Purwa will crash if HLOS attempts to access or configure the TPM pins, as these operations require higher privilege levels. Therefore, the TPM pins should be reserved in the DTS until NHLOS provides proper support. Signed-off-by: Yijie Yang <yijie.yang@oss.qualcomm.com>
Document the compatible for the X1E80100 platform to the Qualcomm watchdog binding. The HW implementation is compatible with the KPSS WDT.

The watchdog support in EL1 is SBSA compliant, handled by Gunyah hypervisor, but in EL2. the watchdog is an instance of the APSS WDT HW block, same as older platforms. So describe the APSS WDT node and mark it as reserved, as it will only be enabled in EL2 overlay.

In EL2, the APSS watchdog is available. So enable it in the overlay.

Add support for building an EL2 combined DTB for the hamoa-evk in the Qualcomm DTS Makefile. The new hamoa-iot-evk-el2.dtb is generated by combining the base hamoa-iot-evk.dtb with the x1-el2.dtbo overlay, enabling EL2-specific configurations required by the platform.
