I2C_CLIENT_MODULE_PARM is overkill for force_subclients. We really only use 4 out of the 48 slots, so we're better defining a custom variable instead. This change saves 92 bytes of data for each of the five drivers affected. Signed-off-by:

The RPM after conversion from / before conversion to a register value can be much more than 65535 (up to 1500000), so putting this into an u16 can cause overflows. This changes the functions to use an int to store / get RPM instead. Signed-off-by:

Add some documentation about the f71882fg driver, and update the Kconfig documentation to report the new supported models. Signed-off-by:

For some reason the fan_attr array for the f71862fg was missing the attr for the 3th pwm output. This patch fixes this. Signed-off-by:

Remove the fan_mode module option it was a monstrosity to begin with, and when adding support for the F8000 it becomes a real pain! Signed-off-by:

While studying the datasheets for adding F8000 support, I noticed that the F718x2 has separate alarms (and beep control) for its max and crit limits. We keep the temp#_alarm attributes as they are, even though it would be more logical to rename them to temp#_max_alarm. Because lm_sensors v2 depends on them. Signed-off-by:

More F8000 prep work. Take over the checking if the hwmon part is not powered down from the standalone f8000 driver. This check is valid for all supported models. Signed-off-by:

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.

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.

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.

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:

This patch adds support for the Fintek f71862fg superio monitoring functions to the f71882fg driver. This support has been tested without problems on a Jetway J9F2 by Tony McConnell. Signed-off-by:

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. Signed-off-by:

The __SWAB_64_THRU_32__ case of a 64-bit byte swap was depending on the no-longer-existant ___swab32() method (three underscores). We got rid of some of the worst indirection and complexity, and now it should just use the 32-bit swab function that was defined right above it. Reported-and-tested-by:

The first step to make swab.h a regular header that will include an asm/swab.h with arch overrides. Avoid the gratuitous differences introduced in the new linux/swab.h by naming the ___constant_swabXX bits and __fswabXX bits exactly as found in the old implementation in byteorder/swab[b].h Use this new swab.h in byteorder/[big|little]_endian.h and remove the two old swab headers. Although the inclusion of asm/byteorder.h looks strange in linux/swab.h, this will allow each arch to move the actual arch overrides for the swab bits in an asm file and then the includes can be cleaned up without requiring a flag day for all arches at once. Keep providing __fswabXX in case some userspace was using them directly, but the revised __swabXX should be used instead in any new code and will always do constant folding not dependent on the optimization level, which means the __constant versions can be phased out in-kernel. Arches that use the old-style arch macros will lose their optimized versions until they move to the new style, but at least they will still compile. Many arches have already moved and the patches to move the remaining arches are trivial. Signed-off-by:
