50 of device-identifying data for use by
55 that describes the memory layout of table entries.
56 The string is a series of members separated by semi-colons.
57 Members are identified by a type and a name.
58 They are encoded in the descriptor string by concatenating the type with a
59 colon, followed by the name.
62 represents two members.
63 The first name is encoded like any other type.
64 The second name is encoded by appending a forward slash and the second
65 name after the first.)
67 Types are one of the following:
75 except that the sentinel value 0xFF matches any.
78 element; any value greater than or equal matches.
81 element; any value less than or equal matches.
84 element; mask of which of the following fields to use.
91 except that the sentinel value 0xFFFF matches any.
98 except that the sentinel value 0xFFFFFFFF matches any.
102 values; the first named member is in the least significant word and the second
103 named member is in the most significant word.
105 A pointer to a string to match exactly.
107 A pointer to a human readable description for the device.
109 A pointer that should be ignored.
113 PNP info that's true for the for the whole table.
114 The driver code checks for these condition pragmatically before using
115 this table to match devices.
116 This item must come last in the list.
121 is reserved for fields that should be ignored.
122 Any member that does not match the parent device's pnpinfo output must be
127 parameter is an unquoted word naming the parent bus of the driver.
133 parameter is also an unquoted word.
134 It must be unique to the driver.
135 Usually the driver's name is used.
139 parameter points to the device matching data with entries matching the
140 .Fa descriptor_string .
144 parameter is the size of each table entry, i.e.,
145 .Ql sizeof(table[0]) .
149 parameter is the number of entries in the table, i.e.,
151 Note that only valid entries should be included.
152 If the table contains trailing zero or bogus values, they should not be
