dc9a897d - pmdomain: thead: Add power-domain driver for TH1520

Tue, 11 Mar 2025 17:18:59 +0000

pmdomain: thead: Add power-domain driver for TH1520The T-Head TH1520 SoC contains multiple power islands that can beprogrammatically turned on and off using the AON (Always-On) protocoland a hardware mailbox [1]. The relevant mailbox driver has already beenmerged into the mainline kernel in commit 5d4d263e1c6b ("mailbox:Introduce support for T-head TH1520 Mailbox driver");Introduce a power-domain driver for the TH1520 SoC, which is using AONfirmware protocol to communicate with E902 core through the hardwaremailbox. This way it can send power on/off commands to the E902 core.The interaction with AUDIO power island e.g trying to turn it OFF provedto crash the firmware running on the E902 core. Introduce the workaroundto disable interacting with the power island.[1]Link: https://openbeagle.org/beaglev-ahead/beaglev-ahead/-/blob/main/docs/TH1520%20System%20User%20Manual.pdfSigned-off-by: Michal Wilczynski Acked-by: Drew Fustini Link: https://lore.kernel.org/r/20250311171900.1549916-5-m.wilczynski@samsung.comSigned-off-by: Ulf Hansson List of files: /linux-6.15/drivers/pmdomain/Makefile

d6948c13 - PM: domains: Move genpd and its governor to the pmdomain subsystem

Wed, 13 Dec 2023 11:33:05 +0000

PM: domains: Move genpd and its governor to the pmdomain subsystemIt seems reasonable to collect the core parts for the generic PM domain,along with its corresponding provider drivers. Therefore let's move thefiles from drivers/base/power/ to drivers/pmdomain/ and while at it, let'salso rename the files accordingly.Moreover, let's also update MAINTAINERS to reflect the update.Cc: Kevin Hilman Signed-off-by: Ulf Hansson Acked-by: Rafael J.

2af23ceb - pmdomain: arm: Add the SCMI performance domain

Tue, 19 Sep 2023 12:16:05 +0000

pmdomain: arm: Add the SCMI performance domainTo enable support for performance scaling (DVFS) for generic devices withthe SCMI performance protocol, let's add an SCMI performance domain. Thisis being modelled as a genpd provider, with support for performance scalingthrough genpd's ->set_performance_state() callback.Note that, this adds the initial support that allows consumer drivers forattached devices, to vote for a new performance state via calling thedev_pm_genpd_set_performance_state(). However, this should be avoided asit's in most cases preferred to use the OPP library to vote for a new OPPinstead. The support using the OPP library isn't part of this change, butneeds to be implemented from subsequent changes.Signed-off-by: Ulf Hansson Link: https://lore.kernel.org/r/20230919121605.7304-1-ulf.hansson@linaro.orgSigned-off-by: Sudeep Holla List of files: /linux-6.15/drivers/pmdomain/Makefile

e2ad626f - pmdomain: Rename the genpd subsystem to pmdomain

Tue, 12 Sep 2023 22:11:27 +0000

pmdomain: Rename the genpd subsystem to pmdomainIt has been pointed out that naming a subsystem "genpd" isn't veryself-explanatory and the acronym itself that means Generic PM Domain, isknown 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.Suggested-by: Rafael J.
