+ * Setups where regulator (especially the buck8) output voltage is scaled
+ * by adding external connection where some other regulator output is connected
+ * to feedback-pin (over suitable resistors) is getting popular amongst users
+ * of BD71837. (This allows for example scaling down the buck8 voltages to suit
+ * lover GPU voltages for projects where buck8 is (ab)used to supply power
+ * for GPU. Additionally some setups do allow DVS for buck8 but as this do
+ * produce voltage spikes the HW must be evaluated to be able to survive this
+ * - hence I keep the DVS disabled for non DVS bucks by default. I don't want
+ * to help you burn your proto board)
+ *
+ * So we allow describing this external connection from DT and scale the
+ * voltages accordingly. This is what the connection should look like:
+ *
+ * |------------|
+ * |	buck 8  |-------+----->Vout
+ * |		|	|
+ * |------------|	|
+ *	| FB pin	|
+ *	|		|
+ *	+-------+--R2---+
+ *		|
+ *		R1
+ *		|
+ *	V FB-pull-up
+ *
+ *	Here the buck output is sifted according to formula:
+ *
+ * Vout_o = Vo - (Vpu - Vo)*R2/R1
+ * Linear_step = step_orig*(R1+R2)/R1
+ *
+ * where:
+ * Vout_o is adjusted voltage output at vsel reg value 0
+ * Vo is original voltage output at vsel reg value 0
+ * Vpu is the pull-up voltage V FB-pull-up in the picture
+ * R1 and R2 are resistor values.
+ *
+ * As a real world example for buck8 and a specific GPU:
+ * VLDO = 1.6V (used as FB-pull-up)
+ * R1 = 1000ohms
+ * R2 = 150ohms
+ * VSEL 0x0 => 0.8V – (VLDO – 0.8) * R2 / R1 = 0.68V
+ * Linear Step = 10mV * (R1 + R2) / R1 = 11.5mV
