Subject: arm64/sysreg: Update SMIDR_EL1 to DDI0601 2025-06
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=85b6f920a8691d96441da9da7fc55ec93b906fe6;p=thirdparty%2Flinux.git

arm64/sysreg: Update SMIDR_EL1 to DDI0601 2025-06

Update the definition of SMIDR_EL1 in the sysreg definition to reflect the
information in DD0601 2025-06. This includes somewhat more generic ways of
describing the sharing of SMCUs, more information on supported priorities
and provides additional resolution for describing affinity groups.
