This patch is partially based on Felipe Contrera's earlier patch, that was discussed here: https://lkml.org/lkml/2013/10/8/800 Some problems of that patch are solved, now: 1) The main obstacle for the earlier patch seemed to be the use of virt_to_phys, which is accepted, now 2) random memory corruption occurred on my notebook, thus DMA-able memory is allocated now, which solves this problem 3) hwmon interface is used instead of the thermal interface, as a hwmon device is already set up by this driver and seemed more appropriate than the thermal interface 4) Calling the ACPI-functions was modularized thus it's possible to call some multifunctions easily, now (by using asus_wmi_evaluate_method_agfn). Unfortunately the WMI doesn't support controlling both fans on a dual-fan notebook because of an restriction in the acpi-method "SFNS", that is callable through the wmi. If "SFNV" would be called directly even dual fan configurations could be controlled, but not by using wmi. Speed readings only work on auto-mode, thus "-1" will be reported in manual mode. Additionally the speed readings are reported as hundreds of RPM thus they are not too precise. This patch is tested only on one notebook (N551JK) but a similar module, that contained some code to try to control the second fan also, was reported to work on an UX32VD, at least for the first fan. As Felipe already mentioned the low-level functions are described here: http://forum.notebookreview.com/threads/fan-control-on-asus-prime-ux31-ux31a-ux32a-ux32vd.705656/ Signed-off-by: Kast Bernd <kastbernd@gmx.de> Acked-by: Corentin Chary <corentin.chary@gmail.com> Cc: Corentin Chary <corentin.chary@gmail.com> Cc: Darren Hart <dvhart@infradead.org> Cc: Matthew Garrett <mjg59@srcf.ucam.org> Cc: Rafael J.
