git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into arm/drivers
soc/tegra: Changes for v5.16-rc1
This set consists of stub additions to enable compile testing for more
drivers, exposes the PMC's USB regmap on all SoC generations, removes a
state synchronization workaround that is no longer needed and adds an
error reporting driver that can help troubleshoot crashes.
To top it all off, an error handling path in the powergating code is
fixed and the devm_platform_ioremap_resource() function is used to
remove some boilerplate code.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes
Fixes for omaps for v5.15
Few regression fixes for omaps for the v5.15-rc cycle. There is a fix
for boot time hangs that can happen on some am335x devices that started
when the pruss devicetree nodes were added. The other fixes are less
critical:
- Fix compiler warning for sysc_init_soc() that got recently introduced
- Fix external abort for am335x pruss as otherwise some am335x will hang
- Use CLKDM_NOAUTO quirk also for dra7 dcan1
- Fix older NAND device node regression for omap3-sdp

already done in the below and above error handling paths of this function.

This adds a driver for the blk-ctrl blocks found in the i.MX8M* line of
SoCs. The blk-ctrl is a top-level peripheral located in the various *MIX
power domains and interacts with the GPC power controller to provide the
peripherals in the power domain access to the NoC and ensures that those
peripherals are properly reset when their respective power domain is
brought back to life.
Software needs to do different things to make the bus handshake happen
after the GPC *MIX domain is powered up and before it is powered down.
As the requirements are quite different between the various blk-ctrls
there is a callback function provided to hook in the proper sequence.
The peripheral domains are quite uniform, they handle the soft clock
enables and resets in the blk-ctrl address space and sequencing with the
upstream GPC power domains.

Our usage of runtime PM to control the hierarchy of power domains is
slightly unusual and means that powering up a domain may fail in early
system resume, as runtime PM is still disallowed at this stage.
However the system suspend/resume path takes care of powering down/up
the power domains in the order defined by the device parent/child and
power-domain provider/consumer hierarachy. So we can just runtime
resume all our power-domain devices to allow the power-up to work
properly in the resume path. System suspend will still disable all
domains as intended.

This reverts commit a77ebdd9f553. It turns out that the VPU domain has no
different requirements, even though the downstream ATF implementation seems
to suggest otherwise. Powering on the domain with the reset asserted works
fine. As the changed sequence has caused sporadic issues with the GPU
domains, just revert the change to go back to the working sequence.

Some board designs don't supply power to all of the power domains,
as they are not used anyways. In that case we must make sure to
not touch those power domains at all, as trying to power up a
domain that has no power supplied to it will obviously end in a
system crash. Allow to disable those domains via the standard DT

To bring up the MX8MM GPU domain, it is necessary to configure both
GPC_PGC_nCTRL(GPU_2D) and GPC_PGC_nCTRL(GPU_3D) registers. Without
this configuration, the system might hang on boot when bringing up
the GPU power domain. This is sporadically observed on multiple
disparate systems.
Add the GPU3D bit into MX8MM GPU domain pgc bitfield, so that both
GPC_PGC_nCTRL(GPU_2D) and GPC_PGC_nCTRL(GPU_3D) registers are
configured when bringing up the GPU domain. This fixes the sporadic
hang.

There is currently the MX8MM GPU domain, which is in fact a composite domain
for both GPU2D and GPU3D. To correctly configure this domain, it is necessary
to control both GPC_PGC_nCTRL(GPU_2D) and GPC_PGC_nCTRL(GPU_3D) at the same
time. This is currently not possible.
Turn the domain->pgc from value into bitfield and use for_each_set_bit() to
iterate over all bits set in domain->pgc when configuring GPC_PGC_nCTRL
register array. This way it is possible to configure all GPC_PGC_nCTRL
registers required in a particular domain.
This is a preparatory patch, no functional change.

Starting with v5.15-rc1, we may now see some am335x beaglebone black
device produce the following error on pruss probe:
Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0326000
This has started with the enabling of pruss for am335x in the dts files.
Turns out the is caused by the PRM reset handling not waiting for the
reset bit to clear. To fix the issue, let's always wait for the reset
bit to clear, even if there is a separate reset status register.
We attempted to fix a similar issue for dra7 iva with a udelay() in
commit effe89e40037 ("soc: ti: omap-prm: Fix occasional abort on reset
deassert for dra7 iva"). There is no longer a need for the udelay()
for dra7 iva reset either with the check added for reset bit clearing.

Qualcomm Generic Packet router aka GPR is the IPC mechanism found
in AudioReach next generation signal processing framework to perform
command and response messages between various processors.
GPR has concepts of static and dynamic port, all static services like
APM (Audio Processing Manager), PRM (Proxy resource manager) have
fixed port numbers where as dynamic services like graphs have dynamic
port numbers which are allocated at runtime. All GPR packet messages
will have source and destination domain and port along with opcode
and payload.

APR and other packet routers like GPR are pretty much same and
interact with other drivers in similar way.
Ex: GPR ports can be considered as APR services, only difference
is they are allocated dynamically.
Other difference is packet layout, which should not matter
with the apis abstracted. Apart from this the rest of the
functionality is pretty much identical across APR and GPR.
Make the apr code more reusable by abstracting it service level,
rather than device level so that we do not need to write
new drivers for other new packet routers like GPR.
This patch is in preparation to add GPR support to this driver.

Implement the support for SAW v4.1, used in at least MSM8998,
SDM630, SDM660 and APQ variants and, while at it, also add the
configuration for the SDM630/660 Silver and Gold cluster L2
Adaptive Voltage Scaler: this is also one of the prerequisites
to allow the OSM controller to perform DCVS.
Please note that despite there are various "versions" of these
values downstream, these are the only ones that are perfectly
stable on the entire set of tested devices.

In commit a871be6b8eee ("cpuidle: Convert Qualcomm SPM driver to a generic
CPUidle driver") the SPM driver has been converted to a
generic CPUidle driver: that was mainly made to simplify the
driver and that was a great accomplishment;
Though, at that time, this driver was only applicable to ARM 32-bit SoCs,
lacking logic about the handling of newer generation SAW.
In preparation for the enablement of SPM features on AArch64/ARM64,
split the cpuidle-qcom-spm driver in two: the CPUIdle related
state machine (currently used only on ARM SoCs) stays there, while
the SPM communication handling lands back in soc/qcom/spm.c and
also making sure to not discard the simplifications that were
introduced in the aforementioned commit.
Since now the "two drivers" are split, the SCM dependency in the
main SPM handling is gone and for this reason it was also possible
to move the SPM initialization early: this will also make sure that
whenever the SAW CPUIdle driver is getting initialized, the SPM
driver will be ready to do the job.
Please note that the anticipation of the SPM initialization was
also done to optimize the boot times on platforms that have their
CPU/L2 idle states managed by other means (such as PSCI), while
needing SAW initialization for other purposes, like AVS control.
