Merge tag 'arm-soc-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC updates from Arnd Bergmann: "One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well. Across platforms, there is ongoing cleanup, with Geert and Rob revisiting some a lot of Kconfig options" * tag 'arm-soc-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (94 commits) ARM: omap2: fix omap5_realtime_timer_init definition ARM: zynq: Don't select CONFIG_ICST ARM: OMAP2+: Fix regression for using local timer on non-SMP SoCs clk: versatile: Fix kconfig dependency on COMMON_CLK_VERSATILE ARM: davinci: fix build failure without I2C power: reset: vexpress: fix build issue power: vexpress: cleanup: use builtin_platform_driver power: vexpress: add suppress_bind_attrs to true Revert "ARM: vexpress: Don't select VEXPRESS_CONFIG" MAINTAINERS: pxa: remove Compulab arm/pxa support ARM: pxa: remove Compulab pxa2xx boards bus: arm-integrator-lm: Fix return value check in integrator_ap_lm_probe() soc: imx: move cpu code to drivers/soc/imx ARM: imx: move cpu definitions into a header ARM: imx: use device_initcall for imx_soc_device_init ARM: imx: pcm037: make pcm970_sja1000_platform_data static bus: ti-sysc: Timers no longer need legacy quirk handling ARM: OMAP2+: Drop old timer code for dmtimer and 32k counter ARM: dts: Configure system timers for omap2 ARM: dts: Configure system timers for ti81xx ...
