Add SW support for the vibrator module inside PMI632, PM7250B, PM7325B, PM7550BA.
It is very similar to the vibrator module inside PM8916 which is supported in
pm8xxx-vib driver but just the drive amplitude is controlled with 2 registers,
and the register base offset in each PMIC is different.
Changes in v10:
1. Add Fixes tag
2. Update SSBI vibrator to use DT 'reg' value
3. Add drv_in_step flag for programming vibrator level in steps
Link to v9: https://lore.kernel.org/r/20240411-pm8xxx-vibrator-new-design-v9-0-7bf56cb92b28@xxxxxxxxxxx
Changes in v9:
1. Add a preceding change to correct VIB_MAX_LEVELS calculation
2. Address review comments from Konrad
Link to v8: https://lore.kernel.org/r/20240401-pm8xxx-vibrator-new-design-v8-0-6f2b8b03b4c7@xxxxxxxxxxx
Changes in v8:
1. Remove hw_type, and still keep the register info in match data
2. Update to use register offset in pm8xxx_regs, and the base address
defined in DT for SPMI vibrator will be added in register access
3. Update voltage output range for SPMI vibrator which has 2 bytes drive
registers
Changes in v7:
1. Fix a typo: SSBL_VIB_DRV_REG --> SSBI_VIB_DRV_REG
2. Move the hw_type switch case in pm8xxx_vib_set() to the refactoring
change.
Changes in v6:
1. Add "qcom,pmi632-vib" as a standalone compatible string.
Changes in v5:
1. Drop "qcom,spmi-vib-gen2" generic compatible string as requested
and use device specific compatible strings only.
Changes in v4:
1. Update to use the combination of the HW type and register offset
as the constant match data, the register base address defined in
'reg' property will be added when accessing SPMI registers using
regmap APIs.
2. Remove 'qcom,spmi-vib-gen1' generic compatible string.
Changes in v3:
1. Refactor the driver to support different type of the vibrators with
better flexibility by introducing the HW type with corresponding
register fields definitions.
2. Add 'qcom,spmi-vib-gen1' and 'qcom,spmi-vib-gen2' compatible
strings, and add PMI632, PM7250B, PM7325B, PM7550BA as compatbile as
spmi-vib-gen2.
Changes in v2:
Remove the "pm7550ba-vib" compatible string as it's compatible with pm7325b.
