0008 New PCMCIA IDs may be added to a device driver pcmcia_device_id table at
0009 runtime as shown below::
0010
0011 echo "match_flags manf_id card_id func_id function device_no \
0012 prod_id_hash[0] prod_id_hash[1] prod_id_hash[2] prod_id_hash[3]" > \
0013 /sys/bus/pcmcia/drivers/{driver}/new_id
0014
0015 All fields are passed in as hexadecimal values (no leading 0x).
0016 The meaning is described in the PCMCIA specification, the match_flags is
0017 a bitwise or-ed combination from PCMCIA_DEV_ID_MATCH_* constants
0018 defined in include/linux/mod_devicetable.h.
0019
0020 Once added, the driver probe routine will be invoked for any unclaimed
0021 PCMCIA device listed in its (newly updated) pcmcia_device_id list.
0022
0023 A common use-case is to add a new device according to the manufacturer ID
0024 and the card ID (form the manf_id and card_id file in the device tree).
0025 For this, just use::
0026
0027 echo "0x3 manf_id card_id 0 0 0 0 0 0 0" > \
0028 /sys/bus/pcmcia/drivers/{driver}/new_id
0029
0030 after loading the driver.
