Qualcomm ARM64 DT updates for 5.11
For SM8250 the recently introduced support for handling boot-loader
stream mappings in the ARM SMMU allow us to enable this, and thereby USB
controller and PHY, SDHCI controller and FastRPC, as well as support for
the SM8250 HDK board has been added. Additionally PRNG and RTC is
enabled.
Similarly for SM8150, the ARM SMMU could be added which allows the
secondary USB controller and PHYs, as well as WiFi to be added and
support for the SM8150 HDK board to be introduced. Additionally
Coresight and support for the last-level cache controller was added.
MSM8916 finally has VDDCX and VDDMX removed as regulators and are now
handled by the rpmpd driver for the devices controlling them. The
Longsheer L8150 gains touchscreen, sensors, vibrator and LED support.
MSM8992 gains USB and SDHCI support as well as an I2C controller and the
associated RMI4 based touchscreen for the Lumia 950.
MSM8994 also gains USB and SDHCI support, as well as VADC and temp-alarm
support. Then support for the Lumia 950 XL is added.
SDM845 gains interconnect properties for a number of devices and the
GENI wrappers gains iommu stream configuration, which means DMA
operations on e.g. I2C now works. The Lenovo Yoga C630 finally has the
SMMU enabled, a few fixes and the description of the eDP bridge and
panel means that the laptop can now boot mainline with working display,
GPU, WiFi and audio.
SC7180 gains a slew of smaller improvements and fixes.

The following errors are noticed during boot on a QCS404 board:
[ 2.926647] qcom_icc_rpm_smd_send mas 6 error -6
[ 2.934573] qcom_icc_rpm_smd_send mas 8 error -6
These errors show when we try to configure the GPU and display nodes.
Since these particular nodes aren't supported on RPM and are purely
local, we should just change their mas_rpm_id to -1 to avoid any
requests being sent for these master IDs.

Some nodes are incorrectly marked as RPM-controlled (they have RPM
master and slave ids assigned), but are actually controlled by the
application CPU instead. The RPM complains when we send requests for
resources that it can't control. Let's fix this by replacing the IDs,
with the default "-1" in which case no requests are sent.

When sync_state support got introduced recently, by default we try to
set the NoCs to run initially at maximum rate. But as these values are
aggregated, we may end with a really big clock rate value, which is
then converted from "u64" to "long" during the clock rate rounding.
But on 32bit platforms this may result an overflow. Fix it by making
sure that the rate is within range.

In addition to the rest of Qcom interconnect drivers use icc_sync_state
for SM8150/SM8250 interconnect drivers to notify the interconnect
framework when all consumers are probed and there is no need to keep the
bandwidth set to maximum anymore.
Also move the BCM initialization before creating the nodes to set the
max bandwidth in hardware for the initialization/probing stage.

After enabling interconnect scaling for display on the db845c board,
in certain configurations the board hangs, while the following errors
are observed on the console:
Error sending AMC RPMH requests (-110)
qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000
qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000
qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000
...
In this specific case, the above is related to one of the sequencers
being stuck, while client drivers are returning from probe and trying
to disable the currently unused clock and interconnect resources.
Generally we want to keep the multimedia NoC enabled like the rest of
the NoCs, so let's set the keepalive flag on it too.

Lowering the bandwidth on the bus might have negative consequences if
it's done before all consumers had a chance to cast their vote. Now by
default the framework sets the bandwidth to maximum during boot. We need
to use the icc_sync_state callback to notify the framework when all
consumers are probed and there is no need to keep the bandwidth set to
maximum anymore.

Change the default TCS wait behavior to only wait for completion in AMC
and WAKE. Waiting isn't necessary in the SLEEP TCS, since votes are only
being removed in this case. Resources can be safely disabled
asynchronously in parallel with the rest of the power collapse sequence.
This reduces the sleep entry latency.

Currently, all bcm-voters set tcs_cmd::wait=true for the last VCD
command in each TCS (AMC, WAKE, and SLEEP). However, some bcm-voters
don't need the completion and instead need to optimize for latency. For
instance, disabling wait-for-completion in the WAKE set can decrease
resume latency and allow for certain operations to occur in parallel
with the WAKE TCS triggering. This is only safe in very specific
situations. Keep the default behavior of always waiting, but allow it to
be overridden in devicetree.

Pull ARM SoC driver updates from Arnd Bergmann:
"A couple of subsystems have their own subsystem maintainers but choose
to have the code merged through the soc tree as upstream, as the code
tends to be used across multiple SoCs or has SoC specific drivers
itself:
- memory controllers:
Krzysztof Kozlowski takes ownership of the drivers/memory subsystem
and its drivers, starting out with a set of cleanup patches.
A larger driver for the Tegra memory controller that was
accidentally missed for v5.8 is now added.
- reset controllers:
Only minor updates to drivers/reset this time
- firmware:
The "turris mox" firmware driver gains support for signed firmware
blobs The tegra firmware driver gets extended to export some debug
information Various updates to i.MX firmware drivers, mostly
cosmetic
- ARM SCMI/SCPI:
A new mechanism for platform notifications is added, among a number
of minor changes.
- optee:
Probing of the TEE bus is rewritten to better support detection of
devices that depend on the tee-supplicant user space. A new
firmware based trusted platform module (fTPM) driver is added based
on OP-TEE
- SoC attributes:
A new driver is added to provide a generic soc_device for
identifying a machine through the SMCCC ARCH_SOC_ID firmware
interface rather than by probing SoC family specific registers.
The series also contains some cleanups to the common soc_device
code.
There are also a number of updates to SoC specific drivers, the main
ones are:
- Mediatek cmdq driver gains a few in-kernel interfaces
- Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
support for additional SoC variants
- The Qualcomm GENI core code gains interconnect path voting and
performance level support, and integrating this into a number of
device drivers.
- A new driver for Samsung Exynos5800 voltage coupler for
- Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
specific device drivers
- Updates to the TI K3 Ring Accelerator driver"
