain soc: rockchip: power-domain: add power domain support for rk3228 dt-bindings: power: add binding for rk3228 power domains dt-bindings: power: add RK3228 SoCs header for power-domain soc: rockchip: power-domain: add power domain support for rk3128 dt-bindings: power: add binding for rk3128 power domains dt-bindings: power: add RK3128 SoCs header for power-domain soc: rockchip: power-domain: add power domain support for rk3036 dt-bindings: power: add binding for rk3036 power domains dt-bindings: power: add RK3036 SoCs header for power-domain dt-bindings: memory: tegra: Remove Tegra114 SATA and AFI reset definitions memory: tegra: Remove Tegra114 SATA and AFI reset definitions memory: tegra: Register SMMU after MC driver became ready soc: mediatek: remove unneeded semicolon soc: mediatek: add a fixed wait for SRAM stable soc: mediatek: introduce a CAPS flag for scp_domain_data soc: mediatek: reuse regmap_read_poll_timeout helpers ...
