2014-05-21hwmon: (max1619) Fix critical alarm displayGuenter Roeck1-0/+5
The overtemperature status bit, which is used to display critical alarm status, matches the output of the OVERT signal 1:1. If that signal is active-low, the bit will read 1 if there is no alarm. It is therefore necessary to reverse the bit in this case. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2014-05-21hwmon: (lm77) Do not preserve hysteresis when updating critical temp limitGuenter Roeck1-6/+0
Updating the hysteresis value when updating the critical temperature limit was following the rule of 'least surprise'. However, it had the undesirable side effect of changing the hysteresis for all other attributes, which defeats the purpose of least surprise. In addition, it could result in invalid hysteresis values if the resulting hysteresis was too large. In such cases the resulting hysteresis ended up changed anyway, which again defeats the purpose. So drop that code and document the new behavior. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2014-05-15mfd: vexpress: Convert custom func API to regmapPawel Moll1-10/+7
Components of the Versatile Express platform (configuration microcontrollers on motherboard and daughterboards in particular) talk to each other over a custom configuration bus. They provide miscellaneous functions (from clock generator control to energy sensors) which are represented as platform devices (and Device Tree nodes). The transactions on the bus can be generated by different "bridges" in the system, some of which are universal for the whole platform (for the price of high transfer latencies), others restricted to a subsystem (but much faster). Until now drivers for such functions were using custom "func" API, which is being replaced in this patch by regmap calls. This required: * a rework (and move to drivers/bus directory, as suggested by Samuel and Arnd) of the config bus core, which is much simpler now and uses device model infrastructure (class) to keep track of the bridges; non-DT case (soon to be retired anyway) is simply covered by a special device registration function * the new config-bus driver also takes over device population, so there is no need for special matching table for of_platform_populate nor "simple-bus" hack in the arm64 model dtsi file (relevant bindings documentation has been updated); this allows all the vexpress devices fit into normal device model, making it possible to remove plenty of early inits and other hacks in the near future * adaptation of the syscfg bridge implementation in the sysreg driver, again making it much simpler; there is a special case of the "energy" function spanning two registers, where they should be both defined in the tree now, but backward compatibility is maintained in the code * modification of the relevant drivers: * hwmon - just a straight-forward API change * power/reset driver - API change * regulator - API change plus error handling simplification * osc clock driver - this one required larger rework in order to turn in into a standard platform driver Signed-off-by: Pawel Moll <pawel.moll@arm.com> Acked-by: Mark Brown <broonie@linaro.org> Acked-by: Lee Jones <lee.jones@linaro.org> Acked-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Mike Turquette <mturquette@linaro.org>

2014-05-12hwmon: (emc1403) Fix resource leak on module unloadJean Delvare1-3/+3
Commit 454aee17f claims to convert driver emc1403 to use devm_hwmon_device_register_with_groups, however the patch itself makes use of hwmon_device_register_with_groups instead. As the driver remove function was still dropped, the hwmon device is no longer unregistered on driver removal, leading to a resource leak.
