|\ | | | | | | | | | | | | Merge series from Stephan Gerhold <stephan.gerhold@kernkonzept.com>: Fix the voltage range for the pm8916_pldo in the qcom_smd-regulator driver and add definitions for the regulators available in PM8909.
| * regulator: qcom_smd: Add PM8909 RPM regulatorsStephan Gerhold2022-06-291-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The set of regulators available in the PM8909 PMIC is similar to PM8916 which is already supported by the driver. s3, s4 and l16 are missing. However, probing the SPMI hardware identification registers using the qcom_spmi-regulator driver reveals that the regulators in PM8909 are actually some kind of mixture between PM8916 and PM8226: - ult_lo_smps (= pm8916_buck_lvo_smps): s1 - ult_ho_smps (= pm8916_buck_hvo_smps): s2 - ult_nldo (= pm8916_nldo): l1, l2, l3, l10 - ult_pldo (= pm8916_pldo): l4, l8, l9, l12-l15, l17, l18 - pldo (= pm8226_pldo): l5, l6, l7, l11 Use this mapping to add the rpm_regulator_data for PM8909 by reusing the existing regulator definitions.

| * regulator: qcom_smd: Fix pm8916_pldo rangeStephan Gerhold2022-06-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PM8916 device specification [1] documents a programmable range of 1.75V to 3.337V with 12.5mV steps for the PMOS LDOs in PM8916. This range is also used when controlling the regulator directly using the qcom_spmi-regulator driver ("ult_pldo" there). However, for some reason the qcom_smd-regulator driver allows a much larger range for the same hardware component. This could be simply a typo, since the start of the range is essentially just missing a '1'. In practice this does not cause any major problems, since the driver just sends the actual voltage to the RPM firmware instead of making use of the incorrect voltage selector. Still, having the wrong range there is confusing and prevents the regulator core from validating requests correctly.

| | | | | | | | | | | | | | | | | | | | | | | The RPMh regulator driver is much newer and gets more attention, which in consequence makes it do a few things better. Update qcom_smd-regulator's probe function to mimic what rpmh-regulator does to address a couple of issues: - Probe defer now works correctly, before it used to, well, kinda just die.. This fixes reliable probing on (at least) PM8994, because Linux apparently cannot deal with supply map dependencies yet.. - Regulator data is now matched more sanely: regulator data is matched against each individual regulator node name and throwing an -EINVAL if data is missing, instead of just assuming everything is fine and iterating over all subsequent array members. - status = "disabled" will now work for disabling individual regulators in DT. Previously it didn't seem to do much if anything at all.

* regulator: qcom-smd: Batch up requests for disabled regulatorsBjorn Andersson2019-01-221-35/+69
| | | | | | | | | | | | | | | | | | | | 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.

* regulator: qcom_smd: add regulator ops for pm8941 lnldoSrinivas Kandagatla2016-06-081-1/+12
| | | | | | | | | | | | After "regulator: qcom_smd: add list_voltage callback" patch adding pm8941 lnldo regulators would bug on list_voltages as it is a fixed regulator without any linear range. This patch fixes that issue by adding dedicated ops for pm8941 lnldo without list_voltages callback.

| | | | | | | | | | The smd rpm structures are always in little endian, but this driver is not capable of being used on big endian CPUs. Annotate the little endian data members and update the code to do the proper byte swapping. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Mark Brown <broonie@kernel.org>

| | | | | | | | | Just setting fixed_uV is not enough, the regulator core will also check n_voltages setting. The fixed_uV only works when n_voltages is 1.
