The bit-wise and of the action field with MLX5_ACCEL_ESP_ACTION_DECRYPT
is incorrect as MLX5_ACCEL_ESP_ACTION_DECRYPT is zero and not intended
to be a bit-flag. Fix this by using the == operator as was originally
intended.

Hello again after easter,
I have looked little bit more at sn65* driver and its application to
have better background.
I miss only info what panel do you have, how it is enabled/power controlled.

Regmap operations can fail if the underlying subsystem is not working

As this is useful information for the user, print an error message if it

Previously, the last used PWM channel could change the global prescale
setting, even if other channels are already in use.
Fix it by only allowing the first enabled PWM to change the global
chip-wide prescale setting. If there is more than one channel in use,
the prescale settings resulting from

The PCA9685 supports staggered LED output ON times to minimize current
surges and reduce EMI.
When the PWM_STAGGERING_ALLOWED flag is set for a channel, its ON time
is delayed by channel number x counter range / 16, which avoids
asserting all the enabled outputs at the same counter value while
If the flag PWM_STAGGERING_ALLOWED is set on a channel, the PWM driver
may (if supported by the HW) delay the ON time of the channel relative
to the channel number.
This does not alter the duty cycle ratio and is only relevant for PWM
chips with less prescalers than channels, which would otherwise
Add the flag and corresponding documentation for the new PWM staggering
mode feature.

Implements .get_state to read-out the current hardware state.
The hardware readout may return slightly different values than those
that were set in apply due to the limited range of possible prescale and
counter register values.
Also note that although the datasheet mentions 200 Hz as default
The switch to the atomic API goes hand in hand with a few fixes to
previously experienced issues:
- The duty cycle is no longer lost after disable/enable (previously the

The IOMMU driver calculates the guest addressability for a DMA request
based on the value of the mgaw reported from the IOMMU. However, this
is a fused value and as mentioned in the spec, the guest width

Right now, if a call to kvm_tdp_mmu_zap_sp returns false, the caller
will skip the TLB flush, which is wrong. There are two ways to fix
it:
- since kvm_tdp_mmu_zap_sp will not yield and therefore will not flush
the TLB itself, we could change the call to kvm_tdp_mmu_zap_sp to
use "flush |=

This patch adds DFL bus driver for the Altera SPI Master

When sg_alloc_table_from_pages is called with n_pages = 0, we write in a

Remove camelcase in some symbols defined in Hal8723BReg.h. These symbols
are not used anywhere else, therefore this patch does not break the driver.

Commit 8c182bd7 ("ACPI: processor: Fix CPU0 wakeup in
acpi_idle_play_dead()") tried to fix CPU0 hotplug breakage by copying
wakeup_cpu0() + start_cpu0() logic from hlt_play_dead()//mwait_play_dead()
into acpi_idle_play_dead(). The problem is that these functions are not
exported to modules so

Implement support for PSF mitigation via kernel parameters.
On AMD processors that support Predictive Store Forwarding(PSF),
the disabling of Speculative Store Bypass(SSB) will also disable PSF.
Two kernel parameters are being introduced to enable PSF
mitigation.
From: Ramakrishna Saripalli
All AMD processors that support Predictive Store Forwarding (PSF)
provide a CPUID bit to detect support for mitigation of this
feature. This bit is referred to as PSFD (Predictive Store Forwarding
Disable)
If CPU advertises PSFD:
- Advertise a generic feature
From: Ramakrishna Saripalli
Certain AMD processors feature a new technology called Predictive Store
Forwarding (PSF).
PSF is a micro-architectural optimization designed to improve the
performance of code execution by predicting dependencies between
loads and stores.
