memstick: fix MSProHG 8-bit interface mode support

2008-09-13T21:41:52Z

- 8-bit interface mode never worked properly. The only adapter I have which supports the 8b mode (the Jmicron) had some problems with its clock wiring and they discovered it only now. We also discovered that ProHG media is more sensitive to the ordering of initialization commands. - Make the driver fall back to highest supported mode instead of always falling back to serial. The driver will attempt the switch to 8b mode for any new MSPro card, but not all of them support it. Previously, these new cards ended up in serial mode, which is not the best idea (they work fine with 4b, after all). - Edit some macros for better conformance to Sony documentation Signed-off-by: Alex Dubov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

memstick: use fully asynchronous request processing

2008-07-26T19:00:04Z

Instead of using a separate thread to pump requests from block layer queue to memstick, do so inline, utilizing the callback design of the memstick. [akpm@linux-foundation.org: fix warnings] Signed-off-by: Alex Dubov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

memstick: add "start" and "stop" methods to memstick device

2008-07-26T19:00:04Z

In some cases it may be desirable to ensure that associated driver is not going to access the media in some period of time. "start" and "stop" methods are provided therefore to allow it. Signed-off-by: Alex Dubov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

memstick: allow "set_param" method to return an error code

2008-07-26T19:00:04Z

Some controllers (Jmicron, for instance) can report temporal failure condition during power-on. It is desirable to account for this using a return value of "set_param" device method. The return value can also be handy to distinguish between supported and unsupported device parameters in run time.

driver core: remove DEVICE_ID_SIZE define

2008-07-22T04:54:53Z

There is no such thing as a "device id size" in the driver core, so remove the define and fix up any users of this odd define in the rest of the kernel. Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman

memstick: convert struct class_device to struct device

2008-04-20T02:10:29Z

struct class_device is going away, struct device should be used instead. Signed-off-by: Tony Jones Signed-off-by: Kay Sievers Cc: Alex Dubov Signed-off-by: Greg Kroah-Hartman

memstick: suppress uninitialized-var warning

memstick: optimize setup of JMicron host parameters

Set correct clock management values to improve over-all performance. Signed-off-by: Alex Dubov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

memstick: add support for 8-bit parallel mode

2008-03-20T01:53:37Z

Newer MemoryStick (HG) cards and hosts support 8-bit parallel mode of operation in addition to original 4-bit and 1-bit modes. Signed-off-by: Alex Dubov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

memstick: automatically retrieve "INT" value from command response

2008-03-20T01:53:37Z

MemoryStick storage cards, when in parallel mode, send several meaningful bits of their "INT" register as part of command response. This data is stored by host and can be used to spare invocation of "GET_INT" TPC on each data page transferred between host and card.
