2008-03-10tifm: fix the MemoryStick host fifo handling codeAlex Dubov
Additional input received from JMicron on MemoryStick host interfaces showed that some assumtions in fifo handling code were incorrect. This patch also fixes data corruption used to occure during PIO transfers.

2008-02-09memstick: initial commit for Sony MemoryStick supportAlex Dubov
Sony MemoryStick cards are used in many products manufactured by Sony. They are available both as storage and as IO expansion cards. Currently, only MemoryStick Pro storage cards are supported via TI FlashMedia MemoryStick interface.

2007-05-08disable socket power in adapter driver instead of media oneAlex Dubov
Socket power must be fully controlled by adapter driver. This also prevents unnecessary power-off of the socket when media driver is unloaded, yet media remains in the socket. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2007-05-01tifm_sd: implement software scatter-gatherAlex Dubov
It was found that delays associated with issue and completion of the commands severely limit performance of the new, fast SD cards. To alleviate this issue scatter-gather emulation in software is implemented for both dma and pio transfer modes. Non-block aligned and high memory sg entries are accounted for.

2007-05-01tifm_sd: replace command completion state machine with full checkingAlex Dubov
State machine used to to track mmc command state was found to be fragile and unreliable, making many cards unusable. The safer solution is to perform all needed checks at every card event. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2007-05-01tifm: replace per-adapter kthread with freezeable workqueueAlex Dubov
Freezeable workqueue makes sure that adapter work items (device insertions and removals) would be handled after the system is fully resumed. Previously this was achieved by explicit freezing of the kthread. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2007-02-04tifm_7xx1: switch from workqueue to kthreadAlex Dubov
As there's only one work item (media_switcher) to handle and it's effectively serialized with itself, I found it more convenient to use kthread instead of workqueue. This also allows for a working implementation of suspend/resume, which were totally broken in the past version.

2007-02-04tifm_7xx1: Merge media insert and media remove functionsAlex Dubov
Hardware does not say whether card was inserted or removed when reporting socket events. Moreover, during suspend, media can be removed or switched to some other card type without notification. Therefore, for each socket in the change set the following is performed: 1. If there's active device in the socket it's unregistered 2. Media detection is performed 3. If detection recognizes supportable media, new device is registered This patch also alters some macros and variable names to enhance clarity.

2007-02-04tifm_sd: restructure initialization, removal and command handlingAlex Dubov
In order to support correct suspend and resume several changes were needed: 1. Switch from work_struct to tasklet for command handling. When device suspend is called workqueues are already frozen and can not be used. 2. Separate host initialization code from driver's probe and don't rely on interrupts for host initialization. This, in turn, addresses two problems: a) Resume needs to re-initialize the host, but can not assume that device interrupts were already re-armed. b) Previously, probe will return successfully before really knowing the state of the host, as host interrupts were not armed in time. Now it uses polling to determine the real host state before returning. 3. Separate termination code from driver's remove. Termination may be caused by resume, if media changed type or became unavailable during suspend. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
