Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC fixes from Arnd Bergmann: "A few smaller fixes for v5.7-rc3: The majority are fixes for bugs I found after restarting my randconfig build testing that had been dormant for a while. On the Nokia N950/N9 phone, a DT fix is required to address a boot regression. For the bcm283x (Raspberry Pi), two DT fixes address minor issues" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: soc: imx8: select SOC_BUS soc: tegra: fix tegra_pmc_get_suspend_mode definition soc: fsl: dpio: avoid stack usage warning soc: fsl: dpio: fix incorrect pointer conversions ARM: imx: provide v7_cpu_resume() only on ARM_CPU_SUSPEND=y ARM: dts: bcm283x: Disable dsi0 node firmware: xilinx: make firmware_debugfs_root static drivers: soc: xilinx: fix firmware driver Kconfig dependency ARM: dts: bcm283x: Add cells encoding format to firmware bus ARM: dts: OMAP3: disable RNG on N950/N9
