PSCI: Add pwr_domain_pwr_down_wfi() hook in plat_psci_ops
This patch adds a new optional platform hook `pwr_domain_pwr_down_wfi()` in the plat_psci_ops structure. This hook allows the platform to perform platform specific actions including the wfi invocation to enter powerdown. This hook is invoked by both psci_do_cpu_off() and psci_cpu_suspend_start() functions. The porting-guide.md is also updated for the same. This patch also modifies the `psci_power_down_wfi()` function to invoke `plat_panic_handler` incase of panic instead of the busy while loop. Fixes ARM-Software/tf-issues#375 Change-Id: Iba104469a1445ee8d59fb3a6fdd0a98e7f24dfa3 |
