If APU is in suspending state and if wakeup request comes then
PMUFW returns error which is not handled at ATF side.
To fix this, get the APU node status before calling wakeup and
return error if found in suspending state.
Here, we can not handle the error code of pm_req_wakeup() from PMUFW
because ATF is already calling pm_client_wakeup() before calling
pm_req_wakeup().

This API returns version of supported APIs.
Here, there are three cases to check API version by using feature
check implementation.
1. Completely implemented in TF-A: I mean the EEMI APIs which are
completely implemented in the TF-A only. So check those IDs and
return appropriate version for the same. Right now, it is base
version.
2. Completely implemented in firmware: I mean the EEMI APIs which are
completely implemented in the firmware only. Here, TF-A only passes
Linux request to the firmware to get the version of supported API. So
check those IDs and send request to firmware to get the version and
return to Linux if the version is supported or return the error code
if the feature is not supported.
3. Partially implemented (Implemented in TF-A and firmware both):
First check dependent EEMI API version with the expected version in
the TF-A. If the dependent EEMI API is supported in firmware then
return its version and check with the expected version in the TF-A.
If the version matches then check for the actual requested EEMI API
version. If the version is supported then return version of API
implemented in TF-A.

This API will be used to set the PLL mode: reset (unlocked), integer
or fractional (locked). If reset mode is set the PM controller will
bypass the target PLL prior to asserting the reset. If integer or
fractional mode is set the PM controller will program and trigger
locking of the PLL. If success status is returned the PLL is locked
and its bypass is deasserted. If fractional mode is set the fractional
divider (data parameter) has to have a non-zero value prior to issuing
pll set fractional mode. The caller need to ensure that the data
parameter is properly set using pll get/set parameter EEMI API.

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.
The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.
The exceptions are files that are imported from other projects:
- CryptoCell driver
- dt-bindings folders
- zlib headers

ATF establishes a path to send the address of the structure
to the xilsecure, so that it will pick addresses of the data
and performs the requested operation (encrypt/decrypt) and puts
the result in load address.
where structure contains
- Data blob src address
- load address
- IV address
- Key address - this will actual key addr in case of KUP
else it will be zero.
- Data-size

psci system_reset and system_off calls now retrieve shutdown scope on
the fly. The default scope is system, but it can be changed by calling
pm_system_shutdown(2, scope)
Until full support for different restart scopes becomes available with
PSCI 1.1 this change allows users to set the reboot scope to match
their application needs.
Possible scope values:
0 - APU subsystem: does not affect RPU, PMU or PL
1 - PS only: shutdown/restart entire PS without affecting PL
2 - System: shutdown/restart applies to entire system

During system suspend, identify slaves which are configured
as wake sources and call pm_set_wakeup_source API for each of them.
Identifying if device may wake the system is done by checking if any
interrupt of that device is enabled in GICD_ISENABLER when the APU is
about to enter SUSPEND_TO_RAM state. If such interrupt is found,
pm_set_wakeup_source is called with corresponding PM node ID as
argument.

which the APU intends to suspend. The state can be:

on
- PM_APU_STATE_SUSPEND_TO_RAM - all processors powered down, L2$
powered down, all OCM banks in retention and DDR in
self-refresh.
