Subject: [PATCH v1 0/5] hwmon: Add support for Altera SoCFPGA hardware monitoring

From: Muhammad Amirul Asyraf Mohamad Jamian <muhammad.amirul.asyraf.mohamad.jamian@...era.com>

This series introduces hardware monitoring support for Altera SoCFPGA
platforms (Stratix10, Agilex, N5X), enabling voltage and temperature
monitoring through the existing firmware secure service interface.

The SoCFPGA platforms provide sensor data through secure firmware calls.
This driver interfaces with the firmware service layer to expose voltage
and temperature readings via the standard hwmon sysfs interface, allowing
userspace tools to monitor system health.

The series includes:
- Device tree binding documentation for the new hwmon driver
- Extension to firmware service bindings for hwmon capability  
- Driver implementation using the firmware service layer
- Device tree enablement for Stratix10 and Agilex platforms

Notes:
This patch series is applied on Hardware Monitoring maintainer's tree:
https://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging.git/log/?h=hwmon-next

This changes is validated on:
    - Documentation/devicetree/bindings/hwmon/altr,socfpga-hwmon.yaml
    - Agilex and Stratix10 development boards
