 * Property suffixes
 * -----------------
 *
 * These are the optional parts that come after the _P_<property>
 * part in DT_N_<path-id>_P_<property-id> macros, or the "prop-suf"
 * nonterminal in the DT guide's macros.bnf file.
 *
 * Before adding new ones, check this list to avoid conflicts. If any
 * are missing from this list, please add them. It should be complete.
 *
 * _ENUM_IDX: property's value as an index into bindings enum
 * _ENUM_VAL_<val>_EXISTS property's value as a token exists
 * _ENUM_TOKEN: property's value as a token into bindings enum (string
 *              enum values are identifiers) [deprecated, use _STRING_TOKEN]
 * _ENUM_UPPER_TOKEN: like _ENUM_TOKEN, but uppercased [deprecated, use
 *                    _STRING_UPPER_TOKEN]
 * _EXISTS: property is defined
 * _FOREACH_PROP_ELEM: helper for "iterating" over values in the property
 * _FOREACH_PROP_ELEM_VARGS: foreach functions with variable number of arguments
 * _IDX_<i>: logical index into property
 * _IDX_<i>_EXISTS: logical index into property is defined
 * _IDX_<i>_PH: phandle array's phandle by index (or phandle, phandles)
 * _IDX_<i>_STRING_TOKEN: string array element value as a token
 * _IDX_<i>_STRING_UPPER_TOKEN: string array element value as a uppercased token
 * _IDX <i>_STRING_UNQUOTED: string array element value as a sequence of tokens, with no quotes
 * _IDX_<i>_VAL_<val>: phandle array's specifier value by index
 * _IDX_<i>_VAL_<val>_EXISTS: cell value exists, by index
 * _LEN: property logical length
 * _NAME_<name>_PH: phandle array's phandle by name
 * _NAME_<name>_VAL_<val>: phandle array's property specifier by name
 * _NAME_<name>_VAL_<val>_EXISTS: cell value exists, by name
 * _STRING_TOKEN: string property's value as a token
 * _STRING_UPPER_TOKEN: like _STRING_TOKEN, but uppercased
 * _STRING_UNQUOTED: string property's value as a sequence of tokens, with no quotes

/*
 * @brief Test if any enabled node with the given compatible is on
 *        the given bus type
 *
 * This is like DT_ANY_INST_ON_BUS_STATUS_OKAY(), except it can also
 * be useful for handling multiple compatibles in single source file.
 *
 * Example devicetree overlay:
 *
 * @code{.dts}
 *     &i2c0 {
 *            temp: temperature-sensor@76 {
 *                     compatible = "vnd,some-sensor";
 *                     reg = <0x76>;
 *            };
 *     };
 * @endcode
 *
 * Example usage, assuming `i2c0` is an I2C bus controller node, and
 * therefore `temp` is on an I2C bus:
 *
 * @code{.c}
 *     DT_HAS_COMPAT_ON_BUS_STATUS_OKAY(vnd_some_sensor, i2c) // 1
 * @endcode
 *
 * @param compat lowercase-and-underscores compatible, without quotes
 * @param bus a binding's bus type as a C token, lowercased and without quotes
 * @return 1 if any enabled node with that compatible is on that bus type,
 *         0 otherwise
