Commit 7aa1aa6ecec2 ("QE: Move QE from arch/powerpc to drivers/soc")
moved QE into drivers/soc including gpio.c but left CONFIG_QE_GPIO
in powerpc's Kconfig.
Move it to SoC as well as it is the only place it is used:
drivers/soc/fsl/qe/Makefile:obj-$(CONFIG_QE_GPIO) += gpio.o qe_ports_ic.o
include/soc/fsl/qe/qe.h:#ifdef CONFIG_QE_GPIO
include/soc/fsl/qe/qe.h:#endif /* CONFIG_QE_GPIO */
There is also a dependency in USB subsystem for CONFIG_USB_FHCI_HCD:
drivers/usb/host/Kconfig: depends on QE_GPIO && QUICC_ENGINE
Because that USB driver selects CONFIG_FSL_GTM which is specific to
powerpc, it has to depend on CONFIG_PPC.

The driver has an OF match table wired to .of_match_table, but does
not export the table with MODULE_DEVICE_TABLE().
Add the missing MODULE_DEVICE_TABLE(of, ...) entry so module alias
information is generated for OF based module autoloading.
This is a source-level fix. It does not claim dynamic hardware
reproduction; the evidence is the driver-owned match table, its use by
the platform driver, and the missing module alias publication.

put_fifo_with_discard() acts as both producer and consumer on the kfifo:
it calls kfifo_skip() (advances out) and kfifo_put() (advances in) from
the IRQ handler without synchronizing with snoop_file_read(), which also
consumes via kfifo_to_user(). On SMP systems this concurrent access can
leave (in - out) larger than the ring buffer, so __kfifo_to_user()'s clamp
to (in - out) is ineffective and kfifo_copy_to_user() can attempt a
copy_to_user() past the kmalloc-2k backing store:
usercopy: Kernel memory exposure attempt detected from SLUB object
'kmalloc-2k' (offset 0, size 2049)!
kernel BUG at mm/usercopy.c!
Call trace:
usercopy_abort
__check_heap_object
__check_object_size
kfifo_copy_to_user
__kfifo_to_user
snoop_file_read
vfs_read
Serialize kfifo access with a per-channel spinlock shared between the
IRQ handler (producer) and the file reader (consumer). Annotate @fifo
with __guarded_by(&lock) and opt the driver into context analysis so the
compiler enforces that all fifo access holds the lock.

On Shikra, the DDR System Firmware (DSF) configures ECC interrupt
routing before the kernel driver probes — it enables Tag/Data RAM
interrupts and programs error thresholds in the LLCC interrupt-enable
registers.
Set irq_configured in shikra_cfg so that qcom_llcc_edac_probe() skips
calling qcom_llcc_core_setup(), which would otherwise overwrite the
firmware-managed register state with redundant writes.

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.

teardown before the resources used by the show callback are released.

The kernel does not permit a device to register multiple sys-off
handlers for non-default priority levels. Hence, for multi-socket Tegra
devices, registering the sys-off handler in the Tegra PMC driver (which
uses the low priority level) more than once fails.
The Tegra PMC sys-off handler is supported for all current generations
of the Tegra SoC, however, it is only used as a low priority handler if
everything else fails. For example, on Tegra264 the EFI reboot handler
is called to restart the device. Therefore, for multi-socket devices,
skip the registering of the sys-off handler to because this is not
critical.

Apple SoCs have PMGR blocks that control a bunch of power-related
features. Besides the existing device power state controls (which are
very uniform and handled by apple-pmgr-pwrstate), we also need to manage
more random registers such as SoC-wide fabric and memory controller
power states, which have a different interface.
Add a driver for these kitchen sink controls. Right now it implements
fabric and memory controller power state switching on system
standby/s2idle, which saves about 1W of power or so on t60xx platforms.

In preparation for a refactoring of multimedia related MediaTek
drivers, including mmsys, mutex and mediatek-drm, rework all of
the MMSYS routes to specify a hardware component instance number
(or "SubID") alongside the hardware component type.
This also is one step of preparation towards the removal of the
catch-all mtk_ddp_comp_id enumeration and towards the migration
from a predefined-coupling static hardware component IDSubID
mapping (carrying around a very long enumeration and also some
multiple big arrays in mediatek-drm) to a more flexible map of
Component ID (Type) decoupled from Component SubID (HW Instance)
as then, anyway, techniques to handle components are always the
same on a type basis.

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.

The drivers for Qualcomm SoC components are covering a basic or
fundamental SoC blocks. Usually they are required for booting or to
achieve basic expected functionality when running Linux. These drivers
do not represent any sort of buses visible to the board
designers/configurators, thus they should be always enabled, regardless
how SoC is used in the final board.
Kernel configuration should not ask users choice of drivers when that
choice is obvious and known to the developers that answer should be
'yes' or 'module'.
Switch most of the Qualcomm SoC drivers to a default 'yes' or
'module' for ARCH_QCOM, to match existing defconfig usage.
This has no impact on arm64 defconfig, arm qcom_defconfig and arm
multi_v7_defconfig.
multi:
+#define CONFIG_QCOM_PDR_HELPERS_MODULE 1
+#define CONFIG_QCOM_PBS_MODULE 1
+#define CONFIG_QCOM_AOSS_QMP 1
+#define CONFIG_QCOM_APR_MODULE 1
+#define CONFIG_QCOM_LLCC_MODULE 1
qcom:
+#define CONFIG_QCOM_PDR_HELPERS_MODULE 1
+#define CONFIG_QCOM_PBS_MODULE 1
+#define CONFIG_QCOM_AOSS_QMP 1
+#define CONFIG_QCOM_APR_MODULE 1
+#define CONFIG_QCOM_SPM 1
+#define CONFIG_QCOM_LLCC_MODULE 1
The change will however enable by default all drivers for arm or arm64
COMPILE_TEST builds, whenever ARCH_QCOM is selected, which feels
logical: if one selects ARCH_QCOM then probably by default wants to
build test it entirely. Kernels with COMPILE_TEST are not supposed to
be used for booting.

There is no point to allow selecting core SoC drivers for Qualcomm ARMv7
SoCs when building ARM64 kernel, and vice versa.
This makes kernel configuration more difficult as many do not remember
the Qualcomm SoCs model names/numbers and their properties like
architecture. No features should be lost because:
1. There won't be a single image for ARMv7 and ARMv8/9 SoCs.
2. Newer ARMv8/9 SoCs won't be running in arm32 emulation mode.

Switch from a simple menu to menuconfig, so all Qualcomm SoC drivers
will be under one selectable option, allowing to disable them all which
should make kernel configuration easier when preparing a non-Qualcomm
kernel.
This has few benefits (functional impact of this commit):
1. Allow compile testing of QCOM_OCMEM, which previously required
ARCH_QCOM.
2. Hide behind ARCH_QCOM or COMPILE_TEST drivers specific to Qualcomm
which should not be available to other kernel builds:
QCOM_PMIC_PDCHARGER_ULOG, QCOM_PMIC_GLINK, QCOM_SPM and QCOM_PBS.

as well. So extend the version check to support versions 3 and beyond.

UBWC devices before 4.0 use standard UBWC swizzle levels. As all the
drivers now use the qcom_ubwc_swizzle() helper, move those values to the
helper, leaving UBWC 4.0+ intact for now.

All the users have been migrated to using qcom_ubwc_macrotile_mode()
instead of reading the raw value from the config structure. Drop the
field from struct qcom_ubwc_cfg_data and replace it with the calculated
value. Split single UBWC_3_0 into UBWC_3_0 (no macrotile mode) and
UBWC_3_1 (with macrotile mode).

According to the documentation, UBWC bank spreading should be enabled
for all targets. It's just not all targets have separate bit to control
it. Drop the bit from the database and make the helper always return
true. If we need to change it later, the helper can be adjusted
according to the programming guides.

The ubwc_dec_version field has been inherited from the MDSS driver and
it is equal to the version of the UBWC decoder in the display block
only. Other IP Cores can have different UBWC decoders and so the version
would vary between blocks.
As the value is no longer used as is not relevant to other UBWC database
consumers, drop it from the UBWC database.

devm_apple_sart_get() obtains the supplier platform device and attempts
to create a runtime-PM device link to it, but it ignores device_link_add()
failure. A consumer can then continue without the dependency that keeps
the SART supplier ordered and runtime-PM reachable.
Treat a failed device link as an error and drop the supplier device
reference before returning.

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.
Found by static analysis tool CodeQL.
