This introduces a new API for the BPMP to be pass along a specifier from
DT when getting a reference from a phandle. This is used to reference
specific instances of the PCI controller on Tegra264. The ABI header for
BPMP is updated to the latest version and BPMP APIs now use the more

Highlights:
----------
Stm32 SoCs embed debug peripherals such as Coresight. These peripherals
can monitor the activity of the cores. Because of that, they can be
used only if some features in the debug configuration are enabled.
Else, errors or firewall exceptions can be observed. Similarly to
the ETZPC(on stm32mp1x platforms) or the RIFSC(on stm32mp2x platforms),
debug-related peripherals access can be assessed at bus level to
prevent these issues from happening.
The debug configuration can only be accessed by the secure world.
That means that a service must be implemented in the secure world for
the kernel to check the firewall configuration. On OpenSTLinux, it is
done through a Debug access PTA in OP-TEE [1].
To represent the debug peripherals present on a dedicated debug bus,
create a debug bus node in the device tree and the associated driver
that will interact with this PTA.
Plus some fixes.

This batch mainly improves SCMI robustness on systems where the SCP does
not generate completion interrupts, and includes two small follow-up
cleanups in the SCMI core.
The main functional change adds support for the new DT property
'arm,no-completion-irq'. When present for mailbox/shared-memory based
SCMI implementations, the driver forces SCMI operations into polling
mode so affected platforms can continue to operate even with broken
firmware interrupt behavior.
In addition, it
- replaces open-coded size rounding in the base protocol path with
round_up() for clarity, with no functional change
- updates the SCMI quirk snippet macro implementation so quirk handlers
can use break and continue directly when invoked inside loop contexts

Populate the IO pads and pins for Tegra264. Tegra264 has internal 1.8V
and 0.6V regulators that must be enabled when selecting the 1.8V mode
for the sdmmc1-hv IO pad. To support this a new 'ena_1v8' member is
added to the 'tegra_io_pad_vctrl' structure to populate the bits that
need to be set to enable these internal regulators. Although this is
enabling 1.8V (bit 1) and 0.6V (bit 2) regulators, it is simply called
'ena_1v8' because these are both enabled for 1.8V operation. Note that
these internal regulators are disabled when not using 1.8V mode.

indicate that the SoC supports the write-enable register.

For Tegra devices, only a subset of IO pads can be configured for 1.8V
or 3.3V. Therefore, in the 'tegra_io_pad_soc' structure for Tegra SoCs
either all or most of the 'voltage' entries are set to UINT_MAX to
indicate the IO pad voltage cannot be configured. So for the majority of
IO pads this configuration is not applicable. However, refactoring the
IO pad data to move this parameter into a separate structure does not
make sense because the benefits are marginal.
Support for the Tegra264 IO pads is currently missing and the control
for configuring the voltage for the IO pads for Tegra264 has changed.
Instead of having a single register that is used for setting the IO pad
voltage for all IO pads, there is now a register associated with the
specific IO pad. For Tegra264, there is now only one IO pad that can be
configured for 1.8V or 3.3V which is the sdmmc1-hv. While we could make
this work with by adding a new SoC flag, the implementation will be a
bit cumbersome. Therefore, it now seems reasonable to refactor the IO
pad code. Hence, introduce a new 'tegra_io_pad_vctrl' structure that
contains the register offset and bit for enabling/disabling 3.3V mode
and move the existing voltage control data for supported SoCs to this
structure. This has an added benefit of simplifying the code in the
functions tegra_io_pad_get_voltage and tegra_io_pad_set_voltage.

Each SCMI firmware quirk contains a code snippet, which handles the
quirk, and has full access to the surrounding context. When this
context is (part of) a loop body, the code snippet may want to use loop
control statements like "break" and "continue". Unfortunately the
SCMI_QUIRK() macro implementation contains a dummy loop, taking
precedence over any outer loops. Hence quirk code cannot use loop
control statements, but has to resort to polluting the surrounding
context with a label, and use goto.
Fix this by replacing the "do { ... } while (0)" construct in the
SCMI_QUIRK() implementation by "({ ... })".
