Some attributes have valid values that need to be converted
to integer tuple values before it is appended to the
object's private data:
For ex, the buffer widget object's "caps" attribute has the
following definition:
DefineAttribute."caps" {
type "string"
# Token reference and type
token_ref "sof_tkn_buffer.word"
constraints {
value_ref "sof_tkn_mem"
valid_values [
"dai"
"host"
"pass"
"comp"
]
tuple_values [
113
113
113
65
]
}
}
Depending on the user input, the value string values for "caps"
will be converted to the appropriate tuple values.
