imx: mx7: psci: provide complete PSCI 1.0 implementation
PSCI 1.0 require PSCI_VERSION, PSCI_FEATURES, AFFINITY_INFO and CPU_SUSPEND to be implemented. Commit 0ec3d98f ("mx7_common: use psci 1.0 instead of 0.1") marked the i.MX 7 implementation to be PSCI 1.0 compliant but failed to implement those functions. Especially the missing PSCI version callback was noticeable when booting Linux: [ 0.000000] psci: probing for conduit method from DT. [ 0.000000] psci: PSCIv65535.65535 detected in firmware. [ 0.000000] psci: Using standard PSCI v0.2 function IDs [ 0.000000] psci: MIGRATE_INFO_TYPE not supported. [ 0.000000] psci: SMC Calling Convention v1.0 This patch provides a minimal implementation thereof. With this patch applied Linux detects PSCI 1.0: [ 0.000000] psci: probing for conduit method from DT. [ 0.000000] psci: PSCIv1.0 detected in firmware. [ 0.000000] psci: Using standard PSCI v0.2 function IDs [ 0.000000] psci: MIGRATE_INFO_TYPE not supported.
