Changes in V2:
- Moved this patch before "mfd: pm8008: Add pm8008 regulator node" to
resolve dtschema errors. Removed regulator-min-microvolt and
regulator-max-microvolt properties.
Changes in V3:
- As per Rob's comments added standard unit suffix for mindropout property,
added blank lines where required and added description for reg property.
Changes in V4:
- Changed compatible string to "com,pm8008-regulators"
- Moved "regulator-min-dropout-voltage-microvolt" to regulator.yaml as
separate patch.
Changes in V5:
- Removed the separate compatible for pm8008 regulator driver.
- Moved the supply nodes to chip level.
- Removed min-dropout property.
Changes in V6:
- Changed regulator node names to small letters.
- Changed regulator-name property to optional.

Shouldn't interrupts and interrupt-cells still be required for
qcom,pm8008? This binding seems like it is for two different nodes.

No, these are not strictly required.

This binding is for the same node with different SIDs 8 and 9, having

Register mfd cell ID and name for each of the 7 pm8008
LDOs to probe them through mfd driver without needing
a separate compatible for regulator driver.
Also, add a different compatible for the mfd node that
contains regulators to make sure that the LDOs are
registered with the correct mfd device.
Signed-off-by: Satya Priya <quic_c_skakit@quicinc.com>
---
Changes in V5:
- Changes newly added from V5.
Changes in V6:
- Changed the mfd_cell struct to have only name of the regulator driver.
- Using device_get_match_data() instead of of_match_node() to match data.
- Fixed few nits.

Qualcomm Technologies, Inc. PM8008 is an I2C controlled PMIC
containing 7 LDO regulators. Add a PM8008 regulator driver to
support PMIC regulator management via the regulator framework.
Signed-off-by: Satya Priya <quic_c_skakit@quicinc.com>
---
Changes in V2:
As per Mark's comments
- Using regmap helpers for regulator enable/disable and is_enabled APIs
- Changed pr_err to dev_err wherever possible.
- Removed init_voltage property as it is not used.
- Removed if check for registering LDOs
- Other minor changes.
Changes in V3:
As per Stephen's comments,
- Removed unused includes
- Removed PM8008_MAX_LDO macro.
- Removed pm8008_read/write APIs, using regmap_bulk_read/write APIs
- Using le16_to_cpu/cpu_to_le16 APIs in pm8008_regulator_get/set_voltage
- Consolidated all probe related functions into single probe function.
- Added of_parse_cb call back and removed regulator-name matching loop.
- Fixed other minor nits.
Changes in V4:
- Removed unused members like rdev and of_node from pm8008_regulator struct.
- Replaced set_voltage with set_voltage_sel
- Removed init_data configuration as it is not needed.
- Removed few other unused assignments from probe
Changes in V5:
- Removed Compatible string.
- Changed the probe function accordingly to probe LDOs using mfd driver.
- Added max headrooms for LDOs and removed the part reading min-dropout from DT.
- Added base reg values in the regulator_data struct instead of reading it from DT.
Changes in V6:
- Using loop to probe the regulators instead of creating separate platform device for
each regulator.
- Removed the of_parse_cb API as we are not parsing any DT properties. Moved slewrate
configuration to probe.
- Fixed other nits.

Add base DTS file for pm8008 with infra and regulator nodes.
Signed-off-by: Satya Priya <quic_c_skakit@quicinc.com>
---
Changes in V4:
- This is newly added in V4, to add all the pm8008 common stuff.
Changes in V5:
- Changed the mfd node names from pm8008_chip to pm8008_infra and
pm8008_ldo to pm8008_regulators as they re more appropriate.
- Changed the compatible for pm8008@9 mfd node to differentiate from
pm8008@8 node in driver.
- Removed compatible for regulators node.
- Removed reg property for LDOs and added in driver.
Changes in V6:
- Changed node names to small letters.

Add pm8008_infra and pm8008_regulators support for sc7280 idp.
Signed-off-by: Satya Priya <quic_c_skakit@quicinc.com>
---
Changes in V2:
- As per Stephen's comments, replaced '_' with '-' for node names.
Changes in V3:
- Changed the regulator node names as l1, l2 etc
- Changed "pm8008-regulators" to "regulators"
- Changed "qcom,min-dropout-voltage" to "regulator-min-dropout-voltage-microvolt"
Changes in V4:
- Moved all common stuff to pm8008.dtsi and added board specific configurations here.
Changes in V5:
- Changed the node names as per pm8008.dtsi
- Moved supply nodes to chip level (mfd node).
- Removed the regulator-mindropout property.
Changes in V6:
- No changes.
