2013-09-27regulator: ti-abb: Fix bias voltage glitch in transition to bypass modeNishanth Menon1-2/+14
As documented in Application Note SWPA117 v2.1(NDA), LDO override has a requirement that when switching from Bias active + override active mode(FBB/RBB) to Bypass(nominal) mode, LDO reset must be performed *after* LDO transitions to Bypass(nominal) mode. The same rule in reverse applies when switching from a ABB bypass mode to ABB enabled - LDO override *must* be performed prior to transition to required ABB mode, if we do not do that, the same glitch takes place. Currently while transitioning to ABB bypass, we reset the LDO overide prior to the transition which causes a few milliseconds where ABB LDO voltage could go all the way to 800mV(based on SoC process node), during this period, the delta voltage between VDD rail and VBB rail could cause the system to improperly function.

2013-09-23regulator: wm831x-ldo: Fix max_uV for gp_ldo and aldo linear range settingsAxel Lin1-2/+2
Fix the linear range settings in commit 5ff26a14c3331 "regulator: wm831x-ldo: Convert to use linear ranges". For wm831x_gp_ldo: We have below equations for list voltage before converting to linear ranges: sel <= 0xe: volt = 0.9-1.6V in 50mV steps sel <= 0x1f: volt = 1.7-3.3V in 100mV steps max_uV for the first linear range should be 1600000 rather than 1650000. Fix it. For wm831x_aldo: We have below equations for list voltage before converting to linear ranges: sel <= 0xc: volt = 1-1.6V in 50mV steps sel <= 0x1f volt = 1.7-3.5V in 100mV steps max_uV for the first linear range should be 1600000 rather than 1650000.

As per datasheet, voltage range for LDOs are as follows: 0000 = 0.9V ...(50mV steps) 01111 = 1.65V 10000 = 1.8V ... (100mV stepns) 11111 = 3.3V So, there is no selector for 1.65V to 1.8V.

num_voltages Current equation on the comment is wrong. For linear mapping starting from 0, the equation is (maxV-minV)/stepV + 1. Since the linear mapping for PALMAS is not all starting from 0, the equation on the comment is not useful and misleading. Thus remove it.

With the following change --------- commit ad02e846878ca35e9d3fa584be8ee770e9e14fce Author: Axel Lin <axel.lin@ingics.com> 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.

Below is the equation in original code: tps65217_uv1_ranges: 0 ... 24: uV = vsel * 25000 + 900000; 25 ... 52: uV = (vsel - 24) * 50000 + 1500000; = (vsel - 25) * 50000 + 1550000; 53 ... 55: uV = (vsel - 52) * 100000 + 2900000; = (vsel - 53) * 100000 + 3000000; 56 ... 62: uV = 3300000; tps65217_uv2_ranges: 0 ... 8: uV = vsel * 50000 + 1500000; 9 ... 13: uV = (vsel - 8) * 100000 + 1900000; = (vsel - 9) * 100000 + 2000000; 14 ... 31: uV = (vsel - 13) * 50000 + 2400000; = (vsel - 14) * 50000 + 2450000; The voltage tables are composed of linear ranges. This patch converts this driver to use multiple linear ranges APIs. In original code, voltage range for DCDC1 is 900000 ~ 1800000 and voltage range for DCDC3 is 900000 ~ 1500000. This patch separates the range 25~52 in tps65217_uv1_ranges table to two linear ranges: 25~30 and 31~52. This change makes it possible to reuse the same linear_ranges table for DCDCx.

2013-08-29regulator: da9063: Add Dialog DA9063 voltage regulators support.Krystian Garbaciak3-0/+952
The driver adds support for the following DA9063 PMIC regulators: - 11x LDOs (named LDO1 - LDO11), - 6x buck converters (BCORE1, BCORE2, BPRO, BMEM, BIO, BPERI), Regulators provide following operations: - REGULATOR_CHANGE_STATUS and REGULATOR_CHANGE_VOLTAGE for all regulators, - REGULATOR_CHANGE_MODE for LDOs and buck converters, where: - LDOs allow REGULATOR_MODE_NORMAL and REGULATOR_MODE_STANDBY, - buck converters allow REGULATOR_MODE_FAST, REGULATOR_MODE_NORMAL and REGULATOR_MODE_STANDBY, - REGULATOR_CHANGE_CURRENT for buck converters (current limits). The driver generates REGULATOR_EVENT_OVER_CURRENT for LDO3, LDO4, LDO7, LDO8 and LDO11. Internally, PMIC provides two voltage configurations for normal and suspend system state for each regulator. The driver switches between those on suspend/wake-up to provide quick and fluent output voltage change. This driver requires MFD core driver for operation.
