From 1aa3d0274a4aac338ee45a3dfc3b17c944bcc2bc Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Thu, 17 Aug 2023 11:24:03 +0530 Subject: arm_pmu: acpi: Add a representative platform device for TRBE ACPI TRBE does not have a HID for identification which could create and add a platform device into the platform bus. Also without a platform device, it cannot be probed and bound to a platform driver. This creates a dummy platform device for TRBE after ascertaining that ACPI provides required interrupts uniformly across all cpus on the system. This device gets created inside drivers/perf/arm_pmu_acpi.c to accommodate TRBE being built as a module.
