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: "A number of new drivers get added this time, along with many low-priority bugfixes. The most interesting changes by subsystem are: bus drivers: - Updates to the Broadcom bus interface driver to support newer SoC types - The TI OMAP sysc driver now supports updated DT bindings memory controllers: - A new driver for Tegra186 gets added - A new driver for the ti-emif sram, to allow relocating suspend/resume handlers there SoC specific: - A new driver for Qualcomm QMI, the interface to the modem on MSM SoCs - A new driver for power domains on the actions S700 SoC - A driver for the Xilinx Zynq VCU logicoreIP reset controllers: - A new driver for Amlogic Meson-AGX - various bug fixes tee subsystem: - A new user interface got added to enable asynchronous communication with the TEE supplicant. - A new method of using user space memory for communication with the TEE is added" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (84 commits) of: platform: fix OF node refcount leak soc: fsl: guts: Add a NULL check for devm_kasprintf() bus: ti-sysc: Fix smartreflex sysc mask psci: add CPU_IDLE dependency soc: xilinx: Fix Kconfig alignment soc: xilinx: xlnx_vcu: Use bitwise & rather than logical && on clkoutdiv soc: xilinx: xlnx_vcu: Depends on HAS_IOMEM for xlnx_vcu soc: bcm: brcmstb: Be multi-platform compatible soc: brcmstb: biuctrl: exit without warning on non brcmstb platforms Revert "soc: brcmstb: Only register SoC device on STB platforms" bus: omap: add MODULE_LICENSE tags soc: brcmstb: Only register SoC device on STB platforms tee: shm: Potential NULL dereference calling tee_shm_register() soc: xilinx: xlnx_vcu: Add Xilinx ZYNQMP VCU logicoreIP init driver dt-bindings: soc: xilinx: Add DT bindings to xlnx_vcu driver soc: xilinx: Create folder structure for soc specific drivers of: platform: populate /firmware/ node from of_platform_default_populate_init() soc: samsung: Add SPDX license identifiers soc: qcom: smp2p: Use common error handling code in qcom_smp2p_probe() tee: shm: don't put_page on null shm->pages ...
