2010-08-09tx493xide: use min_t() macro instead of min()Atsushi Nemoto
This fixes a warning ("comparison of distinct pointer types lacks a cast") introduced by the commit 040f6b4f14adb2ca5babb84e9fb2ebc6661e0be2 ("tx493xide: use ->pio_mode value to determine pair device speed").

2010-01-19tx493xide: use ->pio_mode value to determine pair device speedBartlomiej Zolnierkiewicz
Use the current PIO mode value instead of the physical maximum one of the pair device on the port to determine PIO commmand timings used for both devices on the port. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-05-17ide: remove hw_regs_t typedefBartlomiej Zolnierkiewicz
Remove hw_regs_t typedef and rename struct hw_regs_s to struct ide_hw. There should be no functional changes caused by this patch. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-05-17ide: pass number of ports to ide_host_{alloc,add}() (v2)Bartlomiej Zolnierkiewicz
Pass number of ports to ide_host_{alloc,add}() and then update all users accordingly. v2: - drop no longer needed NULL initializers in buddha.c, cmd640.c and gayle.c (noticed by Sergei) There should be no functional changes caused by this patch.

2009-04-08tx493[89]ide: Remove big endian version of tx493[89]ide_tf_{load,read}Atsushi Nemoto
Now tx493[89]ide_tf_{load,read} do not contain word I/O operations. They are endian-free now. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Sergei Shtylyov <sshtylyov@ru.mvista.com>, Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-03-31ide: turn selectproc() method into dev_select() method (take 5)Sergei Shtylyov
Turn selectproc() method into dev_select() method by teaching it to write to the device register and moving it from 'struct ide_port_ops' to 'struct ide_tp_ops'. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: benh@kernel.crashing.org Cc: petkovbb@gmail.com [bart: add ->dev_select to at91_ide.c and tx4939.c (__BIG_ENDIAN case)] Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-03-31ide: move data register access out of tf_{read|load}() methods (take 2)Sergei Shtylyov
Move IDE_FTFLAG_{IN|OUT}_DATA flag handling out of tf_{read|load}() methods into the only two functions where these flags actually need to be handled: do_rw_taskfile() and ide_complete_cmd()...

2009-03-31ide: call {in|out}put_data() methods from tf_{read|load}() methods (take 2)Sergei Shtylyov
Handle IDE_FTFLAG_{IN|OUT}_DATA flags in tf_{read|load}() methods by calling {in|out}put_data() methods to transfer 2 bytes -- this will allow us to move that handling out of those methods altogether...

2009-03-31ide: rename IDE_TFLAG_IN_[HOB_]FEATURESergei Shtylyov
The feature register has never been readable -- when its location is read, one gets the error register value; hence rename IDE_TFLAG_IN_[HOB_]FEATURE into IDE_TFLAG_IN_[HOB_]ERROR and introduce the 'hob_error' field into the 'struct ide_taskfile' (despite the error register not really depending on the HOB bit).

2009-03-31ide: turn set_irq() method into write_devctl() methodSergei Shtylyov

2009-03-27ide: pass command instead of request to ide_pio_datablock()Bartlomiej Zolnierkiewicz
* Add IDE_TFLAG_FS taskfile flag and set it for REQ_TYPE_FS requests. * Convert ->{in,out}put_data methods to take command instead of request as an argument. Then convert pre_task_out_intr(), task_end_request(), task_error(), task_in_unexpected(), ide_pio_sector(), ide_pio_multi() and ide_pio_datablock() in similar way. * Rename task_end_request() to ide_finish_cmd(). There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-03-27ide: remove ide_task_t typedefBartlomiej Zolnierkiewicz
While at it: - rename struct ide_task_s to struct ide_cmd - remove stale comments from idedisk_{read_native,set}_max_address() - drop unused 'cmd' argument from ide_{cmd,task}_ioctl() - drop unused 'task' argument from tx4939ide_tf_load_fixup() - rename ide_complete_task() to ide_complete_cmd() - use consistent naming for struct ide_cmd variables There should be no functional changes caused by this patch.

2009-03-27ide: add "flagged" taskfile flags to struct ide_taskfile (v2)Bartlomiej Zolnierkiewicz
* Add ->ftf_flags field to struct ide_taskfile and convert flags for TASKFILE ioctl to use it. * Rename "flagged" taskfile flags: - IDE_TFLAG_FLAGGED -> IDE_FTFLAG_FLAGGED - IDE_TFLAG_FLAGGED_SET_IN_FLAGS -> IDE_FTFLAG_SET_IN_FLAGS - IDE_TFLAG_{OUT,IN}_DATA -> IDE_FTFLAG_{OUT,IN}_DATA v2: * Remember to fully update ide-h8300.c, scc_pata.c and tx493{8,9}ide.c (thanks to Stephen Rothwell for noticing).

2008-11-02tx4938ide: Check minimum cycle time and SHWT range (v2)Atsushi Nemoto
SHWT value is used as address valid to -CSx assertion and -CSx to -DIOx assertion setup time, and contrarywise, -DIOx to -CSx release and -CSx release to address invalid hold time, so it actualy applies 4 times and so constitutes -DIOx recovery time. Check requirement of the recovery time and cycle time. Also check SHWT maximum value.
