hi Laxman,
Currently we have below code in tps80031_ldo_set_voltage_sel():
/* Check for valid setting for TPS80031 or TPS80032-ES1.0 */
if ((ri->rinfo->desc.id == TPS80031_REGULATOR_LDO2) &&
(ri->device_flags & TRACK_MODE_ENABLE)) {
unsigned nvsel = (sel) & 0x1F;
if (((tps80031_get_chip_info(parent) == TPS80031) ||
((tps80031_get_chip_info(parent) == TPS80032) &&
(tps80031_get_pmu_version(parent) == 0x0))) &&
((nvsel == 0x0) || (nvsel >= 0x19 && nvsel <= 0x1F))) {
dev_err(ri->dev,
"Invalid sel %d in track mode LDO2\n",
nvsel);
return -EINVAL;
}
}
However, list_voltage() still show these invalid selectors have supported
voltage.
Besides, having the code "nvsel = (sel) & 0x1F" looks a bit odd, because
currently
n_voltages is set to 57 when TRACK_MODE_ENABLE is set.
I'm wondering if below comment is still true for LDO2 TRACK_MODE_ENABLE of
"TPS80031/TPS80032-ES1.0"?
/* TRACK mode the ldo2 varies from 600mV to 1300mV */
What is the register value && voltage mapping for LDO2 TRACK_MODE_ENABLE of
TPS80031 or TPS80032-ES1.0?
Regards,
Axel
