sh: push-switch fixups for work_struct API damage.

2006-12-11T23:42:07+00:00

INIT_WORK() dropped the data arg, so now we have to stash an extra
pointer and backpedal instead.

sh: sh775x/titan fixes for irq header changes.

2006-12-06T03:05:02+00:00

The following moves the creation of IPR interupts into setup-7750.c
and updates a few other things to make it all work after the "Drop
CPU subtype IRQ headers" commit. It boots and runs fine on my titan
board.

 - adds an ipr_idx to the ipr_data and uses a function in the subtype
   code to calculate the address of the IPR registers

 - adds a function to enable individual interrupt mode for externals
   in the subtype code and calls that from the titan board code
   instead of doing it directly.

 - I changed the shift in the ipr_data to be the actual # of bits to
   shift, instead of the numnber / 4 - made it easier to match with
   the manual.

sh: dma-api channel capability extensions.

2006-12-06T01:45:39+00:00

This extends the SH DMA API for allowing handling of DMA
channels based off of their respective capabilities.

A couple of functions are added to the existing API,
the core bits are register_chan_caps() for registering
channel capabilities, and request_dma_bycap() for fetching
a channel dynamically based off of a capability set.

sh: Drop name overload in dma-sh.

2006-12-06T01:45:39+00:00

Pass along the dev_id from request_dma() all the way down,
rather than inserting an artificial name relating to the TEI
line that we were doing before.

This makes the line a bit less obvious, but dev_id is the proper
behaviour for this regardless.

sh: Make dma-isa depend on ISA_DMA_API.

2006-12-06T01:45:39+00:00

Previously we linked in the ISA DMA wrapper unconditionally.
As there are very few users of this, it's better to make it
conditional.

sh: dma-sysfs fixes.

2006-12-06T01:45:39+00:00

Handle the case where no registered DMACs exist somewhat more
gracefully. While we're at it, check for sysdev_create_file()
failing.

sh: generic push-switch framework.

2006-12-06T01:45:38+00:00

This adds support for a generic push switch framework. Adaptable for
various switches, including GPIO switches and the push switches commonly
found on Renesas debug boards.

This allows switch states to be trivially reported through sysfs.

sh: Drop CPU subtype IRQ headers.

2006-12-06T01:45:37+00:00

This drops the various IRQ headers that were floating around
and primarily providing hardcoded IRQ definitions for the
various CPU subtypes. This quickly got to be an unmaintainable
mess, made even more evident by the subtle breakage introduced
by the SH-2 and SH-2A changes.

Now that subtypes are able to register IRQ maps directly, just
rip all of the headers out.

sh: Fix IPR-IRQ's for IRQ-chip change breakage.

2006-10-31T03:53:28+00:00

The conversion from IPR-IRQ to IRQ-chip resulted in the
ipr data being allocated in a local variable in
make_ipr_irq - breaking anything using IPR interrupts.

This changes all of the callers of make_ipr_irq to
allocate a static structure containing the IPR data which
is then passed to make_ipr_irq. This removes the need for
make_ipr_irq to allocate any additional space for the IPR
information.

sh: Cleanup board header directories.

2006-10-19T07:30:32+00:00

Now with the ide.h mess sorted out, most of these boards
don't need their own directory. Move the headers out, and
update the driver paths.
