During regulator registration, the voltage variable is just declared and it is zero. Based on that, the regulator framework considers current the voltage as zero and tries to bring up each regulator to minimum the supported voltage. This introduces a dip in the voltage during kernel boot and gets stabilized once the voltage scaling comes into picture. To avoid the voltage dip, adding support to define the bootup voltage set by the boodloaders and based on it, regulator framework understands that proper voltage is already set Co-developed-by: Praveenkumar I Signed-off-by: Praveenkumar I Signed-off-by: devi priya --- drivers/regulator/qcom_smd-regulator.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/drivers/regulator/qcom_smd-regulator.c b/drivers/regulator/qcom_smd-regulator.c index 1eb17d378897..49a36b07397c 100644 --- a/drivers/regulator/qcom_smd-regulator.c +++ b/drivers/regulator/qcom_smd-regulator.c @@ -800,6 +800,7 @@ struct rpm_regulator_data { u32 id; const struct regulator_desc *desc; const char *supply; + int boot_uV; /* To store the bootup voltage set by bootloaders */ }; static const struct rpm_regulator_data rpm_mp5496_regulators[] = { @@ -809,7 +810,7 @@ static const struct rpm_regulator_data rpm_mp5496_regulators[] = { }; static const struct rpm_regulator_data rpm_ipq9574_mp5496_regulators[] = { - { "s1", QCOM_SMD_RPM_SMPA, 1, &ipq9574_mp5496_smpa1, "s1" }, + { "s1", QCOM_SMD_RPM_SMPA, 1, &ipq9574_mp5496_smpa1, "s1", 875000 }, {} }; @@ -1394,6 +1395,9 @@ static int rpm_regulator_init_vreg(struct qcom_rpm_reg *vreg, struct device *dev vreg->type = rpm_data->type; vreg->id = rpm_data->id; + if (rpm_data->boot_uV) + vreg->uV = rpm_data->boot_uV; + memcpy(&vreg->desc, rpm_data->desc, sizeof(vreg->desc)); vreg->desc.name = rpm_data->name; vreg->desc.supply_name = rpm_data->supply;
