Merge tag 'acpi-pcc-updates-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux
Merge ACPI PCC changes for v6.7 from Sudeep Holla: "ACPI: PCC: Mailbox and generic updates for v6.7 Main updates include: 1. Addition of support for Type 4 PCC subspace that enables platform notification handling (Huisong Li). 2. Support for the shared interrupt amongst multiple PCC subspaces/ channels (Huisong Li). 3. Consolidation of PCC shared memory region command and status bitfields definitions that were duplicated and scattered across multiple PCC client drivers (Sudeep Holla)." * tag 'acpi-pcc-updates-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: soc: kunpeng_hccs: Migrate to use generic PCC shmem related macros hwmon: (xgene) Migrate to use generic PCC shmem related macros i2c: xgene-slimpro: Migrate to use generic PCC shmem related macros ACPI: PCC: Add PCC shared memory region command and status bitfields mailbox: pcc: Support shared interrupt for multiple subspaces mailbox: pcc: Add support for platform notification handling
