a65a4ea156 soc/tegra: fuse: Clear fuse->clk on driver probe failure
The fuse->clk must be cleared if FUSE driver fails to probe, otherwise
tegra_fuse_readl() will crash. It's unlikely to happen in practice,
nevertheless let's correct it for completeness.

9c93ccfc86 soc/tegra: pmc: Prevent racing with cpuilde driver
Both PMC and cpuidle drivers are probed at the same init level and
cpuidle depends on the PMC suspend mode. Add new default suspend mode
that indicates whether PMC driver has been probed and reset the mode in
a case of deferred probe of the PMC driver.

ed4520d6a1 soc: ti: Remove pm_runtime_irq_safe() usage for smartreflex
For the smartreflex device, we need to disable smartreflex on SoC idle,
and have been using pm_runtime_irq_safe() to do that. But we want to
remove the irq_safe usage as PM runtime takes a permanent usage count
on the parent device with it.

In order to remove the need for pm_runtime_irq_safe(), let's gate
the clock directly in the driver. This removes the need to call PM runtime
during idle, and allows us to switch to using CPU_PM in the following
patch.

Note that the smartreflex interconnect target module is configured for smart
idle, but the clock does not have autoidle capability, and needs to be gated
manually. If the clock supported autoidle, we would not need to even gate
the clock.

With this change, we can now remove the related quirk flags for ti-sysc
also.

22ea87ef3f soc: ti: pruss: Enable support for ICSSG subsystems on K3 AM64x SoCs
The K3 AM64x family of SoCs have a similar version of the PRU-ICSS (ICSSG)
processor subsystem present on K3 J721E and K3 AM65x SR2.0 SoCs. These SoCs
contain typically two ICSSG instances named ICSSG0 and ICSSG1. The two
ICSSGs are identical to each other for the most part with minor SoC
integration differences and capabilities. SGMII mode is not supported at
all on these SoCs (unlike specific instances on AM65x, J721E). The ICSSG1
also has limited pins connected on some sub-modules compared to ICSSG0.

There is no change in the Interrupt Controller w.r.t either of AM65x or
J721E SoCs. All other integration aspects are also very similar to the
existing SoCs.

The existing pruss platform driver has been updated to support these
similar ICSSG instances through a new AM64x specific compatible.

be7ecbd240 soc: fsl: qe: convert QE interrupt controller to platform_device
Since 5.13 QE's ucc nodes can't get interrupts from devicetree:

	ucc@2000 {
		cell-index = <1>;
		reg = <0x2000 0x200>;
		interrupts = <32>;
		interrupt-parent = <&qeic>;
	};

Now fw_devlink expects driver to create and probe a struct device
for interrupt controller.

So lets convert this driver to simple platform_device with probe().
Also use platform_get_ and devm_ family function to get/allocate
resources and drop unused .compatible = "qeic".

e3d4571955 soc: qcom: smsm: Fix missed interrupts if state changes while masked
The SMSM driver detects interrupt edges by tracking the last state
it has seen (and has triggered the interrupt handler for). This works
fine, but only if the interrupt does not change state while masked.

For example, if an interrupt is unmasked while the state is HIGH,
the stored last_value for that interrupt might still be LOW. Then,
when the remote processor triggers smsm_intr() we assume that nothing
has changed, even though the state might have changed from HIGH to LOW.

Attempt to fix this by checking the current remote state before
unmasking an IRQ. Use atomic operations to avoid the interrupt handler
from interfering with the unmask function.

This fixes modem crashes in some edge cases with the BAM-DMUX driver.
Specifically, the BAM-DMUX interrupt handler is not called for the
HIGH -> LOW smsm state transition if the BAM-DMUX driver is loaded
(and therefore unmasks the interrupt) after the modem was already started:

fc7a6209d5 bus: Make remove callback return void
The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.

This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.

With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

a89f355e46 soc: qcom: aoss: Fix the out of bound usage of cooling_devs
In "qmp_cooling_devices_register", the count value is initially
QMP_NUM_COOLING_RESOURCES, which is 2. Based on the initial count value,
the memory for cooling_devs is allocated. Then while calling the
"qmp_cooling_device_add" function, count value is post-incremented for
each child node.

This makes the out of bound access to the cooling_dev array. Fix it by
passing the QMP_NUM_COOLING_RESOURCES definition to devm_kzalloc() and
initializing the count to 0.

While at it, let's also free the memory allocated to cooling_dev if no
cooling device is found in DT and during unroll phase.

d43b3a989b soc: qcom: rpmhpd: Use corner in power_off
rpmhpd_aggregate_corner() takes a corner as parameter, but in
rpmhpd_power_off() the code requests the level of the first corner
instead.

In all (known) current cases the first corner has level 0, so this
change should be a nop, but in case that there's a power domain with a
non-zero lowest level this makes sure that rpmhpd_power_off() actually
requests the lowest level - which is the closest to "power off" we can
get.

While touching the code, also skip the unnecessary zero-initialization
of "ret".

Pull clk updates from Stephen Boyd:
 "This round has a diffstat dominated by Qualcomm clk drivers. Honestly
  though that's just a bunch of data so the diffstat reflects that.
  Looking beyond that there's just a bunch of updates all around in
  various clk drivers. Renesas and NXP (for i.MX) are two SoC vendors
  that have a lot of patches in here.

  Overall the driver changes look to be mostly enabling more clks and
  non-critical fixes that we could hold until the next merge window.

  I'm especially excited about the series from Arnd that graduates
  clkdev to be the only implementation of clk_get() and clk_put().
  That's a good step in the right direction to migreate eveerything over
  to the common clk framework. Now we don't have to worry about clkdev
  specific details, they're just part of the clk API now.

  Core:
   - clkdev is now the only option, i.e. clk_get()/clk_put() is
     implemented in only one place in the kernel instead of in
     drivers/clk/clkdev.c and in architectures that want their own
     implementation

There are several purposes of doing this:
- dropping dependency in bug.h
- dropping a loop by moving out panic_notifier.h
- unload kernel.h from something which has its own domain

At the same time convert users tree-wide to use new headers, although for
the time being include new header back to kernel.h to avoid twisted
indirected includes for existing users.

This is a major chunk of IXP4xx modernization:

- Fist we move some registers around to make room for
  the predetermined PCI I/O space.

- Then we add some Kconfig options to make it possible
  to use the old PCI driver in parallell with the new
  shiny one.

- Then we add the new PCI driver and some bindings for
  it.

- On top of this we add an (ages old) patch from Arnd
  that centralize the CPU/SoC detection in drivers/soc
  and make the header a standard Linux header to avoid
  the <mach/*> business in drivers.

- Then we split out and modernize some platform data
  headers for pata, and hwrandom, and top it up with
  DT bindings and support for hwrandom.

Memory controller drivers for v5.14 - Tegra SoC, part two

Second set of changes for Tegra SoC memory controller drivers,
containing patchset from Thierry Reding:

"The goal here is to avoid early identity mappings altogether and instead
postpone the need for the identity mappings to when devices are attached
to the SMMU. This works by making the SMMU driver coordinate with the
memory controller driver on when to start enforcing SMMU translations.
This makes Tegra behave in a more standard way and pushes the code to
deal with the Tegra-specific programming into the NVIDIA SMMU
implementation."

This pulls a dependency from Will Deacon (ARM SMMU driver) and contains
further ARM SMMU driver patches to resolve complex dependencies between
different patchsets.  The pull from Will contains only one patch
("Implement ->probe_finalize()").  Further work in Will's tree might
depend on this patch, therefore patch was applied there.

On the other hand, this ("Implement ->probe_finalize()") patch is also a
dependency for ARM SMMU driver changes for Tegra.  These changes,
bringing seamless transition from the firmware framebuffer to the OS
framebuffer, depend on earlier Tegra memory controller driver patches.

d5d9f7ac58 ARM/ixp4xx: Make NEED_MACH_IO_H optional
In order to create a proper PCI driver for the IXP4xx
we need to make the old PCI driver and its reliance
on <mach/io.h> optional.

Create a new Kconfig symbol for the legacy PCI driver
IXP4XX_PCI_LEGACY and only activate NEED_MACH_IO_H
for this driver.

A few files need to be adjusted to explicitly include
the <mach/hardware.h> and <mach/cpu.h> headers that
they previously obtained implicitly using <linux/io.h>
that would include <mach/io.h> and in turn include
these two headers.

This breaks our reliance on the old PCI and indirect
PCI support so we can reimplement a proper purely
DT-based driver in the PCI subsystem.
