pmdomain: core: fix unused variable warning with !PM_GENERIC_DOMAINS_OF

2026-06-15T19:12:35Z

The genpd provider bus is really only used when CONFIG_PM_GENERIC_DOMAINS_OF is enabled, and since the recent deferred initialisation of domain parent devices, the root device pointer is otherwise unused. Fix the unused variable warning by moving the definition of the root device pointer inside the corresponding ifdef.

pmdomain: core: fix early domain registration

2026-06-11T14:05:45Z

A recent change switching to a dynamically allocated root device broke platforms like rcar-sysc that registers PM domains before the PM domain bus itself has been registered (cf. commit c5ae5a0c6112 ("pmdomain: renesas: rcar-sysc: Add genpd OF provider at postcore_initcall")). Defer the assignment of the parent root device until the domain is registered with driver core to avoid it being left unset.

pmdomain: imx: fix OF node refcount

2026-06-03T09:49:37Z

for_each_child_of_node_scoped() decrements the reference count of the nod after each iteration. Assigning it without incrementing the refcount to a dynamically allocated platform device will result in a double put in platform_device_release(). Add the missing call to of_node_get().

pmdomain: sunxi: support power domain flags for pck600

2026-06-03T09:30:38Z

While bringing up the PowerVR GPU on the A733 (Radxa Cubie A7Z), we found that one of the GPU power domains must be configured as "always on." While the Radxa BSP device tree leaves the GPU power domain nodes commented out, the GPU driver code contains traces indicating an "always on" requirement [1]. Currently, sunxi_pck600_desc only supports specifying pd_names. This patch introduces sunxi_pck600_pd_desc, which stores both the name and its associated flags. This also (more or less) aligns the implementation with the existing sun50i PPU handling of always-on domains. With this change, individual power domains can now be configured more granularly. In particular, the GPU_CORE domain in sun60i_a733_pck600_pds can now be explicitly marked with GENPD_FLAG_ALWAYS_ON. The patch was tested on the Radxa Cubie A7Z, where the GPU now functions as expected. Thanks to Icenowy for her support and expertise on sunxi and PowerVR, and thanks to Mikhail for identifying this exact cause of the GPU bring-up issue.

pmdomain: core: switch to dynamic root device

2026-06-03T09:08:24Z

Driver core expects devices to be dynamically allocated and will, for example, complain loudly if a device that lacks a release function is ever freed. Use root_device_register() to allocate and register the root device instead of open coding using a static device. Signed-off-by: Johan Hovold Signed-off-by: Ulf Hansson
