sh: maple: Support block reads and writes.

2009-02-27T07:07:32+00:00

This patch updates the maple bus to support asynchronous block reads
and writes as well as generally improving the quality of the code and
supporting concurrency (all needed to support the Dreamcast visual
memory unit - a driver will also be posted for that).

Changes in the bus driver necessitate some changes in the two maple bus
input drivers that are currently in mainline.

As well as supporting block reads and writes this code clean up removes
some poor handling of locks, uses an atomic status variable to serialise
access to devices and more robusly handles the general performance
problems of the bus.

maple: Kill useless private_data pointer.

2008-08-04T01:58:24+00:00

We can simply wrap in to the dev_set/get_drvdata(), there's no reason
to track an extra level of private data on top of the struct device.

maple: Clean up maple_driver_register/unregister routines.

2008-08-04T01:39:46+00:00

These were completely inconsistent. Clean these up to take a maple_driver
pointer directly for consistency.

sh/maple: clean maple bus code

2008-07-29T13:10:56+00:00

This patch cleans up the handling of the maple bus queue to remove
the risk of races when adding packets. It also removes references to the
redundant connect and disconnect functions.

maple: tidy maple_driver code by removing redundant connect/disconnect

2008-07-28T09:10:30+00:00

The connect and disconnect functions are unnecessary - everything they do can be
accomplished in the initial probe - so remove them.

maple: Drop unused prototypes from linux/maple.h.

2008-02-14T05:22:08+00:00

This patch removes the now unneeded registration check variable from
struct maple_device. (This patch assumes the include/linux/maple.h file
has already been patched for whitespace errors by
http://lkml.org/lkml/2008/2/6/327)

maple: fix up whitespace damage.

2008-02-14T05:22:07+00:00

This patch is fundamentally about fixing up the whitespace problems
introduced by my previous patch (that brought the code into mainline). A
second patch will follow that will fix memory leaks. The two need to be
applied sequentially.

sh: Add maple bus support for the SEGA Dreamcast.

2007-09-21T06:55:55+00:00

The Maple bus is SEGA's proprietary serial bus for peripherals
(keyboard, mouse, controller etc). The bus is capable of some
(limited) hotplugging and operates at up to 2 M/bits.

Drivers of one sort or another existed/exist for 2.4 and a rudimentary
port, which didn't support the 2.6 device driver model was also in
existence.

This driver - for the bus logic itself and for the keyboard (other
drivers will follow) are based on the code and concepts of those old
drivers but have lots of completely rewritten parts.

I have the maple bus code as a built in now as that seems the sane and
rational way to handle something like that - you either want the bus
or you don't.
