Pull ARM SoC fixes from Arnd Bergmann: "A number of fixes have accumulated, but they are largely for harmless issues: - Several OF node leak fixes - A fix to the Exynos7885 UART clock description - DTS fixes to prevent boot failures on TI AM64 and J721s2 - Bus probe error handling fixes for Baikal-T1 - A fixup to the way STM32 SoCs use separate dts files for different firmware stacks - Multiple code fixes for Arm SCMI firmware, all dealing with robustness of the implementation - Multiple NXP i.MX devicetree fixes, addressing incorrect data in DT nodes - Three updates to the MAINTAINERS file, including Florian Fainelli taking over BCM283x/BCM2711 (Raspberry Pi) from Nicolas Saenz Julienne" * tag 'soc-fixes-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (29 commits) ARM: dts: aspeed: nuvia: rename vendor nuvia to qcom arm: mach-spear: Add missing of_node_put() in time.c ARM: cns3xxx: Fix refcount leak in cns3xxx_init MAINTAINERS: Update email address arm64: dts: ti: k3-am64-main: Remove support for HS400 speed mode arm64: dts: ti: k3-j721s2: Fix overlapping GICD memory region ARM: dts: bcm2711-rpi-400: Fix GPIO line names bus: bt1-axi: Don't print error on -EPROBE_DEFER bus: bt1-apb: Don't print error on -EPROBE_DEFER ARM: Fix refcount leak in axxia_boot_secondary ARM: dts: stm32: move SCMI related nodes in a dedicated file for stm32mp15 soc: imx: imx8m-blk-ctrl: fix display clock for LCDIF2 power domain ARM: dts: imx6qdl-colibri: Fix capacitive touch reset polarity ARM: dts: imx6qdl: correct PU regulator ramp delay firmware: arm_scmi: Fix incorrect error propagation in scmi_voltage_descriptors_get firmware: arm_scmi: Avoid using extended string-buffers sizes if not necessary firmware: arm_scmi: Fix SENSOR_AXIS_NAME_GET behaviour when unsupported ARM: dts: imx7: Move hsic_phy power domain to HSIC PHY node soc: bcm: brcmstb: pm: pm-arm: Fix refcount leak in brcmstb_pm_probe MAINTAINERS: Update BCM2711/BCM2835 maintainer ...

bus: mhi: host: Move IRQ allocation to controller registration phase

2022-06-24T07:24:19+00:00

During runtime, the MHI endpoint may be powered up/down several times. So instead of allocating and destroying the IRQs all the time, let's just enable/disable IRQs during power up/down. The IRQs will be allocated during mhi_register_controller() and freed during mhi_unregister_controller(). This works well for things like PCI hotplug also as once the PCI device gets removed, the controller will get unregistered. And once it comes back, it will get registered back and even if the IRQ configuration changes (MSI), that will get accounted.

Cinterion MV31-W modem with a new baseline (firmware) is sold as a separate product with different device ID. So add support for the same reusing the config.

bus: bt1-axi: Don't print error on -EPROBE_DEFER

2022-06-14T10:21:44+00:00

The Baikal-T1 AXI bus driver correctly handles the deferred probe situation, but still pollutes the system log with a misleading error message. Let's fix that by using the dev_err_probe() method to print the log message in case of the clocks/resets request errors.

bus: fsl-mc-bus: fix KASAN use-after-free in fsl_mc_bus_remove()

2022-06-10T13:53:12+00:00

In fsl_mc_bus_remove(), mc->root_mc_bus_dev->mc_io is passed to fsl_destroy_mc_io(). However, mc->root_mc_bus_dev is already freed in fsl_mc_device_remove(). Then reference to mc->root_mc_bus_dev->mc_io triggers KASAN use-after-free. To avoid the use-after-free, keep the reference to mc->root_mc_bus_dev->mc_io in a local variable and pass to fsl_destroy_mc_io(). This patch needs rework to apply to kernels older than v5.15.
