2019-01-22regulator: qcom-smd: Batch up requests for disabled regulatorsBjorn Andersson
In some scenarios the early stages of the boot chain has configured regulators to be in a required state, but the later stages has skipped to inform the RPM about it's requirements. But as the SMD RPM regulators are being initialized voltage change requests will be issued to align the voltage with the valid ranges. The RPM aggregates all parameters for the specific regulator, the voltage will be adjusted and the "enabled" state will be "off" - and the regulator is turned off. This patch addresses this problem by caching the requested enable state, voltage and load and send the parameters in a batch, depending on the enable state - effectively delaying the voltage request for disabled regulators.

2016-08-05regulator: qcom_smd: Fix voltage ranges for pma8084 ftsmps and pldoStephen Boyd
The voltage ranges listed here are wrong. The pma8084 pldo supports three different overlapping voltage ranges with differing step sizes and the pma8084 ftsmps supports two. These ranges can be seen in the "native" spmi regulator driver (qcom_spmi-regulator.c) at pldo_ranges[] and ftsmps_ranges[] respectively. Port these ranges over to the RPM SMD regulator driver so that we list the appropriate set of supported voltages on these types of regulators.

The voltage ranges listed here are wrong. The correct ranges can be seen in the "native" spmi regulator driver qcom_spmi-regulator.c at pldo_ranges[], ftsmps_ranges[] and boost_ranges[] for the pldo, ftsmps, and boost type regulators. Port these ranges over to the RPM SMD regulator driver so that we list the appropriate set of supported voltages on pldos. Doing this allows us to specify a voltage like 3075000 for l24, whereas before that wasn't a supported voltage.

2016-07-12regulator: qcom_smd: Avoid overlapping linear voltage rangesStephen Boyd
The pm8x41_hfsmps ranges overlap. The first range is from 375000 to 1562500: 375000 + (95 * 12500) == 1562500 and the second range starts at 1550000. Interestingly, the second range ends at the correct value when it's set to be the appropriate start value, 1575000: 1575000 + ((158 - 96) * 25000) == 3125000 Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Reviewed-by: Andy Gross <andy.gross@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-06-15regulator: qcom_smd: Remove list_voltage callback for rpm_smps_ldo_ops_fixedAxel Lin
Use regulator_list_voltage_linear_range in rpm_smps_ldo_ops_fixed is wrong because it is used for fixed regulator without any linear range. The rpm_smps_ldo_ops_fixed is used for pm8941_lnldo which has fixed_uV set and n_voltages = 1. In this case, regulator_list_voltage() can return rdev->desc->fixed_uV without .list_voltage implementation.
