[PATCH v5 06/28] arm64/sysreg: Add _EL1 into ID_AA64PFR0_EL1 definition names
Mark Brown
broonie at kernel.org
Tue Aug 30 03:21:21 PDT 2022
Normally we include the full register name in the defines for fields within
registers but this has not been followed for ID registers. In preparation
for automatic generation of defines add the _EL1s into the defines for
ID_AA64PFR0_EL1 to follow the convention. No functional changes.
