The RSC interrupt is issued only after the request is complete. For
fire-n-forget requests, the irq-done interrupt is sent after issuing the
RPMH request and for response-required request, the interrupt is
triggered only after all the requests are complete.

These unnecessary checks in the interrupt handler issues AHB reads from
a critical path. Lets remove them and clean up error handling in

The next wakeup timer value needs to be set in always on domain timer
as the arch timer interrupt can not wakeup the SoC if after the deepest
CPUidle states the SoC also enters deepest low power state.

To wakeup the SoC in such scenarios the earliest wakeup time is set in
CONTROL_TCS and the firmware takes care of setting up its own timer in
always on domain with next wakeup time. The timer wakes up the RSC and
sets resources back to wake state.

Lina Iyer 25092e6100 soc: qcom: rpmh-rsc: Attach RSC to cluster PM domain
RSC is part the CPU subsystem and powers off the CPU domains when all
the CPUs and no RPMH transactions are pending from any of the drivers.
The RSC needs to flush the 'sleep' and 'wake' votes that are critical
for saving power when all the CPUs are in idle.

Let's make RSC part of the CPU PM domains, by attaching it to the
cluster power domain. Registering for PM domain notifications, RSC
driver can be notified that the last CPU is powering down. When the last
CPU is powering down the domain, let's flush the 'sleep' and 'wake'
votes that are stored in the data buffers into the hardware and also
write next wakeup in CONTROL_TCS.

Bjorn Andersson 3a39049f88 soc: qcom: rpmhpd: Use highest corner until sync_state
In some cases the hardware that the bootloader has left configured
depends on RPMH power domains for their operation up until the point
where the related Linux device driver probes and can inherit that
configuration, or power down the hardware gracefully.

Unfortunately as Linux probes the releavant drivers in sequence there
are periods during the Linux boot flow where either the genpd refcount
will reach 0, or worse where the active performance_state votes does not
meet the requirements of the state that the hardware was left in.

One specific example of this is during boot of e.g. SM8150/SC8180X,
where the display clock controller probes, without any particular
performance state needs (to access its registers). This will drop the
MMCX rail to MIN_SVS, which isn't sufficient to sustain the clock rates
that the later probing MDP is configured to. This results in an
unrecoverable system state.

Handle both these cases by keeping the RPMH power-domais that are
referenced voted for highest state, until sync_state indicates that all
devices referencing the RPMH power-domain driver has been probed.

Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members, instead. So, replace zero-length arrays
declarations in anonymous union with the new DECLARE_FLEX_ARRAY()
helper macro.

This helper allows for flexible-array members in unions.

Manivannan Sadhasivam c13d7d261e soc: qcom: llcc: Pass LLCC version based register offsets to EDAC driver
The LLCC EDAC register offsets varies between each SoCs. Until now, the
EDAC driver used the hardcoded register offsets. But this caused crash
on SM8450 SoC where the register offsets has been changed.

So to avoid this crash and also to make it easy to accommodate changes for
new SoCs, let's pass the LLCC version specific register offsets to the
EDAC driver.

Currently, two set of offsets are used. One is starting from LLCC version
v1.0.0 used by all SoCs other than SM8450. For SM8450, LLCC version
starting from v2.1.0 is used.

Manivannan Sadhasivam 5365cea199 soc: qcom: llcc: Rename reg_offset structs to reflect LLCC version
The register offsets used by the LLCC block retains its layout for multiple
versions. For instance, starting from version v1.0.0 to v2.0.1 the offsets
are same. And starting from v2.1.0, the offsets changed.

But the current reg_offset naming convention is confusing. So to reflect
this change correctly in driver, let's encode the start version from which
the offsets got changed in reg_offset struct name. This will be
llcc_v1_reg_offset for v1.0.0 and llcc_v2_1_reg_offset for v2.1.0.
This will allow multiple SoCs to use the same reg_offset clearly.

And in the future if the offsets got changed again, then that specific
version could be encoded in the struct name.

Currently all usage of struct qmi_elem_info, which is used to define
the QMI message encoding/decoding rules, does not use const. This
prevents clients from registering const arrays. Since these arrays are
always pre-defined, they should be const, so add the const qualifier
to all places in the QMI interface where struct qmi_elem_info is used.

Once this patch is in place, clients can independently update their
pre-defined arrays to be const, as demonstrated in the QMI sample
code.

Refactor the code to prepare it for supporting BWMON v5 which comes with
different register layout by:
1. Adding use of MMIO regmap and regmap fields which allows to keep one
   code logic with different register maps.
2. The "clear" type registers do not allow reading, therefore regmap
   requires using cache with default values.
3. regmap has an effect of introducing barriers after each readl/writel,
   which should negligible effect as only few writes were relaxed.
4. Additionally usage of regmap fields removes need of shifting the
   register values.
5. Add "V4" prefix to names of all defines with register addresses (so
   BWMON_V4_xxx) to differentiate it from V5.  The actual register values
   are shared so keep their naming.
6. While changing the defines, pad register addresses to three digits
   for readability.
