8 New PCMCIA IDs may be added to a device driver pcmcia_device_id table at
9 runtime as shown below::
10
11 echo "match_flags manf_id card_id func_id function device_no \
12 prod_id_hash[0] prod_id_hash[1] prod_id_hash[2] prod_id_hash[3]" > \
13 /sys/bus/pcmcia/drivers/{driver}/new_id
14
15 All fields are passed in as hexadecimal values (no leading 0x).
16 The meaning is described in the PCMCIA specification, the match_flags is
17 a bitwise or-ed combination from PCMCIA_DEV_ID_MATCH_* constants
18 defined in include/linux/mod_devicetable.h.
19
20 Once added, the driver probe routine will be invoked for any unclaimed
21 PCMCIA device listed in its (newly updated) pcmcia_device_id list.
22
23 A common use-case is to add a new device according to the manufacturer ID
24 and the card ID (form the manf_id and card_id file in the device tree).
25 For this, just use::
26
27 echo "0x3 manf_id card_id 0 0 0 0 0 0 0" > \
28 /sys/bus/pcmcia/drivers/{driver}/new_id
