2013-02-11regulator: palmas: implement errata for ES1.0,ES2.0 and ES2.1Laxman Dewangan
The device has the errata and sw need to implement the WAR for proper functioning of the device. The errata are: 1. SMPS- slew rate (TSTEP) is slower than expected ----------------------------------------------- when output voltage target is close to previous one IMPACT: The settling time is greater than specified slew rate in register map and datasheet for voltage scaling of the SMPS. DESCRIPTION: Measurement done on WCSP ES2.0, SMPS8, SMPS6, SMPS12 for TSTEP=0x02(5mV/us) - step from VOUT= 0.5v to 1.65V ==>slew rate is around 5mV/us - step from VOUT= 0.96v to 1.04V ==>slew rate is around 2.5mV/us for TSTEP=0x03(2.5mV/us) - step from VOUT= 0.5v to 1.65V ==>slew rate is around 2.5mV/us - step from VOUT= 0.96v to 1.04V ==>slew rate is around 1.6mV/us WORKAROUND: Adapt wait time using above value. REVISION IMPACTED: ES1.0/ES2.0/ES2.1 2. LDO8_TRACKING: PD in tracking mode ------------------------------------- IMPACT: Higher consumption and performance impact when LDO8 is set in tracking mode and LDO is set to have its pull down enabled in OFF mode. DESCRIPTION: When LDO8 is set in tracking mode and the LDO is set to have its pull down enabled in OFF, the pull down is also enabled in ACTIVE mode. WORKAROUND: In tracking mode, bit7 of LDO_PD_CTRL1 register must be set to 0. When LDO8 is disabled, to have the pull down, bit7 of LDO_PD_CTRL1 register must then be set to 1. In LDO8 regulation mode, behavior is the same as the other LDOs.

2012-09-14regulator: twl-regulator: fix up VINTANA1/VINTANA2Aaro Koskinen
commit 908d6d52928a7f2a4b317aac47542c5fbef43d88 upstream. It seems commit 2098e95ce9bb039ff2e7bf836df358d18a176139 (regulator: twl: adapt twl-regulator driver to dt) accidentally deleted VINTANA1. Also the same commit defines VINTANA2 twice with TWL4030_ADJUSTABLE_LDO and TWL4030_FIXED_LDO. This patch changes the fixed one to be VINTANA1. I noticed this when auditing my N900 boot logs. I could not notice any change in device behaviour, though, except that the boot logs are now like before: ... [ 0.282928] VDAC: 1800 mV normal standby [ 0.284027] VCSI: 1800 mV normal standby [ 0.285400] VINTANA1: 1500 mV normal standby [ 0.286865] VINTANA2: 2750 mV normal standby [ 0.288208] VINTDIG: 1500 mV normal standby [ 0.289978] VSDI_CSI: 1800 mV normal standby ...
