2011-03-23w1: Silence ds1wm warnings related to mfd_get_cell changesAndres Salomon1-7/+2
mfd_get_cell returns a const, so change the ds1wm client to store a const mfd cell. This silences type mismatch warnings. Since we're guaranteed to have the mfd_cell, we can also simplify the code a bit to get rid of a temporary variable and NULL check.

2011-03-23w1: Use mfd_data instead of driver_data for dsw1wm.cAndres Salomon1-2/+2
Use mfd_data for passing information from mfd drivers to mfd clients. The mfd_cell's driver_data field is being phased out. Clients that were using driver_data now access .mfd_data via mfd_get_data(). This changes ds1wm only; mfd drivers with other cells are not modified, with the exception of led_cell. The led_cell.driver_data line is dropped from htc-pasic3.c in this patch as well. It's not used in mainline (there's no leds-pasic3 platform driver), so it should be safe to take care of that here.

2011-02-11drivers/w1/masters/omap_hdq.c: add missing clk_putJulia Lawall1-14/+14
This code makes two calls to clk_get, then test both return values and fails if either failed. The problem is that in the first inner if, where the first call to clk_get has failed, it don't know if the second call has failed as well. So it don't know whether clk_get should be called on the result of the second call. Of course, it would be possible to test that value again. A simpler solution is just to test the result of calling clk_get directly after each call. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ position p1,p2; expression e; statement S; @@ e = clk_get@p1(...) ... if@p2 (IS_ERR(e)) S @@ expression e; statement S; identifier l; position r.p1, p2 != r.p2; @@ *e = clk_get@p1(...) ... when != clk_put(e) *if@p2 (...) { ... when != clk_put(e) * return ...; }// </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Acked-by: Tony Lindgren <tony@atomide.com> Acked-by: Amit Kucheria <amit.kucheria@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-01-13w1: DS2423 counter driver and documentationMika Laitio4-0/+179
This is a 1-wire/w1 DS2423 slave driver for reading the values from all 4 counters available DS2423 devices by using standard w1_slave file. In ds2423 the counters are tied to ram pages 12-15 in and each of those ram-pages. Each of these counter values (and asoociated ram page values) are represented as a own line in w1_slave file.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo9-0/+9
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2010-03-07w1: move omap_hdq's probe function to .devinit.textUwe Kleine-König1-2/+2
A pointer to omap_hdq_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

There is no point in implementing a detect callback for the DS2482, as this device can't be detected.

The connector documentation states that the argument to the callback function is always a pointer to a struct cn_msg, but rather than encode it in the API itself, it uses a void pointer everywhere. This doesn't make much sense to encode the pointer in documentation as it prevents proper C type checking from occurring and can easily allow people to use the wrong pointer type.

2009-06-18w1-gpio: add external pull-up enable callbackDaniel Mack1-0/+35
On embedded devices, sleep mode conditions can be tricky to handle, Especially when processors tend to pull-down the w1 bus during sleep. Bus slaves (such as the ds2760) may interpret this as a reason for power-down conditions and entirely switch off the device. This patch adds a callback function pointer to let users switch on and off the external pull-up resistor. This lets the outside world know whether the processor is currently actively driving the bus or not. When this callback is not provided, the code behaviour won't change.

2009-04-05mfd: remove DS1WM clock handlingPhilipp Zabel1-20/+7
This driver requests a clock that usually is supplied by the MFD in which the DS1WM is contained. Currently, it is impossible for a MFD to register their clocks with the generic clock API due to different implementations across architectures. For now, this patch removes the clock handling from DS1WM altogether, trusting that the MFD enable/disable functions will switch the clock if needed.

2009-01-08w1: allow master IO commandsEvgeniy Polyakov1-65/+77
This small patchset extendes existing commands with reset, master IO and status messages. Reset is used to reset the bus for given master device, master IO command allows to initiate IO against bus itself not selecting slave device first, which can be used to probe the device for example. And status messages carry command completion status back to the userspace (namely very useful to get -ENODEV from when requested device was not found). Great thanks to Paul Alfille of OWFS for testing and commands suggestions. This patch: Allow starting of IO not against already found slave devices, but against the bus itself, which can be used for example to probe devices.

2009-01-08w1: list slaves commandsEvgeniy Polyakov1-17/+85
Initiates search (or alarm search) and returns all found devices to userspace. Found devices are not added into the system (i.e. they are not attached to family devices or bus masters), it will be done via (if was not done yet) usual timed searching.

2009-01-08w1: add list masters w1 commandEvgeniy Polyakov2-0/+57
This patch series introduces and extends several userspace commands used with netlink protocol. Touch block command allows to write data and return sampled data to the userspace. Extended search and alarm seach commands to return list of slave devices found during given search. List masters command allows to send all registered master IDs to the userspace. Great thanks to Paul Alfille (owfs) who tested this implementation and wrote w1-to-network daemon http://sourceforge.net/projects/w1repeater/ and Frederik Deweerdt and Randy Dunlap for review. This patch: Returns list of registered bus master devices.
