This series enables detection of ACPI based TRBE devices via a stand alone
purpose built representative platform device. But as a pre-requisite this
changes coresight_platform_data structure assignment for the TRBE device.
This series is based on v6.5-rc4 kernel, is also dependent on the following
EDK2 changes posted earlier by Sami.
https://edk2.groups.io/g/devel/message/107239https://edk2.groups.io/g/devel/message/107241
Changes in V2:
- Refactored arm_spe_acpi_register_device() in a separate patch
- Renamed trbe_acpi_resources as trbe_resources
- Renamed trbe_acpi_dev as trbe_dev
Changes in V1:
