Convert the pcmcia docs to ReST format. Most of the changes here are trivial. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

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.
