soc: fsl: qe: check platform_driver_register() in qe_ic_of_init()

2026-09-14T11:40:26+00:00

[ Upstream commit fbdba2a67fa7c0e7570bcbf9f28b782d6100270d ]

qe_ic_of_init() ignored the return value of platform_driver_register()
and always returned success. Propagate the error to the initcall.

[ Upstream commit e460ef309f44b39480209970f1dd462f051d6f30 ]

The lack of get_direction() callback in this driver causes GPIOLIB to
emit a warning. Implement it.

soc: fsl: qe: properly scan GPIO nodes at startup

2026-09-14T11:40:12+00:00

[ Upstream commit e2414b289c2b68afab361def612ca3791cd70d12 ]

Before commit 156460811def ("soc: fsl: qe: Change GPIO driver to a
proper platform driver") qe_add_gpiochips() was walking the device
tree to find all nodes with compatible "fsl,mpc8323-qe-pario-bank".

After that commit the discovery is handled by the platform core,
therefore it is necessary to call of_platform_default_populate() on
the par_io node.

soc: qcom: pmic_glink_altmode: Define the TBT extradata properly

[ Upstream commit b255c6f4e6b48e09227cd68777a5d2ec1d36dc31 ]

Before the fixes-referenced commit, there was a trailing 'u32 reserved'
after the payload array. That commit gobbled it up into the thunderbolt
extradata. Push it back where it belongs.

There's no functional change, since the outer struct size remains
identical - struct usbc_sc8280x_tbt_data and therefore the union it's a
part of made up for the difference and the res bytes were ignored
anyway.

soc: ti: knav_qmss: Remove debugfs file on teardown

2026-09-14T11:39:37+00:00

[ Upstream commit 3c817862759913097f11467ed4ed2bbf974dabaf ]

knav_queue_probe() creates the global qmss debugfs file whose show
callback reads the global knav_qdev state. knav_queue_remove() tears
down the queue manager resources but leaves the debugfs file published.

Save the debugfs dentry in struct knav_device and remove it during
teardown before the resources used by the show callback are released.
While touching the debugfs_create_file() call, spell the unchanged read-
only file mode as 0444.

soc: qcom: rpmh-rsc: manage PM notifiers with devres

2026-09-14T11:39:24+00:00

[ Upstream commit 75e918aa876440d8ad559a11d6ab87bddb1ed79a ]

rpmh_rsc_probe() registers CPU PM or genpd notifiers before populating
child devices. If child population fails, the CPU PM notifier path is not
unwound and the genpd path needs open-coded cleanup.

Use devm_pm_runtime_enable() for the genpd path and
devm_add_action_or_reset() for both notifier registrations. This makes
probe failure and driver detach use the same cleanup model while keeping
devm_of_platform_populate() responsible for child devices.

soc: samsung: exynos-pmu: fix of_node refcount leak in exynos_get_pmu_regmap()

2026-09-14T11:39:04+00:00

[ Upstream commit fa476d53edd24e8105faace04e881b9c4179738f ]

exynos_get_pmu_regmap() obtains a device_node via of_find_matching_node()
and passes it to exynos_get_pmu_regmap_by_phandle(np, NULL). With
propname == NULL the callee uses np directly and does not drop a
reference, so the reference taken by of_find_matching_node() is leaked on
every call -- including on each -EPROBE_DEFER retry of the only in-tree
caller, exynos_retention_init() in the Exynos pinctrl driver.

Annotate np with the __free(device_node) cleanup attribute so the
reference is released when the function returns.

soc: qcom: geni-se: Use HW PROG_RAM_DEPTH to validate firmware size

2026-09-11T09:50:48+00:00

commit 522bfb4f33c0930b3d14d5c5ee80bc93a883b544 upstream.

The hardcoded MAX_GENI_CFG_RAMn_CNT limit is not accurate for all SoCs:
some targets have less CFG RAM than the constant implies, while others
like QCS615 need more entries than the old limit of 455 allowed, causing
valid firmware to be rejected at load time.

Rather than hardcoding a constant, read PROG_RAM_DEPTH from SE_HW_PARAM_2
at runtime to get the actual CFG RAM depth of the hardware instance and
use that as the upper bound for firmware size validation.
