Merge tag 'arm-newsoc-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull new ARM SoC support from Arnd Bergmann: "There are three SoC families newly dded to the 32-bit and 64-bit Arm architecture code in the kernel this time: - Daniel Palmer adds initial support for two chips made by MStar, a taiwanese SoC manufacturer that became part of Mediatek in 2012. For now, the added support is fairly minimal, with just two of its Cortex-A7 based 32-bit camera chips getting support for a limited set of on-chip peripherals. - Lars Povlsen from Microchip adds support for their new Sparx5 family of ethernet switch chips using 64-bit Cortex-A53 cores. These are descended from earlier VSC7xxx SparX and Ocelot chips using 32-bit MIPS cores. - Daniele Alessandrelli from Intel adds support for the new Keem Bay SoC for computer vision, built around a Movidius VPU with Linux running on Arm Cortex-A53 cores" * tag 'arm-newsoc-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (38 commits) ARM: mstar: Correct the compatible string for pmsleep dt-bindings: arm: mstar: remove the binding description for mstar,pmsleep dt-bindings: mfd: syscon: add compatible string for mstar,msc313-pmsleep ARM: mstar: Add reboot support ARM: mstar: Add "pmsleep" node to base dtsi ARM: mstar: Add PMU ARM: mstar: Adjust IMI size for infinity3 ARM: mstar: Adjust IMI size for mercury5 ARM: mstar: Adjust IMI size of infinity ARM: mstar: Add IMI SRAM region dt-bindings: arm: mstar: Move existing MStar binding descriptions dt-bindings: arm: mstar: Add binding details for mstar, pmsleep ARM: mstar: Fix dts filename for 70mai midrive d08 ARM: mstar: Add dts for 70mai midrive d08 ARM: mstar: Add dts for msc313(e) based BreadBee boards ARM: mstar: Add mercury5 series dtsis ARM: mstar: Add infinity/infinity3 family dtsis ARM: mstar: Add Armv7 base dtsi ARM: mstar: Add binding details for mstar,l3bridge ARM: mstar: Add machine for MStar/Sigmastar Armv7 SoCs ...
