This branch contains platform-related driver updates for ARM and ARM64, these are the areas that bring the changes: New drivers: - Driver support for Renesas R-Car V3M (R8A77970) - Power management support for Amlogic GX - A new driver for the Tegra BPMP thermal sensor - A new bus driver for Technologic Systems NBUS Changes for subsystems that prefer to merge through arm-soc: - The usual updates for reset controller drivers from Philipp Zabel, with five added drivers for SoCs in the arc, meson, socfpa, uniphier and mediatek families. - Updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla, Heiner Kallweit and Lorenzo Pieralisi. Changes specific to some ARM-based SoC - The Freescale/NXP DPAA QBMan drivers from PowerPC can now work on ARM as well. - Several changes for power management on Broadcom SoCs - Various improvements on Qualcomm, Broadcom, Amlogic, Atmel, Mediatek - Minor Cleanups for Samsung, TI OMAP SoCs -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJaDggbAAoJEGCrR//JCVInIeQQAN1MDyO1UaWiFYnbkVOgzFcj dqbFOc41DBE/90JoBWE8kR/rjyF83OqztiaYpx9viu2qMMBZVcOwxhCUthWK59c/ IujYdw4zGevLscF+jdrLbXgk97nfaWebsHyTAF307WAdZVJxiVGGzQEcgm71d6Zp CXjLiUii4winHUMK9FLRY2st0HKAevXhuvZJVV432+sTg3p7fGVilYeGOL5G62WO zQfCisqzC5q677kGGyUlPRGlHWMPkllsTTnfXcmV/FUiGyVa3lUWY5sEu+wCl96O U1ffPENeNj/A/4fa1dbErtbiNnC2z/+jf+Dg7Cn8w/dPk4Suf0ppjP8RqIGyxmDl Wm/UxbwDClxaeF4GSaYh2yKgGRJMH5N87bJnZRINE5ccGiol8Ww/34bFG0xNnfyh jSAFAc318AFG62WD4lvqWc7LSpzOYxp/MNqIFXKN692St/MJLkx8/q0nTwY1qPY0 3SELz9II3hz+3MfDRqtRi7hZpkgHgQ+UG7S5+Xhmqrl309GOEldCjPVJhhXxWoxK ZPtZOuyYvGhIC+YAnHaN6lUjADIdNJZHwbuXFImx85oKHVofoxHbcni5vk8Uu7z1 sQNYOtdDGaPG/2u9RJdJlPg/jIgLKxxt/Xm9TYVawpZ5hFANhBTtIq5ExCRAil68 j9sMOrpZ1DzCQyR7zN2v =qDhq -----END PGP SIGNATURE----- Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Arnd Bergmann: "This branch contains platform-related driver updates for ARM and ARM64, these are the areas that bring the changes: New drivers: - driver support for Renesas R-Car V3M (R8A77970) - power management support for Amlogic GX - a new driver for the Tegra BPMP thermal sensor - a new bus driver for Technologic Systems NBUS Changes for subsystems that prefer to merge through arm-soc: - the usual updates for reset controller drivers from Philipp Zabel, with five added drivers for SoCs in the arc, meson, socfpa, uniphier and mediatek families - updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla, Heiner Kallweit and Lorenzo Pieralisi Changes specific to some ARM-based SoC - the Freescale/NXP DPAA QBMan drivers from PowerPC can now work on ARM as well - several changes for power management on Broadcom SoCs - various improvements on Qualcomm, Broadcom, Amlogic, Atmel, Mediatek - minor Cleanups for Samsung, TI OMAP SoCs" [ NOTE! This doesn't work without the previous ARM SoC device-tree pull, because the R8A77970 driver is missing a header file that came from that pull. The fact that this got merged afterwards only fixes it at this point, and bisection of that driver will fail if/when you walk into the history of that driver. - Linus ] * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (96 commits) soc: amlogic: meson-gx-pwrc-vpu: fix power-off when powered by bootloader bus: add driver for the Technologic Systems NBUS memory: omap-gpmc: Remove deprecated gpmc_update_nand_reg() soc: qcom: remove unused label soc: amlogic: gx pm domain: add PM and OF dependencies drivers/firmware: psci_checker: Add missing destroy_timer_on_stack() dt-bindings: power: add amlogic meson power domain bindings soc: amlogic: add Meson GX VPU Domains driver soc: qcom: Remote filesystem memory driver dt-binding: soc: qcom: Add binding for rmtfs memory of: reserved_mem: Accessor for acquiring reserved_mem of/platform: Generalize /reserved-memory handling soc: mediatek: pwrap: fix fatal compiler error soc: mediatek: pwrap: fix compiler errors arm64: mediatek: cleanup message for platform selection soc: Allow test-building of MediaTek drivers soc: mediatek: place Kconfig for all SoC drivers under menu soc: mediatek: pwrap: add support for MT7622 SoC soc: mediatek: pwrap: add common way for setup CS timing extenstion soc: mediatek: pwrap: add MediaTek MT6380 as one slave of pwrap ..
