ARM: samsung: exynos5250: Allow CPU1 to boot

2026-02-26T21:13:27+00:00

The firmware trustzone needs a special call to bring up the secondary cpu core on the Manta board. This seems to be not needed on other exynos5 boards and comes down to the available firmware on a particular board.

ARM: exynos: Simplify with scoped for each OF child loop

Use scoped for-each loop when iterating over device nodes to make code a bit simpler. Reviewed-by: Jonathan Cameron Signed-off-by: Krzysztof Kozlowski Link: https://patch.msgid.link/20260109-of-for-each-compatible-scoped-v3-3-c22fa2c0749a@oss.qualcomm.com Signed-off-by: Rob Herring (Arm)

syscore: Pass context data to callbacks

2025-11-14T09:01:52+00:00

Several drivers can benefit from registering per-instance data along with the syscore operations. To achieve this, move the modifiable fields out of the syscore_ops structure and into a separate struct syscore that can be registered with the framework. Add a void * driver data field for drivers to store contextual data that will be passed to the syscore ops. Acked-by: Rafael J. Wysocki (Intel) Signed-off-by: Thierry Reding

ARM: Switch to irq_domain_create_*()

2025-05-16T19:06:08+00:00

irq_domain_add_*() interfaces are going away as being obsolete now. Switch to the preferred irq_domain_create_*() ones. Those differ in the node parameter: They take more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the original parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

Pull ARM SoC updates from Arnd Bergmann: "These are mostly minor cleanups and bugfixes that address harmless problems. The largest branch is a conversion of the omap platform to use GPIO descriptors throughout the tree, for any devices that are not fully converted to devicetree.

ARM: exynos: Re-introduce Exynos4212 support

2023-05-09T17:44:30+00:00

Support for the Exynos4212 SoC was originally dropped as there were no boards using it. We will be adding a device that uses it, so add back the relevant code. This reverts commit 9e43eca3c87476f75680f472ff3ebcd85f357b86.

ARM: EXYNOS: Use of_address_to_resource()

2023-03-22T17:47:01+00:00

Replace of_get_address() and of_translate_address() with single call to of_address_to_resource(). With this, use ioremap() instead of of_iomap() which would parse "reg" a second time.

ARM: exynos: Use of_property_read_bool() for boolean properties

2023-03-13T06:55:26+00:00

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. Convert reading boolean properties to to of_property_read_bool().

ARM: exynos: Fix refcount leak in exynos_map_pmu

2022-06-06T08:40:57+00:00

of_find_matching_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak. of_node_put() checks null pointer.
