linux.git/drivers/base/regmap, branch v3.3-rc1

Merge branch 'regmap/irq' into regmap-next

2011-12-05T16:21:05+00:00

regmap: Add irq_base accessor to regmap_irq

2011-12-05T16:13:31+00:00

Allows devices to discover their own interrupt without having to remember
it themselves.

regmap: Allow drivers to reinitialise the register cache at runtime

2011-12-05T13:17:36+00:00

Sometimes the register map information may change in ways that drivers can
discover at runtime. For example, new revisions of a device may add new
registers. Support runtime discovery by drivers by allowing the register
cache to be reinitialised with a new function regmap_reinit_cache() which
discards the existing cache and creates a new one.

regmap: Add trace event for successful cache reads

2011-11-30T20:51:09+00:00

Currently we only trace physical reads, there's no instrumentation if
the read is satisfied from cache.

regmap: Allow regmap_update_bits() users to detect changes

2011-11-29T20:15:50+00:00

Some users of regmap_update_bits() would like to be able to tell their
users if they actually did an update so provide a variant which also
returns a flag indicating if an update took place. We could return a
tristate in the return value of regmap_update_bits() but this makes the
API more cumbersome to use and doesn't fit with the general zero for
success idiom we have.

regmap: Report if we actually handled an interrupt in regmap-irq

2011-11-28T18:51:57+00:00

While the IRQ core doesn't currently support shared threaded interrupts
that's no reason for drivers not to do their bit and report IRQ_NONE when
they don't get an interrupt. This allows the core spurious/wedget interrupt
detection support to do its thing.

regmap: Fix rbtreee build when not using debugfs

2011-11-22T11:43:01+00:00

The debugfs functions don't stub themselves out quite so well as might
be desirable so provide functions which do do this stubbing.

regmap: Provide debugfs dump of the rbtree cache data

2011-11-21T19:50:10+00:00

Show the register ranges we have in each rbtree node in debugfs, plus
some statistics on how big each node is and the total number of nodes.
It may also be worth collecting data on the ranges of dirty registers
to see if there's much mileage in trying to coalesce writes on sync.
