In contexts like suspend, shutdown and error handling, we need to suspend
devfreq to make sure these contexts won't be disturbed by clock scaling.
However, suspending devfreq is not enough since users can still trigger a
clock scaling by manipulating the sysfs node clkscale_enable and devfreq
sysfs
ufshcd_hba_exit() is always called after ufshcd_exit_clk_scaling() and
ufshcd_exit_clk_gating(), so no need to suspend clock scaling again in
ufshcd_hba_exit().

Although the SMCCC specification provides some limited functionality for
describing the presence of hypervisor and firmware services, this is
generally applicable only to functions designated as "Arm Architecture
Service Functions" and no portable discovery mechanism is provided
ptp_kvm will get this service through SMCC call.
The service offers wall time and cycle count of host to guest.
The caller must specify whether they want the host cycle count
or the difference between host cycle count and cntvoff.

Currently, there is no mechanism to keep time sync between guest and host
in arm/arm64 virtualization environment. Time in guest will drift compared
with host after boot up as they may both use third party time sources
to correct their time respectively. The time deviation will be in order

PTP_KVM implementation depends on hypercall using SMCCC. So we
introduce a new SMCCC service ID. This doc explains how does the

Currently, we offen use ntp (sync time with remote network clock)
to sync time in VM. But the precision of ntp is subject to network delay
so it's difficult to sync time in a high precision.
kvm virtual ptp clock (ptp_kvm) offers another way to sync time in VM,
as the remote clock locates in the h

EIC controller have unfixed numbers of banks on different Spreadtrum SoCs,
and each bank has its own base address, the loop of getting there base
address in driver should break if the resource gotten via

The SoundWire bus code confuses bus and Slave device levels for
dev_err/dbg logs. That's not impacting functionality but the accuracy
of kernel logs.
We should only use bus->dev for bus-level operations and handling of
Device0. For all other logs where the device numbe
