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 --- Changes in V2: - Added the bootup voltages to s2 and l2 regulators drivers/regulator/qcom_smd-regulator.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/drivers/regulator/qcom_smd-regulator.c b/drivers/regulator/qcom_smd-regulator.c index a40e66cea7e7..5f9fe6b9d368 100644 --- a/drivers/regulator/qcom_smd-regulator.c +++ b/drivers/regulator/qcom_smd-regulator.c @@ -800,12 +800,13 @@ struct rpm_regulator_data { u32 id;
