54ac76e13a pinctrl: renesas: rzg2l: Add PFC_OEN support for RZ/G3E SoC
Add support for configuring the PFC_OEN register on the RZ/G3E SoC to
enable output-enable control for specific pins. On this SoC, certain
pins such as TXC_TXCLK need to support switching between input and
output modes depending on the PHY interface mode (e.g., MII vs RGMII).
This functionality maps to the 'output-enable' property in the device
tree and requires explicit control via the PFC_OEN register.

This change updates the r9a09g047_variable_pin_cfg array to mark PB1, PE1,
PL0, PL1, PL2, and PL4 with the PIN_CFG_OEN flag to indicate output-enable
support. A new helper, rzg3e_pin_to_oen_bit(), is introduced to map these
pin names to their respective OEN bit positions, and the corresponding
callbacks are wired into the RZ/G3E SoC configuration using the generic
rzg2l_read_oen() and rzg2l_write_oen() accessors. Additionally, the GPIO
configuration for the PB, PE, and PL ports is updated to use the variable
port pack macro, enabling per-pin configuration necessary for OEN handling.

cd39805be8 pinctrl: renesas: rzg2l: Unify OEN handling across RZ/{G2L,V2H,V2N}
Unify the OEN handling on RZ/V2H(P) and RZ/V2N SoCs by reusing the existing
rzg2l_read_oen and rzg2l_write_oen functions from RZ/G2L. Add a
pin_to_oen_bit callback in rzg2l_pinctrl_data to look up per-pin OEN bit
positions, and introduce an oen_pwpr_lock flag in the hwcfg to manage PWPR
locking on SoCs that require it (RZ/V2H(P) family). Remove the hardcoded
PFC_OEN define and obsolete per-SoC OEN helpers.

Also drop redundant checks for the OEN offset in the suspend/resume paths,
as all supported SoCs now provide a valid offset through the `regs.oen`
field.

dd0d40d8f4 pinctrl: renesas: rzg2l: Remove OEN ops for RZ/G3E
The RZ/G3E pin controller does not advertise PIN_CFG_OEN capability, so
there is no valid mapping for output-enable bits on this SoC. Remove the
oen_read and oen_write callbacks from the RZ/G3E driver data to defer
OEN support until PIN_CFG_OEN support is added.

This is a preparatory change for future unification of OEN handling across
the driver.

a3455a0c24 pinctrl: renesas: rzg2l: Unify OEN access by making pin-to-bit mapping configurable
Refactor the RZG2L pinctrl driver to support reuse of the common
rzg2l_read_oen() and rzg2l_write_oen() helpers across SoCs with
different output-enable (OEN) bit mappings.

Introduce a new `pin_to_oen_bit` callback in `struct rzg2l_pinctrl_data`
to allow SoCs to provide custom logic for mapping a pin to its OEN bit.
Update the generic OEN read/write paths to use this callback when present.

With this change, SoCs like RZ/G3S can reuse the common OEN handling
code by simply supplying their own `pin_to_oen_bit` implementation.
The previously duplicated `rzg3s_oen_read()` and `rzg3s_oen_write()`
functions are now removed.

This improves maintainability and prepares the driver for supporting
future SoCs with minimal duplication.

27c76cc93c pinctrl: renesas: rzg2l: Parameterize OEN register offset
Prepare for supporting SoCs with varying OEN register locations by
parameterizing the OEN offset in the rzg2l driver. Introduce an `oen`
field in the rzg2l_register_offsets structure and update rzg2l_read_oen(),
rzg2l_write_oen(), suspend/resume caching, and SoC hwcfg entries to use
this offset instead of the hard-coded ETH_MODE value.

As part of this change, rename the field `eth_mode` in the register cache
to `oen` to better reflect its general purpose and decouple the naming
from a specific register.

8912b2862b pinctrl: renesas: rzg2l: Fix invalid unsigned return in rzg3s_oen_read()
rzg3s_oen_read() returns a u32 value, but previously propagated a negative
error code from rzg3s_pin_to_oen_bit(), resulting in an unintended large
positive value due to unsigned conversion. This caused incorrect
output-enable reporting for certain pins.

Without this patch, pins P1_0-P1_4 and P7_0-P7_4 are incorrectly reported
as "output enabled" in the pinconf-pins debugfs file. With this fix, only
P1_0-P1_1 and P7_0-P7_1 are shown as "output enabled", which matches the
hardware manual.

Fix this by returning 0 when the OEN bit lookup fails, treating the pin
as output-disabled by default.

78b72897a5 soc: samsung: exynos-pmu: Enable CPU Idle for gs101
Register cpu pm notifiers for gs101 which call the
gs101_cpu_pmu_online/offline callbacks which in turn program the ACPM
C2 hint. This hint is required to actually enter the C2 idle state in
addition to the PSCI calls due to limitations in the el3mon/ACPM firmware.

A couple of corner cases are handled, namely when the system is rebooting
or suspending we ignore the request. Additionally the request is ignored if
the CPU is in CPU hot plug. Some common code is refactored so that it can
be called from both the CPU hot plug callbacks and CPU PM notifier taking
into account that CPU PM notifiers are called with IRQs disabled whereas
CPU hotplug callbacks are not.

Additionally due to CPU PM notifiers using raw_spinlock the locking is
updated to use raw_spinlock variants, this includes updating the pmu_regs
regmap to use .use_raw_spinlock = true and additionally creating and
registering a custom  pmu-intr-gen regmap instead of using the regmap
provided by syscon.

Note: this patch has a runtime dependency on adding 'local-timer-stop' dt
property to the CPU nodes. This informs the time framework to switch to a
broadcast timer as the local timer will be shutdown. Without that DT
property specified the system hangs in early boot with this patch applied.

32e0d669f3 cpufreq: mediatek-hw: Add support for MT8196
The MT8196 SoC uses DVFS to set a desired target frequency for each CPU
core. It also uses slightly different register offsets.

Add support for it, which necessitates reworking how the mmio regs are
acquired, as mt8196 has the fdvfs register before the performance domain
registers.

I've verified with both `sysbench cpu run` and `head -c 10G \
/dev/urandom | pigz -p 8 -c - | pv -ba > /dev/null` that we don't just
get a higher reported clock frequency, but that the observed performance
also increases, by a factor of 2.64 in an 8 thread sysbench test.

35eb6b7885 cpufreq: mediatek-hw: Separate per-domain and per-instance data
As it stood, the mediatek cpufreq driver could get away with never
really having a private driver instance struct. This is because all data
was stored in the per-domain structs.

However, this complicates matters when actual per-instance data like the
variant struct is introduced. Instead of having a pointer to it for
every domain, have a pointer to a global "priv" struct that can be
extended over time, and rename the "data" struct to "domain" to
distinguish its purpose better.

2f5178abb9 cpufreq: mediatek-hw: Refactor match data into struct
While the driver could get away with having the per-compatible match
data just be an array of the reg offsets, the only thing it used it for
right now, this doesn't really allow it to be extended in any meaningful
way if some other per-variant information needs to be communicated.

In preparation of adding support for hybrid "FDVFS" for MT8196, refactor
the code to make the DT match data a struct, which currently only
contains a single member: the reg offsets. This will allow this struct
to be extended with other members for other hardware variants.

62498af7b1 dt-bindings: cpufreq: Add mediatek,mt8196-cpufreq-hw binding
The MediaTek MT8196 SoC has new cpufreq hardware, with added memory
register ranges to control Dynamic-Voltage-Frequency-Scaling.

The DVFS hardware is controlled through a set of registers referred to
as "FDVFS". They set the target frequency the DVFS hardware should aim
for for each performance domain.

Instead of working around the old binding and its already established
meanings for the reg items, add a new binding. The FDVFS register memory
region is at the beginning, which allows us to easily expand this
binding for future SoCs which may have more than 3 performance domains.

Use the hmac_sha256_usingrawkey() library function instead of the
"hmac(sha256)" crypto_shash.  This is simpler and faster.

As a cleanup, change the input data parameters from "challenge,
sizeof(hmac)" to "challenge, sizeof(challenge)", so that the size is
being taken of the correct buffer.  This is not a functional change,
since it happens that sizeof(hmac) == sizeof(challenge).

Replace the selection of CRYPTO and CRYPTO_HASH with CRYPTO_LIB_SHA256
and CRYPTO_LIB_UTILS.  The latter is needed for crypto_memneq() which
was previously being pulled in via CRYPTO.

5068b52548 dmaengine: qcom: bam_dma: Fix DT error handling for num-channels/ees
When we don't have a clock specified in the device tree, we have no way to
ensure the BAM is on. This is often the case for remotely-controlled or
remotely-powered BAM instances. In this case, we need to read num-channels
from the DT to have all the necessary information to complete probing.

However, at the moment invalid device trees without clock and without
num-channels still continue probing, because the error handling is missing
return statements. The driver will then later try to read the number of
channels from the registers. This is unsafe, because it relies on boot
firmware and lucky timing to succeed. Unfortunately, the lack of proper
error handling here has been abused for several Qualcomm SoCs upstream,
causing early boot crashes in several situations [1, 2].

Avoid these early crashes by erroring out when any of the required DT
properties are missing. Note that this will break some of the existing DTs
upstream (mainly BAM instances related to the crypto engine). However,
clearly these DTs have never been tested properly, since the error in the
kernel log was just ignored. It's safer to disable the crypto engine for
these broken DTBs.
