Now, with all the plumbing in place to enable building scmi as a module
instead of built-in modules, let us enable the same.

In preparation to enable building SCMI as a single module, let us move
the SCMI protocol registration call into the driver. This enables us
to also add unregistration of the SCMI protocols.
The main reason for this is to keep it simple instead of maintaining
it as separate modules and dealing with all possible initcall races
and deferred probe handling. We can move it as separate modules if
needed in future.

We need to export both arm_smccc_1_1_get_conduit and arm_smccc_get_version
to allow several modules make use of them. Arm FFA, Arm SCMI and PTP
drivers are few drivers that are planning to use these functions.
Let us export them in preparation to add support for SCMI as module.

Should not register power domain that not owned by current
partition.
Alought power domains will not be registered when power on failure,
we have to let CPU waste more cycles.
Whether power on or owned check, both need communicate with SCU,
but with owned check, we no need to run more code path to save CPU
cycles.

On non-EFI systems, it wasn't possible to test the platform firmware
loader because it will have never set "checked_fw" during __init.
Instead, allow the test code to override this check. Additionally split
the declarations into a private symbol namespace so there is greater
enforcement of the symbol visibility.

scmi_mailbox is obtained from cinfo->transport_info and the first
call to mailbox_chan_free frees the channel and sets cinfo->transport_info
to NULL. Care is taken to check for non NULL smbox->chan but smbox can
itself be NULL. Fix it by checking for it without which, kernel crashes
with below NULL pointer dereference and eventually kernel panic.

In preparation for adding --orphan-handling=warn to more architectures,
disable -mbranch-protection, as EFI does not yet support it[1]. This was
noticed due to it producing unwanted .note.gnu.property sections (prefixed
with .init due to the objcopy build step).
However, we must also work around a bug in Clang where the section is
still emitted for code-less object files[2], so also remove the section
during the objcopy.

Eliminate all GOT entries in the decompressor binary, by forcing hidden
visibility for all symbol references, which informs the compiler that
such references will be resolved at link time without the need for
allocating GOT entries.
To ensure that no GOT entries will creep back in, add an assertion to
the decompressor linker script that will fire if the .got section has
a non-zero size.

- Make defines for bcm63xx-gate clks to use in DT
- Support BCM2711 SoC firmware clks
- Add HDMI clks for BCM2711 SoCs
- Add RTC related clks on Ingenic SoCs
- Support USB PHY clks on Ingenic SoCs
- Support gate clks on BCM6318 SoCs
- RMU and DMAC/GPIO clock support for Actions Semi S500 SoCs
- Use poll_timeout functions in Rockchip clk driver
- Support Rockchip rk3288w SoC variant
- Mark mac_lbtest critical on Rockchip rk3188
- Add CAAM clock support for i.MX vf610 driver
- Add MU root clock support for i.MX imx8mp driver
- Amlogic g12: add neural network accelerator clock sources
- Amlogic meson8: remove critical flag for main PLL divider

Pull sched/fifo updates from Ingo Molnar:
"This adds the sched_set_fifo*() encapsulation APIs to remove static
priority level knowledge from non-scheduler code.
The three APIs for non-scheduler code to set SCHED_FIFO are:
- sched_set_fifo()
- sched_set_fifo_low()
- sched_set_normal()
These are two FIFO priority levels: default (high), and a 'low'
priority level, plus sched_set_normal() to set the policy back to
non-SCHED_FIFO.
Since the changes affect a lot of non-scheduler code, we kept this in
a separate tree"

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

Add support for the Inline Crypto Engine (ICE) key programming interface
that's needed for the ufs-qcom driver to use inline encryption on
Snapdragon SoCs. This interface consists of two SCM calls: one to program
a key into a keyslot, and one to invalidate a keyslot.
Although the UFS specification defines a standard way to do this, on these
SoCs the Linux kernel isn't permitted to access the needed crypto
configuration registers directly; these SCM calls must be used instead.

Qualcomm driver updates for v5.9
For RPMh this fixes an issue where ktime was used during suspend, allows
the driver to be used on ARM targets and some minor cleanups.
It adds support for the latest format version in the socinfo driver and
adds identifiers for SM8250 and SDM630.
SMD-RPM gains compatibles for MSM8994 and MSM8936 and the Qualcomm SCM
gains compatibles MSM8994 and IPQ8074.
The GENI core code gains interconnect path voting and performance level
support, with subsequent patches integrating this with the SPI, I2C,
UART and QSPI drivers.
Following this the KGDB support for the GENI serial driver is improved,
the performance related to chip-select is improved for SPI and QSPI.

The firmware on Turris MOX secure processor offers signing messages
with ECDSA private key stored in protected OTP memory.
The optimal solution would be to register an akcipher provider via
kernel's crypto API, but crypto API does not yet support accessing
akcipher API from userspace (and probably won't for some time, see
https://www.spinics.net/lists/linux-crypto/msg38388.html).
At first I tried to put this via standard sysfs API, but the way I
designed it is not compatible with sysfs's standard "one file per
attribute".
This patch therefore adds support for accessing this signature
generation mechanism via debugfs. Since CZ.NIC's Turris MOX is the only
user of this module, the potential future change to akcipher API should
not cause problems, since we can just change our userspace software then.

"A batch of arm64 fixes.
Although the diffstat is a bit larger than we'd usually have at this
stage, a decent amount of it is the addition of comments describing
our syscall tracing behaviour, and also a sweep across all the modular
arm64 PMU drivers to make them rebust against unloading and unbinding.
There are a couple of minor things kicking around at the moment (CPU
errata and module PLTs for very large modules), but I'm not expecting
any significant changes now for us in 5.8.
- Fix kernel text addresses for relocatable images booting using EFI
and with KASLR disabled so that they match the vmlinux ELF binary.
- Fix unloading and unbinding of PMU driver modules.
- Fix generic mmiowb() when writeX() is called from preemptible
context (reported by the riscv folks).
- Fix ptrace hardware single-step interactions with signal handlers,
system calls and reverse debugging.
