Merge tag 'firmware/psci-1.0' of git://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/linux into next/drivers
This pull request contains patches that enable PSCI 1.0 firmware
features for arm/arm64 platforms:
- Lorenzo Pieralisi adds support for the PSCI_FEATURES call, manages
various 1.0 specifications updates (power state id and functions return
values) and provides PSCI v1.0 DT bindings
- Sudeep Holla implements PSCI v1.0 system suspend support to enable PSCI
based suspend-to-RAM
* tag 'firmware/psci-1.0' of git://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/linux:
drivers: firmware: psci: add system suspend support
drivers: firmware: psci: define more generic PSCI_FN_NATIVE macro
drivers: firmware: psci: add PSCI v1.0 DT bindings
drivers: firmware: psci: add extended stateid power_state support
drivers: firmware: psci: add PSCI_FEATURES call
drivers: firmware: psci: move power_state handling to generic code
drivers: firmware: psci: add INVALID_ADDRESS return value
