From 0f45aa84b33b7a9bfeb41845c723dc51f82f1cf0 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Wed, 4 Sep 2013 15:20:06 +0530 Subject: regulator: palmas: fix the n_voltages for smps to 122 With the following change --------- commit ad02e846878ca35e9d3fa584be8ee770e9e14fce Author: Axel Lin regulator: palmas: Return raw register values as the selectors in [get|set]_voltage_sel Don't adjust the selector in [get|set]_voltage_sel, fix it in list_voltage() instead. For smps*(except smps10), the vsel reg-value and voltage mapping as below: ---------- The list_voltage() takes the true value of selector which is programmed in the register. As per smsp voltage table reg-value volt (uV) ( Assume RANGE is x1 ) 0 0 1 500000 2 500000 3 500000 4 500000 5 500000 6 500000 (0.49V + 1 * 0.01V) * RANGE 7 510000 (0.49V + 2 * 0.01V) * RANGE 8 520000 (0.49V + 3 * 0.01V) * RANGE 9 530000 (0.49V + 4 * 0.01V) * RANGE .... 121 1650000 (0.49V + 116 * 0.1) * RANGE Hence making n_voltages for smps to 122.
