Big w1 update.
Main featureas are:
- ds9490 transport driver
- simple 64bit rom driver
- w1_ops extension
- dynamic slave removal
Please apply attached big patches(diff.1 then diff.2), splitted little
patches will be sent in next e-mails for reviewing, but they can not be
applied to the linux kernel tree since sync with in-tree driver was made
in the last patch.
Thank you.

2004-07-25 19:52:42 GMT Evgeniy Poluakov <johnpol at 2ka.mipt.ru> patch-11
Summary:
Added dynamic slave removal mechanism. Fixed bug when we have
multiple slave with different families.
Revision:
w1--main--0--patch-11
Added dynamic slave removal mechanism by introducing u32 flags; in
each slave.
If slave was found during search process then set flag.
If after search complete we have slave entryes without magic
flag then remove them.
Fixed bug when we have multiple slave with different families.
Since attributes were static then each new family will rewrite
static values with new
function pointers... badly broken.
Master processing now still has static attributes. Needs to
check.

Summary:
Added w1_check_family().
Revision:

2004-07-25 16:36:48 GMT Evgeniy Poluakov <johnpol at 2ka.mipt.ru> patch-6
Summary:
Added "i" and "r" scripts. Added w1_read_block() and
w1_write_block() callbacks.
Revision:
w1--main--0--patch-6
Added "i" and "r" scripts.
Added w1_read_block() and w1_write_block().
w1_therm.c now uses them.
w1_therm: Chnaged snprintf to sprintf in w1_therm_read_bin() and
added max_trying -
number of tryings to read temperature before failng. By default
it is 10.
Added w1_therm_check_rom() - checks if read rom is in black
list.
If rom is in black list it is probably due to unsufficient of
"power" in the sensor -
either add strong pullup or connect it to Vcc.

Summary:
Added callbacks for read_block() and write_block(). Changed
ds_start_pulse(), now byte/block writings use it. Other additions.
Revision:
ds9490r--main--0.1--patch-5
Added callbacks for read_block() and write_block().
Changed ds_start_pulse(), now byte/block writings use it.
Disable for now mode command in it. They are broken.
ds_start_pulse() now has second argument - number of
milliseconds pulse duration will take.
Added ds_set_path(), ds_match_access(), ds_search(),
ds_write_block(), ds_read_block().
ds_recv_data() returnes number of cytes read or negativ error code.
The same ds_read_block() does.
Reverted changes in ds_read_bit() - if you need to _read_ bit from
w1 - read it, if you need only to
read data from EP3 use touch bit or ds_recv_data()...
Added COMM_SPU bit into the writing routings, but it looks like it
is not working.
Removed some commented code.
ds_w1_bridge.c now uses touch_bit() instead of read/write_bit().

2004-07-21 06:50:42 GMT Evgeniy Polyakov <johnpol at 2ka.mipt.ru> patch-3
Summary:
Debug removal, status copying, debug output changes,
ds_wait_status(), ds_touch_bit(), ds_recv_data() changes, struct
ds_status changes.
Revision:
ds9490r--main--0.1--patch-3
Removed some debug printks.
Typo in status copying code - s/sizeof(st)/sizeof(*st).
Changed debug output: exchanged input and output buffer status,
since they need(and already are) to be exchanged in struct ds_status.
ds_wait_status() - waits until max attempts or error occures.
ds_touch_bit() - typo in "value" parameter[I wonder if Dallas even
tries to compile their cruft with non MS compiler],
waits untill max attempts or last command in status is equal to
"value".
ds_recv_data() returns negative error code or number of bytes read.
Exchanged input and output buffer status instruct ds_status.

Makefile dscore.c dscore.h
2004-07-18 21:48:27 GMT Evgeniy Polyakov <johnpol at 2ka.mipt.ru> patch-2
Summary:
Added ds_touch_bit(), ds_wait_status(), various changes changed.
Revision:
ds9490r--main--0.1--patch-2
Added ds_touch_bit(), ds_wait_status().
Changes ds_read_bit() - only ds_recv_data() and send BIT_IO, do not
enable pulse..
ds_probe() resets configuration and sets interface 3.
ds_read_byte() waits for status and compares read value with 0xff -
if read value is equal to 0xff then nothing was read.
ds_write_byte() sends control byte_io command, then waiting for the
status and then
reads back just written value and compares it with written
value.
If they do not match then write failed.
ds_write_bit() sends control and waits for the status.
ds_reset() sends 0x43 control byte and waits for the status.
ds_recv_data() - must reveive data from ->ep[EP_DATA_IN] not from
EP_DATA_IN.
If error occured then usb_clear_halt() this endpoint and dump
status.
ds_touch_bit() - sends bit_io command and bit, then waits for the
status, then
receives data from ep3.
ds_wait_status() - read status without dumping it until 100 times
"good" status received.

Added ds_w1_bridge.c, code cleanup.
Revision:
ds9490r--main--0.1--patch-1
Added ds_w1_bridge.c - DS9490R<-->W1 master bridge driver.
Code cleanup: read/write functions, reset, hw reset and many other,
s/ds9490r/ds.
Added reference counter into main structure - FIXME, it takes too
lonmg to unload, race somewhere.
