firmware: qcom: scm: Register gunyah watchdog device

2026-03-30T14:10:24Z

To restrict Gunyah watchdog initialization to Qualcomm platforms running under the Gunyah Hypervisor, register the watchdog device in the QCOM SCM driver. When Gunyah is not present or Gunyah emulates MMIO-based watchdog, we expect Qualcomm watchdog or ARM SBSA watchdog device to be present in the devicetree. First, we make sure we're running under the Gunyah Hypervisor. Then we move to check if any of the above mentioned watchdog device nodes are present, if not then we proceed to register the SMC-based Gunyah watchdog device.

qcuefi_acquire() and qcuefi_release() end with mutex locked or unlocked respectively, so annotate them so the lock usage will be tracked by context tracking tools. Note that mutex is tracked since commit 370f0a345a70 ("locking/mutex: Support Clang's context analysis").
