iommu: Resolve fwspec ops automatically

2024-07-04T13:36:03Z

There's no real need for callers to resolve ops from a fwnode in order to then pass both to iommu_fwspec_init() - it's simpler and more sensible for that to resolve the ops itself. This in turn means we can centralise the notion of checking for a present driver, and enforce that fwspecs aren't allocated unless and until we know they will be usable. Also use this opportunity to modernise with some "new" helpers that arrived shortly after this code was first written; the generic fwnode_handle_get() clears up that ugly get/put mismatch, while of_fwnode_handle() can now abstract those open-coded dereferences.

ACPI / amba: Drop unnecessary check for registered amba_dummy_clk

2024-06-24T17:36:07Z

amba_register_dummy_clk() is called only once from acpi_amba_init() and acpi_amba_init() itself is called once during the initialisation. amba_dummy_clk can't be initialised before this in any other code path and hence the check for already registered amba_dummy_clk is not necessary. Drop the same. Signed-off-by: Youwan Wang Acked-by: Sudeep Holla Acked-by: Hanjun Guo Link: https://lore.kernel.org/r/20240624023101.369633-1-youwan@nfschina.com Signed-off-by: Catalin Marinas

dma-mapping: Add helpers for dma_range_map bounds

2024-04-26T10:07:24Z

Several places want to compute the lower and/or upper bounds of a dma_range_map, so let's factor that out into reusable helpers.

ACPI/IORT: Handle memory address size limits as limits

2024-04-26T10:07:23Z

Return the Root Complex/Named Component memory address size limit as an inclusive limit value, rather than an exclusive size. This saves having to fudge an off-by-one for the 64-bit case, and simplifies our caller.

coresight: debug: Move ACPI support from AMBA driver to platform driver

2024-04-16T10:30:47Z

Add support for the cpu debug devices in a new platform driver, which can then be used on ACPI based platforms. This change would now allow runtime power management for ACPI based systems. The driver would try to enable the APB clock if available. But first this renames and then refactors debug_probe() and debug_remove(), making sure they can be used both for platform and AMBA drivers.
