The patch be7ecbd240b2: "soc: fsl: qe: convert QE interrupt
controller to platform_device" from Aug 3, 2021, leads to the
following static checker warning:
drivers/soc/fsl/qe/qe_ic.c:438 qe_ic_init()
warn: unsigned 'qe_ic->virq_low' is never less than zero.
In old variant irq_of_parse_and_map() returns zero if failed so
unsigned int for virq_high/virq_low was ok.
In new variant platform_get_irq() returns negative error codes
if failed so we need to use int for virq_high/virq_low.
Also simplify high_handler checking and remove the curly braces
to make checkpatch happy.

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".

Use __raw_readl() here for consistency with the rest of the file.
This should really get converted to some proper accessor, as the
__raw functions are not meant to be used in drivers, but the driver
has used these since the start, so for the moment, let's only fix
the warning.

i.MX fixes for 5.14:
- A couple of fixes on MMDC driver to add missing iounmap() and
clk_disable_unprepare(), and a follow-up fix.
- Fix missing-prototypes warning in SRC driver.
- Revert commit 7d981405d0fd ("soc: imx8m: change to use platform
driver"), which breaks i.MX8M system that has CAAM driver enabled.
- One fix on imx53-m53menlo pinctrl configuration.
- Increase the PHY reset duration for imx6qdl-sr-som to fix intermittent
issues where the PHY would be unresponsive every once in a while.
- Add missing flag for in-band signalling between PHY and MAC on
kontron-sl28-var2 board to fix network support.
- Limit the SDIO Clock on Colibri iMX6ULL to 25MHz for fixing wireless
noise issue.
- Fix sysclk node name for LS1028A so that U-Boot is able to update the
"clock-frequency" property.

resulting compile test failures by removing the #include statements
that prevent building on most other platforms.

With the SoC matching changed to a platform driver the match data
is available only after other drivers, which may rely on it are
already probed. This breaks at least the CAAM driver on i.MX8M.
Revert the change until all those drivers have been audited and
changed to be able to eal with match data being available later
in the boot process.

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
New Drivers:
- Texas Instruments' LMK04832 Ultra Low-Noise JESD204B Compliant
Clock Jitter Cleaner With Dual Loop PLLs
- Qualcomm MDM9607 GCC
- Qualcomm SC8180X display clks
- Qualcomm SM6125 GCC
- Qualcomm SM8250 CAMCC (camera)
- Renesas RZ/G2L SoC
- Hisilicon hi3559A SoC

- Improve clock support for Actions S500 SoC
- duty cycle setting support on qcom clks
- Add TI am33xx spread spectrum clock support

kernel.h is being used as a dump for all kinds of stuff for a long time.
Here is the attempt to start cleaning it up by splitting out panic and
oops helpers.
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.

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.

In this new power domain driver, when adding one power domain
it will prepare the dependent clocks at the same.
So we only do clk_bulk_enable/disable control during power ON/OFF.
When system suspend, the pm runtime framework will forcely power off
power domains. However, the dependent clocks are disabled but kept
prepared.
In MediaTek clock drivers, PLL would be turned ON when we do
clk_bulk_prepare control.
Clock hierarchy:
PLL -->
DIV_CK -->
CLK_MUX
(may be dependent clocks)
-->
SUBSYS_CG
(may be dependent clocks)
It will lead some unexpected clock states during system suspend.
This patch will fix by doing prepare_enable/disable_unprepare on
dependent clocks at the same time while we are going to power on/off
any power domain.

Mediatek requires mmsys clocks to be unprepared during suspend,
otherwise system has chances to hang.
syscon_regmap_lookup_by_phandle_optional() will attach and prepare the
first clock in smi node, leading to additional prepare to the clock
which is not balanced with the prepare/unprepare pair in resume/suspend
callbacks.
If a power domain node requests an smi node and the smi node's first
clock is an mmsys clock, it will results in an unstable suspend resume.

Add driver state syncing that is invoked once all PMC consumers are
attached and ready. The consumers are the power domain clients.
The synchronization callback is invoked once all client drivers are
probed, the driver core handles this for us. This callback informs
PMC driver that all voltage votes are initialized by each PD client
and it's safe to begin voltage scaling of the core power domain.

NVIDIA Tegra SoCs have multiple power domains, each domain corresponds
to an external SoC power rail. Core power domain covers vast majority of
hardware blocks within a Tegra SoC. The voltage of a power domain should
be set to a level which satisfies all devices within the power domain.
Add support for the core power domain which controls voltage state of the
domain. This allows us to support system-wide DVFS on Tegra20-210 SoCs.
The PMC powergate domains now are sub-domains of the core domain, this
requires device-tree updating, older DTBs are unaffected and will continue
to work as before.
