Alan Cox a6c6193a36 pcmcia: correct types
We should be using resource_size_t and unsigned types correctly, otherwise
we sign extend the flags on a 64bit box, which is not what we want.

Dominik Brodowski 1ac71e5a35 pcmcia: convert pcmcia_request_configuration to pcmcia_enable_device
pcmcia_enable_device() now replaces pcmcia_request_configuration().
Instead of config_req_t, all necessary flags are either passed as
a parameter to pcmcia_enable_device(), or (in rare circumstances)
set in struct pcmcia_device -> flags.

With the last remaining user of include/pcmcia/cs.h gone, remove
all references.

Dominik Brodowski 7feabb6412 pcmcia: move config_{base,index,regs} to struct pcmcia_device
Several drivers prefer to explicitly set config_{base,index,regs},
formerly known as ConfigBase, ConfigIndex and Present. Instead of
passing these values inside config_req_t, store it in struct
pcmcia_device.

Dominik Brodowski 37979e1546 pcmcia: simplify IntType
IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO
(all other drivers). As this flags seems to relate to ioport access, make
it conditional to the driver having requested IO port access. There are two
drivers which do not request IO ports, but did set INT_MEMORY_AND_IO:
ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

Dominik Brodowski fc30110103 pcmcia: simplify Status, ExtStatus register access
The Status (CISREG_CCSR) and ExtStatus (CISREG_ESR) registers were
only accessed to enable audio output for some drivers and IRQ for
serial_cs.c. The former also required setting config_req_t.Attributes
to CONF_ENABLE_SPKR; the latter can be simplified to setting this
field to CONF_ENABLE_ESR.

Future cleanups will follow, and will make up for the code
duplication currently present between rsrc_iodyn and rsrc_nonstatic

Magnus Damm 0bdf9b3dd3 pcmcia: Change window_handle_t logic to unsigned long
Logic changes based on top of the other patches:

This set of patches changed window_handle_t from being a pointer to an
unsigned long. The unsigned long is now a simple index into socket->win[].
Going from a pointer to unsigned long should leave the user space interface
unchanged unless I'm mistaken.

This change results in code that is less error prone and a user space
interface which is much cleaner and safer. A nice side effect is that we
are also are able to remove all members except one from window_t.

[ linux@dominikbrodowski.net:
	Update to 2.6.31. Also, a plain "index" to socket->win[] does not
	work, as several codepaths rely on "window_handle_t" being
	non-zero if used. Therefore, set the window_handle_t to the
	socket->win[] index + 1. ]

Dominik Brodowski 91284224da pcmcia: add new CIS access helpers
As a replacement to pcmcia_get_{first,next}_tuple() and
pcmcia_get_tuple_data(), three new -- and easier to use --
functions are added:

- pcmcia_get_tuple() to get the very first CIS entry of one
  type.

- pcmcia_loop_tuple() to loop over all CIS entries of one type.

- pcmcia_get_mac_from_cis() to read out the hardware MAC address
  from CISTPL_FUNCE.

Only a handful of drivers need these functions anyway, as most
CIS access is already handled by pcmcia_loop_config(), which
now shares the same backed (pccard_loop_tuple()) with
pcmcia_loop_tuple().

A pcmcia_get_mac_from_cis() bug noted by Komuro
<komurojun-mbn@nifty.com> has been fixed in this revision.

Dominik Brodowski 84897fc052 pcmcia: pccard_read_tuple and TUPLE_RETURN_COMMON cleanup
pccard_read_tuple(), which is only used by the PCMCIA core, should
handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which
may be 0) is requested, set tuple.Attributes = 0 as was done in all
PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the
"common" tuple. As to the callers of pccard_read_tuple():

- All calls to pcmcia_validate_cis() had set the "function" parameter to
  BIND_FN_ALL. Therefore, remove the "function" parameter and make the
  parameter to pccard_read_tuple explicit.

- Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL. This was
  already the case for calls to CISTPL_LONGLINK_MFC.
