/*
 * This file contains definitions for various T4 register value hardware
 * constants.  The types of values encoded here are predominantly those for
 * register fields which control "modal" behavior.  For the most part, we do
 * not include definitions for register fields which are simple numeric
 * metrics, etc.
 *
 * These new "modal values" use a naming convention which matches the
 * currently existing macros in t4_reg.h.  For register field FOO which would
 * have S_FOO, M_FOO, V_FOO() and G_FOO() macros, we introduce X_FOO_{MODE}
 * definitions.  These can be used as V_FOO(X_FOO_MODE) or as (G_FOO(x) ==
 * X_FOO_MODE).
 *
 * Note that this should all be part of t4_regs.h but the toolset used to
 * generate that file doesn't [yet] have the capability of collecting these
 * constants.
