Girisha Dengi	62dbe72cb7	drivers: pm_cpu_ops: Add support for multiple PSCI versions Each PSCI interface versions have different DT compatible strings like arm,psci-0.2, arm,psci-1.1 and so on. However, the same driver can be used for all the versions by adding #define DT_COMPAT for required version and #undef DT_COMPAT for default version. Add support for PSCI cold reset, warm reset and cpu-on function IDs.

Gerard Marull-Paretas	fb60aab245	drivers: migrate includes to <zephyr/...> In order to bring consistency in-tree, migrate all drivers to the new prefix <zephyr/...>. Note that the conversion has been scripted, refer to #45388 for more details. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>	3 years ago
Carlo Caione	0f9406277d	aarch64: pm_cpu_ops: Introduce pm_cpu_ops subsystem AArch64 has support for PSCI. This is especially useful for SMP because PSCI is used to power on the secordary cores. When the PSCI driver was introduced in Zephyr it was designed to rely on a very PSCI-centric subsystem / interface. There are two kinds of problems with this choice: 1. PSCI is only defined for the non-secure world and it is designed to boot CPU cores into non-secure state (that means that PSCI is only supposed to work if Zephyr is running in non-secure state) 2. There can be other ways or standards used to start / stop a core different from PSCI This patch is trying to fix the original wrong assumption by making the interface / subsystem a generic one, called 'pm_cpu_ops', and using PSCI only as an actual driver that is a user of this new interface / subsystem. For now the new subsystem is only exposing two methods: cpu_on and cpu_off, others will probably follow according to the needs. Signed-off-by: Carlo Caione <ccaione@baylibre.com>	4 years ago
Carlo Caione	57f7e31017	drivers: PSCI: Add driver and subsystem Firmware implementing the PSCI functions described in ARM document number ARM DEN 0022A ("Power State Coordination Interface System Software on ARM processors") can be used by Zephyr to initiate various CPU-centric power operations. It is needed for virtualization, it is used to coordinate OSes and hypervisors and it provides the functions used for SMP bring-up such as CPU_ON and CPU_OFF. A new PSCI driver is introduced to setup a proper subsystem used to communicate with the PSCI firmware, implementing the basic operations: get_version, cpu_on, cpu_off and affinity_info. The current implementation only supports PSCI 0.2 and PSCI 1.0 The PSCI conduit (SMC or HVC) is setup reading the corresponding property in the DTS node.
