5 Matching of PCMCIA devices to drivers is done
6 following criteria:
7
8 - manufactor ID
9 - card ID
10 - product ID strings _and_ hashes of these str
11 - function ID
12 - device function (actual and pseudo)
13
14 You should use the helpers in include/pcmcia/d
15 struct pcmcia_device_id[] entries which match
16
17 If you want to match product ID strings, you a
18 hashes of the string to the macro, e.g. if you
19 string 1, you need to use
20
21 PCMCIA_DEVICE_PROD_ID1("some_string", 0x(hash_
22
23 If the hash is incorrect, the kernel will info
24 upon module initialization, and tell you of th
25
26 You can determine the hash of the product ID s
27 "modalias" in the sysfs directory of the PCMCI
28 in the following form:
29 pcmcia:m0149cC1ABf06pfn00fn00pa725B842DpbF1EFE
30
31 The hex value after "pa" is the hash of produc
32 string 2 and so on.
33
34 Alternatively, you can use crc32hash (see tool
35 to determine the crc32 hash. Simply pass the
36 as argument to this program, e.g.:
37 $ tools/pcmcia/crc32hash "Dual Speed"
