[RFC PATCH 12/38] arm64/sysreg: Standardise naming for ID_DFR1_EL1

James Morse james.morse at arm.com
Fri Sep 30 07:01:45 PDT 2022


To convert the 32bit id registers to use the sysreg generation, they
must first have a regular pattern, to match the symbols the script
generates.

Ensure symbols for the ID_DFR1_EL1 register have an _EL1 suffix.

No functional change.
