[PATCH v2 2/9] arm64/sysreg: Standardise ID_AA64ISAR0_EL1 macro names
Mark Brown
broonie at kernel.org
Wed Mar 16 10:08:42 PDT 2022
The macros for accessing fields in ID_AA64ISAR0_EL1 omit the _EL1 from the
name of the register. In preparation for converting this register to be
automatically generated update the names to include an _EL1, there should
be no functional change.
