+ * Windfarm PowerMac thermal control. iMac G5 iSight
+ *
+ * (c) Copyright 2007 Étienne Bersac <bersace@gmail.com>
+ *
+ * Bits & pieces from windfarm_pm81.c by (c) Copyright 2005 Benjamin
+ * Herrenschmidt, IBM Corp. <benh@kernel.crashing.org>
+ *
+ * Released under the term of the GNU GPL v2.
+ *
+ *
+ *
+ * PowerMac12,1
+ * ============
+ *
+ *
+ * The algorithm used is the PID control algorithm, used the same way
+ * the published Darwin code does, using the same values that are
+ * present in the Darwin 8.10 snapshot property lists (note however
+ * that none of the code has been re-used, it's a complete
+ * re-implementation
+ *
+ * There is two models using PowerMac12,1. Model 2 is iMac G5 iSight
+ * 17" while Model 3 is iMac G5 20". They do have both the same
+ * controls with a tiny difference. The control-ids of hard-drive-fan
+ * and cpu-fan is swapped.
+ *
+ *
+ * Target Correction :
+ *
+ * controls have a target correction calculated as :
+ *
+ * new_min = ((((average_power * slope) >> 16) + offset) >> 16) + min_value
+ * new_value = max(new_value, max(new_min, 0))
+ *
+ * OD Fan control correction.
+ *
+ * # model_id: 2
+ * offset : -19563152
+ * slope : 1956315
+ *
+ * # model_id: 3
+ * offset : -15650652
+ * slope : 1565065
+ *
+ * HD Fan control correction.
+ *
+ * # model_id: 2
+ * offset : -15650652
+ * slope : 1565065
+ *
+ * # model_id: 3
+ * offset : -19563152
+ * slope : 1956315
+ *
+ * CPU Fan control correction.
+ *
+ * # model_id: 2
+ * offset : -25431900
+ * slope : 2543190
+ *
+ * # model_id: 3
+ * offset : -15650652
+ * slope : 1565065
+ *
+ *
+ * Target rubber-banding :
+ *
+ * Some controls have a target correction which depends on another
+ * control value. The correction is computed in the following way :
+ *
+ * new_min = ref_value * slope + offset
+ *
+ * ref_value is the value of the reference control. If new_min is
+ * greater than 0, then we correct the target value using :
+ *
+ * new_target = max (new_target, new_min >> 16)
+ *
+ *
+ * # model_id : 2
+ * control : cpu-fan
+ * ref : optical-drive-fan
+ * offset : -15650652
+ * slope : 1565065
+ *
+ * # model_id : 3
+ * control : optical-drive-fan
+ * ref : hard-drive-fan
+ * offset : -32768000
+ * slope : 65536
+ *
+ *
+ * In order to have the moste efficient correction with those
+ * dependencies, we must trigger HD loop before OD loop before CPU
+ * loop.
+ *
+ *
+ * The various control loops found in Darwin config file are:
+ *
