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