firmware: imx: scu-irq: Set mu_resource_id before get handle

2026-01-30T09:27:22+00:00

commit ff3f9913bc0749364fbfd86ea62ba2d31c6136c8 upstream. mu_resource_id is referenced in imx_scu_irq_get_status() and imx_scu_irq_group_enable() which could be used by other modules, so need to set correct value before using imx_sc_irq_ipc_handle in SCU API call.

[ Upstream commit 81fb53feb66a3aefbf6fcab73bb8d06f5b0c54ad ] With mailbox channel requested, there is possibility that interrupts may come in, so need to make sure the workqueue is initialized before the queue is scheduled by mailbox rx callback.

[ Upstream commit ee67247843a2b62d1473cfa4df300e69b5190ccf ] imx_scu_enable_general_irq_channel() calls of_parse_phandle_with_args(), but does not release the OF node reference. Add a of_node_put() call to release the reference.

Pull ARM SoC driver updates from Arnd Bergmann: "The main change this time was the introduction of the drivers/genpd subsystem that gets split out from drivers/soc to keep common functionality together. The SCMI driver subsystem gets an update to version 3.2 of the specification. There are also updates to memory, reset and other firmware drivers. On the soc driver side, the updates are mostly cleanups across a number of Arm platforms. On driver for loongarch adds power management for DT based systems, another driver is for HiSilicon's Arm server chips with their HCCS system health interface.

firmware: Explicitly include correct DT includes

2023-08-12T08:31:01+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
