| |
The first 10 patches add a new function, of_get_cpu_hwid(), which parses CPU DT node 'reg' property, and then use it to replace all the open coded versions of parsing CPU node 'reg' properties.
The last 2 patches add support for populating the cacheinfo 'id' on DT platforms. The minimum associated CPU hwid is used for the id. The id is optional, but necessary for resctrl which is being adapted for Arm MPAM.
Tested on arm64. Compile tested on arm, x86 and powerpc.

Rob Herring (12): of: Add of_get_cpu_hwid() to read hardware ID from CPU nodes ARM: Use of_get_cpu_hwid() ARM: broadcom: Use of_get_cpu_hwid() arm64: Use of_get_cpu_hwid() csky: Use of_get_cpu_hwid() openrisc: Use of_get_cpu_hwid() powerpc: Use of_get_cpu_hwid() riscv: Use of_get_cpu_hwid() sh: Use of_get_cpu_hwid() x86: dt: Use of_get_cpu_hwid() cacheinfo: Allow for >32-bit cache 'id' cacheinfo: Set cache 'id' based on DT data
