2009-01-07hwmon: (f71882fg) Cleanup fan and temp hyst functionsHans de Goede
Simplify fan and temp hyst. handling by treating the registers as an array of nibbles instead of using switch cases. Also unify the way hysts are handled between temp and fans, the temp code was storing the actual per temp hyst values in 4 u8's, where as the fan code was storing actual register values.

2009-01-07hwmon: (f71882fg) Fix various sysfs callback function issuesHans de Goede
While working on adding F8000 support I noticed that various of the store sysfs functions (and a few of the show also) had issues. This patch fixes the following issues in these functions: * store: storing the result of strto[u]l in an int, resulting in a possible overflow before boundary checking * store: use of f71882fg_update_device(), we don't want to read the whole device in store functions, just the registers we need * store: use of cached register values instead of reading the needed regs in the store function, including cases where f71882fg_update_device() was not used, this could cause real isues * show: shown value is a calculation of 2 or more cached register reads, without locking the data struct.

2009-01-07hwmon: (f71882fg) Prepare for adding F8000 supportHans de Goede
This patch is a preparation patch for adding F8000 support to the f71882fg driver. If you look at the register addresses and esp, the bits used for the temperature channels, then you will notice that it appears that they start at 1 in a system meant to start at 0. As the F8000 actually uses the 0 addresses and bits, this patch changes the f71882fg driver to take 4 temperatures numbered 0-3 in to account, using 1-3 in this new scheme for the temperatures actually present in the F718x2FG.

2009-01-07hwmon: (f71882fg) Move some io access from the detect to the probe functionHans de Goede
The f71882fg driver did some io to ioports it hadn't reserved yet in its find (detect) function, this patches moves this io to the probe function where these ports are reserved and this io belongs. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2009-01-07hwmon: (f71882fg) Add PWM supportMark van Doesburg
Add PWM (fan speed control) support to the f71882fg driver. Both manual control and automatic (temperature-based) modes are supported. Additionally, each mode has a PWM-based and an RPM-based variant. By default we use the mode set by the BIOS.

2009-01-07Blackfin arch: Faster C implementation of no-MPU CPLB handlerBernd Schmidt
This is a mixture ofcMichael McTernan's patch and the existing cplb-mpu code. We ditch the old cplb-nompu implementation, which is a good example of why a good algorithm in a HLL is preferrable to a bad algorithm written in assembly. Rather than try to construct a table of all posible CPLBs and search it, we just create a (smaller) table of memory regions and their attributes. Some of the data structures are now unified for both the mpu and nompu cases. A lot of needless complexity in cplbinit.c is removed. Further optimizations: * compile cplbmgr.c with a lot of -ffixed-reg options, and omit saving these registers on the stack when entering a CPLB exception. * lose cli/nop/nop/sti sequences for some workarounds - these don't * make sense in an exception context Additional code unification should be possible after this. [Mike Frysinger <vapier.adi@gmail.com>: - convert CPP if statements to C if statements - remove redundant statements - use a do...while loop rather than a for loop to get slightly better optimization and to avoid gcc "may be used uninitialized" warnings ... we know that the [id]cplb_nr_bounds variables will never be 0, so this is OK - the no-mpu code was the last user of MAX_MEM_SIZE and with that rewritten, we can punt it - add some BUG_ON() checks to make sure we dont overflow the small cplb_bounds array - add i/d cplb entries for the bootrom because there is functions/data in there we want to access - we do not need a NULL trailing entry as any time we access the bounds arrays, we use the nr_bounds variable ] Signed-off-by: Michael McTernan <mmcternan@airvana.com> Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bernd Schmidt <bernds_cb1@t-online.de> Signed-off-by: Bryan Wu <cooloney@kernel.org>
