The new prefix allows the GPIOs to be uniquely identified on a per-chip
basis, which makes it easier to distinguish Tegra186 specific GPIOs from
those of later chips such as Tegra194 which supports a very different

The RPMh power domain driver aggregates the corner votes from various
consumers for the ARC resources and communicates it to RPMh.
With RPMh we use 2 different numbering space for corners, one used
by the clients to express their performance needs, and another used
to communicate to RPMh hardware.
The clients express their performance requirements using a sparse
numbering space which are mapped to meaningful levels like RET, SVS,
NOMINAL, TURBO etc which then get mapped to another number space
between 0 and 15 which is communicated to RPMh. The sparse number space,
also referred to as vlvl is mapped to the continuous number space of 0
to 15, also referred to as hlvl, using command DB.
Some power domain clients could request a performance state only while
the CPU is active, while some others could request for a certain
performance state all the time regardless of the state of the CPU.
We handle this by internally aggregating the votes from both type of
clients and then send the aggregated votes to RPMh.
There are also 3 different types of votes that are comunicated to RPMh
for every resource.
1. ACTIVE_ONLY:
This specifies the requirement for the resource when the CPU is
active
2. SLEEP:
This specifies the requirement for the resource when the CPU is
going to sleep
3. WAKE_ONLY:
This specifies the requirement for the resource when the CPU is
coming out of sleep to active state
We add data for all power domains on sdm845 SoC as part of the patch.
The driver can be extended to support other SoCs which support RPMh

At the moment, the dpio-driver allocates an MC portal at probe time and
frees it right after usage. The same thing happens on the remove path.
This behavior could lead to scenarios where an MC portal is available
for use at probing but not longer free on the remove path which could
lead to unproper unbind of resources.
Change the driver's behavior in such a way that an MC portal is
allocated at probe and kept until the DPIO device is removed. This will
ensure that at any time after a DPIO device was successfully probed, all
its dependencies will be met.

with the following warning:
drivers/soc/fsl/qe/qe_tdm.c:177:21-24: ERROR: pdev is NULL but dereferenced.
2, dev gets modified, so in any case that devm_iounmap() will fail
even when the new pdev is valid, because the iomap was done with a
different pdev.
3, there is no driver bind with the "fsl,t1040-qe-si" or

with these devices won't provide a cleanup path for these resources

To control power to a power domain, the System Controller (SYSC) needs
the corresponding interrupt source to be enabled, but masked, to prevent
the CPU from receiving it.
Currently this is handled in the driver's probe() routine, and set up
for every domain present, even if it will not be controlled directly by
SYSC (CPU domains are powered through the APMU on R-Car Gen2 and later).
On R-Car Gen3, PSCI powers down the SoC during system suspend, thus
losing any configured interrupt state. Hence after system resume, power
domains not controlled through the APMU (e.g. A3IR, A3VC, A3VP) fail to
power up.
Fix this by replacing the global interrupt setup in the probe() routine
by a domain-specific interrupt setup in rcar_sysc_power(), where the
domain's power is actually controlled. This brings the code more in
line with the flowchart in the Hardware User's Manual.

Commit 977d5ba450 ("soc: renesas: rcar-sysc: Make PM domain
initialization more robust") split PM Domain registration and the
linking of children to their parents, to accommodate PM Domain tables
that list child domains before their parents.
However, this failed to realize that parent power domains must be
powered up before their children anyway, and that this thus must be
reflected by the order in the PM Domain tables.
Revert the split, as it did not help anyway.

Until commit 7e8a50df26 ("soc: renesas: rcar-sysc: Drop legacy
handling"), the rcar_sysc_power_{down,up}() helpers were public, as they
were called by the legacy (pre-DT) CPU power management code on R-Car H1
and R-Car Gen2 before.
As they are just one-line wrappers around rcar_sysc_power(), it makes
sense to just remove them.
This also avoids a bool/helper/bool conversion in rcar_sysc_power_cpu(),
where a bool is checked to call one of two helper functions, which
just call rcar_sysc_power() with hardcoded boolean values again.

The workaround for the wrong hierarchy of the 3DG-{A,B} power
domains on R-Car E3 ES1.0 corrected the parent domains.
However, the 3DG-{A,B} power domains were still initialized and powered
in the wrong order, causing 3DG operation to fail.
Fix this by changing the order in the table at runtime, when running on
an affected SoC.

Just like the A64 and H5, the H3 SoC uses the system control block
to enable the EMAC clock.
Add a variant structure definition for the H3 and use it over the A10
one. This will allow using the H3-specific binding for the syscon node
attached to the EMAC instead of the generic syscon binding.

Let's change the function signature to return the pointer to memory or
an error pointer on failure, and take an argument that lets us return
the size of the aux data read. This way we can remove the
cmd_db_read_aux_data_len() API entirely and also get rid of the memcpy
operation from cmd_db to the caller. Updating the only user of this code
shows that making this change allows us to remove a function and put the
lookup where the user is.

The cmd_db_get_header() function is a static local function that doesn't
need to copy anything from one place to another. Instead, it can just
point into the region by returning pointers to what we're looking for.
If we do that, we should mark what we're returning as const so that code
can't modify cmd-db without an obvious cast.

llcc_slice_getd can return a ERR_PTR code on failure. Add a IS_ERR_OR_NULL
check to subsequent API calls that use struct llcc_slice_desc to guard
against faults and to let the leaf drivers get away with safely using a
ERR_PTR() encoded "pointer" in the aftermath of a llcc_slice_getd error.

when the kernel inits a SE, its quite possible we have pending interrupts
from bootloaders which did not handle/clear them. So do this in kernel at
the SE init, to avoid some of it causing bad behavior, while at it also
club all the register writes needed to clear the se irqs into a function
to avoid repeating it over.

When the kernel is built with CONFIG_THUMB2_KERNEL we would set the
kernel's resume entry point to be a function that is already built as
Thumb-2 code while the boot agent doing the resume is in ARM mode, so
this does not work. There is a header label defined: cpu_resume_arm
which we can use to do the switching for us.

The Keystone QMSS driver is pretty damaged, in the sense that it
does things like this:
irq_set_affinity_hint(irq, to_cpumask(&cpu_map));
where cpu_map is a local variable. As we leave the function, this
will point to nowhere-land, and things will end-up badly.
Instead, let's use a proper cpumask that gets allocated, giving
the driver a chance to actually work with things like irqbalance
as well as have a hypothetical 64bit future.

The most noteworthy SoC driver changes this time include:
- The TEE subsystem gains an in-kernel interface to access the TEE
from device drivers.
- The reset controller subsystem gains a driver for the Qualcomm
Snapdragon 845 Power Domain Controller.
- The Xilinx Zynq platform now has a firmware interface for its
platform management unit. This contains a firmware "ioctl" interface
that was a little controversial at first, but the version we merged
solved that by not exposing arbitrary firmware calls to user space.
- The Amlogic Meson platform gains a "canvas" driver that is used
for video processing and shared between different high-level drivers.
The rest is more of the usual, mostly related to SoC specific power
management support and core drivers in drivers/soc:
- Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
features related to power and reset control.
- The Mediatek mt8183 and mt6765 SoC platforms gain support for
their respective power management chips.
- A new driver for NXP i.MX8, which need a firmware interface for
power management.
- The SCPI firmware interface now contains support estimating power
usage of performance states
- The NVIDIA Tegra "pmc" driver gains a few new features, in particular
a pinctrl interface for configuring the pads.
- Lots of small changes for Qualcomm, in particular the "smem"
device driver.
- Some cleanups for the TI OMAP series related to their sysc
controller.
Additional cleanups and bugfixes in SoC specific drivers include the
Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.
