10d3e5d20b firmware: scmi: fix sandbox and related tests for clock discovery
Updates sandbox SCMI clock driver and tests since enabling CCF will
mandate clock discovery that is all exposed SCMI clocks shall be
discovered at initialization. For this reason, sandbox SCMI clock
driver must emulate all clocks exposed by SCMI server, not only those
effectively consumed by some other U-Boot devices.

Therefore the sandbox SCMI test driver exposes 3 clocks (IDs 0, 1 and 2)
and sandbox SCMI clock consumer driver gets 2 of them.

6983710a31 scmi: change parameter dev in devm_scmi_process_msg
Changes devm_scmi_process_msg() first argument from target parent device
to current SCMI device and lookup the SCMI agent device among SCMI device
parents for find the SCMI agent operator needed for communication with
the firmware.

This change is needed in order to support CCF in clk_scmi driver unless
what CCF will fail to find the right udevice related to exposed SCMI
clocks.

This patch allows to simplify the caller sequence, using SCMI device
reference as parameter instead of knowing SCMI uclass topology. This
change also adds some protection in case devm_scmi_process_msg() API
function is called for an invalid device type.

41d62e2f27 sandbox: scmi: test against a single scmi agent
As per DT bindings since Linux kernel v5.14, the device tree can define
only 1 SCMI agent node that is named scmi [1]. As a consequence, change
implementation of the SCMI driver test through sandbox architecture to

This change updates sandbox test DT and sandbox SCMI driver accordingly
since all these are impacted.

e0283cbdfd power: zynqmp: Add power domain driver for ZynqMP
Driver should be enabled by CONFIG_POWER_DOMAIN=y and
CONFIG_ZYNQMP_POWER_DOMAIN=y. Power domain driver doesn't have own DT node
but it uses zynqmp firmware DT node that's why there is a need to bind
driver when firmware node is found.

Driver itself is simple. It is sending pmufw config object overlay for
enabling access to device which is done in ...domain_request().
In ...domain_on() capabilities are passed and node is requested.
This should be bare minimum of required to get power domain driver working.

Power domain driver sends PM fragment to PMUFW. It is sent for every node
which is listed in DT. But some nodes could be already enabled but driver
is not capable to find it out. That's why it blinly sents request for every

there is no need to show any error message because node is already enabled.

48108f3a6a firmware: scmi: Add OP-TEE transport
This change implements an SCMI transport for agent interfacing the
OP-TEE SCMI service. OP-TEE provides an SCMI PTA (Pseudo-TA) for
non-secure world to send SCMI messages over an identified channel.
The driver implemented here uses a SMT shared memory for passing
messages between client and server.

The implementation opens and releases channel resources for each
passed SCMI message so that resources allocated (sessions) or
registered (shared memory areas) in OP-TEE firmware are released for
example before relocation as the driver will likely allocate/register
them back when probed after relocation.

The integration of the driver using dedicated config switch
CONFIG_SCMI_AGENT_OPTEE is designed on the model posted to the
U-Boot ML by Patrick Delaunay [1].

5d5a699855 firmware: ti_sci: Add support for Resoure Management at R5 SPL stage.
On J721e and J7200, MCU R5 core (boot master) itself would run Device
Manager (DM) Firmware and interact with TI Foundational Security (TIFS)
firmware to enable DMA and such other Resource Management (RM) services.
So, during R5 SPL stage there is no such RM service available and ti_sci
driver will have to directly interact with TIFS using DM to DMSC
channels to request RM resources.

Therefore add DT binding and driver for the same. This driver will
handle Resource Management services at R5 SPL stage.

In case of R5 SPL, GET_RANGE API service is not available (as DM
services are not yet up), therefore service such calls locally using

236f2ec432 treewide: Convert macro and uses of __section(foo) to __section("foo")
This commit does the same thing as Linux commit 33def8498fdd.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.

Remove the quote operator # from compiler_attributes.h __section macro.

Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

feb7ac457c dm: core: Add address translation in fdt_get_resource
Today of_address_to_resource() is called only in
ofnode_read_resource() for livetree support and
fdt_get_resource() is called when livetree is not supported.

The fdt_get_resource() doesn't do the address translation
so when it is required, but the address translation is done
by ofnode_read_resource() caller, for example in
drivers/firmware/scmi/smt.c::scmi_dt_get_smt_buffer() {
...
	ret = ofnode_read_resource(args.node, 0, &resource);
	if (ret)
		return ret;

	faddr = cpu_to_fdt32(resource.start);
	paddr = ofnode_translate_address(args.node, &faddr);
...

The both behavior should be aligned and the address translation
must be called in fdt_get_resource() and removed for each caller.

b7135b034f psci: add features/reset2 support
Adds support for:
* PSCI_FEATURES, which was introduced in PSCI 1.0. This provides API
that allows discovering whether a specific PSCI function is implemented
and its features.
* SYSTEM_RESET2, which was introduced in PSCI 1.1, which extends existing
SYSTEM_RESET. It provides support for vendor-specific resets, providing
reset_type as an additional param.

For additional details visit [1].

Implementations of some functions were borrowed from Linux PSCI driver
code [2].

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.
