pmdomain: samsung: Rework legacy splash-screen handover workaround

2025-11-04T16:16:05Z

Limit the workaround for the lack of the proper splash-screen handover handling to the legacy ARM 32bit systems and replace forcing a sync_state by explicite power domain shutdown. This approach lets compiler to optimize it out on newer ARM 64bit systems.

pmdomain: samsung: plug potential memleak during probe

2025-10-21T13:52:14Z

of_genpd_add_provider_simple() could fail, in which case this code leaks the domain name, pd->pd.name. Use devm_kstrdup_const() to plug this leak. As a side-effect, we can simplify existing error handling.

pmdomain: samsung: Fix splash-screen handover by enforcing a sync_state

2025-07-14T09:33:31Z

It's has been reported that some Samsung platforms fails to boot with genpd's new sync_state support. Typically the problem exists for platforms where bootloaders are turning on the splash-screen and handing it over to be managed by the kernel. However, at this point, it's not clear how to correctly solve the problem. Although, to make the platforms boot again, let's add a temporary hack in the samsung power-domain provider driver, which enforces a sync_state that allows the power-domains to be reset before consumer devices starts to be attached.

pmdomain: samsung: Move Kconfig option to the pmdomain subsystem

The Kconfig option belongs closer to the corresponding implementation, hence let's move it from the soc subsystem to the pmdomain subsystem. Cc: Krzysztof Kozlowski Cc: Alim Akhtar Cc: Signed-off-by: Ulf Hansson

pmdomain: Rename the genpd subsystem to pmdomain

2023-09-13T09:09:21Z

It has been pointed out that naming a subsystem "genpd" isn't very self-explanatory and the acronym itself that means Generic PM Domain, is known only by a limited group of people. In a way to improve the situation, let's rename the subsystem to pmdomain, which ideally should indicate that this is about so called Power Domains or "PM domains" as we often also use within the Linux Kernel terminology.
