2009-09-22regulator: Add regulator voltage range check APIMark Brown
Simplify checking of support for voltage ranges by providing an API which wraps the existing count and list operations. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
2009-09-22regulator: Add regulator_get_exclusive() APIMark Brown
Some consumers require complete control of the regulator and can't tolerate sharing it with other consumers, most commonly because they need to have the regulator actually disabled so can't have other consumers forcing it on. This new regulator_get_exclusive() API call allows these consumers to explicitly request this, documenting the assumptions that they are making. In order to simplify coding of such consumers the use count for regulators they request is forced to match the enabled state of the regulator when it is requested. This is not possible for consumers which can share regulators due to the need to keep track of the ownership of use counts. A new API call is used rather than an additional argument to the existing regulator_get() in order to avoid merge headaches with driver code in other trees.

2009-09-22regulator: replace ADTV1 register by ADTV2 in da903xHaojian Zhuang
In PXA3xx SoC family, V_CORE power doamin is supplied by BUCK1 that is controller by ADTV1 or ADTV2 register. By default, v1 and v2 has the same copy. If v1 or v2 is updated, the last value that is written to either register takes effect. It means that v1 and v2 has different copy. And the actual voltage output is determinated by last update on either register. DA9034/35 is binded with PXA3xx SoC family. While SoC is scaling OP or entering/exiting lower power mode, SoC needs to change voltage of V_CORE power doamin. In order to be efficient, POWER I2C (hardcode) mode could be enabled in SoC. In this mode, SoC will control v2 register directly. In original DA903x driver, software will only read regulator data from v1 register. But SoC controls v2 register directly. It results that v1 and v2 isn't synchronized. Wrong data will be read from v1 register. So access v2 register in da903x driver instead.

2009-09-22regulator: Allow consumer supplies to be set up with dev_name()Mark Brown
Follow the approach suggested by Russell King and implemented by him in the clkdev API and allow consumer device supply mapings to be set up using the dev_name() for the consumer instead of the struct device. In order to avoid making existing machines instabuggy and creating merge issues the use of struct device is still supported for the time being. This resolves problems working with buses such as I2C which make the struct device available late providing that the final device name is known, which is the case for most embedded systems with fixed setups. Consumers must still use the struct device when calling regulator_get(). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>

2009-09-21nfs: initialize the backing_dev_info when creating the serverJens Axboe
NFS may free the server structure without ever having used the bdi, so we either need to flag the bdi as being uninitialized or initialize it up front. This does the latter.

2009-09-21perf: Do the big rename: Performance Counters -> Performance EventsIngo Molnar
Bye-bye Performance Counters, welcome Performance Events! In the past few months the perfcounters subsystem has grown out its initial role of counting hardware events, and has become (and is becoming) a much broader generic event enumeration, reporting, logging, monitoring, analysis facility. Naming its core object 'perf_counter' and naming the subsystem 'perfcounters' has become more and more of a misnomer. With pending code like hw-breakpoints support the 'counter' name is less and less appropriate. All in one, we've decided to rename the subsystem to 'performance events' and to propagate this rename through all fields, variables and API names. (in an ABI compatible fashion) The word 'event' is also a bit shorter than 'counter' - which makes it slightly more convenient to write/handle as well. Thanks goes to Stephane Eranian who first observed this misnomer and suggested a rename. User-space tooling and ABI compatibility is not affected - this patch should be function-invariant. (Also, defconfigs were not touched to keep the size down.) This patch has been generated via the following script: FILES=$(find * -type f | grep -vE 'oprofile|[^K]config') sed -i \ -e 's/PERF_EVENT_/PERF_RECORD_/g' \ -e 's/PERF_COUNTER/PERF_EVENT/g' \ -e 's/perf_counter/perf_event/g' \ -e 's/nb_counters/nb_events/g' \ -e 's/swcounter/swevent/g' \ -e 's/tpcounter_event/tp_event/g' \ $FILES for N in $(find . -name perf_counter.[ch]); do M=$(echo $N | sed 's/perf_counter/perf_event/g') mv $N $M done FILES=$(find . -name perf_event.*) sed -i \ -e 's/COUNTER_MASK/REG_MASK/g' \ -e 's/COUNTER/EVENT/g' \ -e 's/\<event\>/event_id/g' \ -e 's/counter/event/g' \ -e 's/Counter/Event/g' \ $FILES ... to keep it as correct as possible. This script can also be used by anyone who has pending perfcounters patches - it converts a Linux kernel tree over to the new naming. We tried to time this change to the point in time where the amount of pending patches is the smallest: the end of the merge window. Namespace clashes were fixed up in a preparatory patch - and some stylistic fallout will be fixed up in a subsequent patch. ( NOTE: 'counters' are still the proper terminology when we deal with hardware registers - and these sed scripts are a bit over-eager in renaming them. I've undone some of that, but in case there's something left where 'counter' would be better than 'event' we can undo that on an individual basis instead of touching an otherwise nicely automated patch. ) Suggested-by: Stephane Eranian <eranian@google.com> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Paul Mackerras <paulus@samba.org> Reviewed-by: Arjan van de Ven <arjan@linux.intel.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: David Howells <dhowells@redhat.com> Cc: Kyle McMartin <kyle@mcmartin.ca> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "David S.

2009-09-20loongson: fix cut-and-paste mis-mergeLinus Torvalds
Ingo points out that I screwed up when merging the 'timers-for-linus' branch in commit a03fdb7612874834d6847107198712d18b5242c7. A bit too much copy-and-pasting caused the end result to have an extraneous 'return' in the middle of an expression. That was obviously bogus. Blush.

2009-09-20x86: Print the hypervisor returned tsc_khz during bootAlok Kataria
On an AMD-64 system the processor frequency that is printed during system boot, may be different than the tsc frequency that was returned by the hypervisor, due to the value returned from calibrate_cpu. For debugging timekeeping or other related issues it might be better to get the tsc_khz value returned by the hypervisor. The patch below now prints the tsc frequency that the VMware hypervisor returned.
