Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "A bigger batch than I anticipated this week, for two reasons: - Some fallout on Davinci from board file -> DTB conversion, that also includes a few longer-standing fixes (i.e. not recent regressions). - drivers/reset material that has been in linux-next for a while, but didn't get sent to us until now for a variety of reasons (maintainer out sick, holidays, etc). There's a functional dependency in there such that one platform (Altera's SoCFPGA) won't boot without one of the patches; instead of reverting the patch that got merged, I looked at this set and decided it was small enough that I'll pick it up anyway. If you disagree I can revisit with a smaller set. That being said, there's also a handful of the usual stuff: - Fix for a crash on Armada 7K/8K when the kernel touches PSCI-reserved memory - Fix for PCIe reset on Macchiatobin (Armada 8K development board, what this email is sent from in fact :) - Enable a few new-merged modules for Amlogic in arm64 defconfig - Error path fixes on Integrator - Build fix for Renesas and Qualcomm - Initialization fix for Renesas RZ/G2E .. plus a few more fixlets" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (28 commits) ARM: integrator: impd1: use struct_size() in devm_kzalloc() qcom-scm: Include <linux/err.h> header gpio: pl061: handle failed allocations ARM: dts: kirkwood: Fix polarity of GPIO fan lines arm64: dts: marvell: mcbin: fix PCIe reset signal arm64: dts: marvell: armada-ap806: reserve PSCI area ARM: dts: da850-lcdk: Correct the sound card name ARM: dts: da850-lcdk: Correct the audio codec regulators ARM: dts: da850-evm: Correct the sound card name ARM: dts: da850-evm: Correct the audio codec regulators ARM: davinci: omapl138-hawk: fix label names in GPIO lookup entries ARM: davinci: dm644x-evm: fix label names in GPIO lookup entries ARM: davinci: dm355-evm: fix label names in GPIO lookup entries ARM: davinci: da850-evm: fix label names in GPIO lookup entries ARM: davinci: da830-evm: fix label names in GPIO lookup entries arm64: defconfig: enable modules for amlogic s400 sound card reset: uniphier-glue: Add AHCI reset control support in glue layer dt-bindings: reset: uniphier: Add AHCI core reset description reset: uniphier-usb3: Rename to reset-uniphier-glue dt-bindings: reset: uniphier: Replace the expression of USB3 with generic peripherals ...
