Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Kevin Hilman: "Some of these are for drivers/soc, where we're now putting SoC-specific drivers these days. Some are for other driver subsystems where we have received acks from the appropriate maintainers. Some highlights: - simple-mfd: document DT bindings and misc updates - migrate mach-berlin to simple-mfd for clock, pinctrl and reset - memory: support for Tegra132 SoC - memory: introduce tegra EMC driver for scaling memory frequency - misc. updates for ARM CCI and CCN busses" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (48 commits) drivers: soc: sunxi: Introduce SoC driver to map SRAMs arm-cci: Add aliases for PMU events arm-cci: Add CCI-500 PMU support arm-cci: Sanitise CCI400 PMU driver specific code arm-cci: Abstract handling for CCI events arm-cci: Abstract out the PMU counter details arm-cci: Cleanup PMU driver code arm-cci: Do not enable CCI-400 PMU by default firmware: qcom: scm: Add HDCP Support ARM: berlin: add an ADC node for the BG2Q ARM: berlin: remove useless chip and system ctrl compatibles clk: berlin: drop direct of_iomap of nodes reg property ARM: berlin: move BG2Q clock node ARM: berlin: move BG2CD clock node ARM: berlin: move BG2 clock node clk: berlin: prepare simple-mfd conversion pinctrl: berlin: drop SoC stub provided regmap ARM: berlin: move pinctrl to simple-mfd nodes pinctrl: berlin: prepare to use regmap provided by syscon reset: berlin: drop arch_initcall initialization ...
