[v5,0/5] Add TI TPS65214 & TPS65215 PMIC MFD Driver Support

Message

TPS65214 and TPS65215 are Power Management Integrated Circuits (PMICs) that
have significant register map overlap with TPS65219 and each other. The 
series introduces the 2 new PMICs and restructures the existing driver to 
support multiple devices.

- TPS65214, TPS65215, and TPS65219 each have 3 Buck regulators
- TPS65214 has 2 LDOS and 1 GPO, whereas TPS65219 has 4 LDOs and 2 GPOs.
- TPS65214's LDO1 maps to TPS65219's LDO3.
- A key difference between TPS65215 & TPS65214 are the LDO current and
  voltage output ranges and the configurable options available.
- TPS65215 has 2 LDOs, whereas TPS65219 has 4 LDOs.
- TPS65215's LDO2 maps to TPS65219's LDO3.
- TPS65215 has 1 GPO, whereas TPS65219 has 2 GPOs.

Change Log:
v4 -> v5:
- TPS65214 dt-binding patch: Remove duplicated "then:", combine "if:" 
  statements with enum.
v3 -> v4:
- Update commit header to be "mfd: tps65219" since the driver name has not 
  been changed from TPS65219.
- Added dt-bindings patches to mfd series.
- Combined TPS65214 & TPS65215 dt-binding and mfd patches into 1 series, 
  since the series' share a dependency & these patches add more device support
- Elimate the need for TPS65214 gpio patches by registering TPS65214 as 
  "tps65215-gpio" from the MFD driver, since both have the same GPIO module
- "Remove regmap_read" patch: Drop chip_id variable
- move enum pmic_id struct from "remove regmap_read" patch to "Add support 
  for TPS65215" patch.
v2 -> v3:
- Remove duplicated of_device_id table entries
- Re-order mfd patches to clean up diff displayed
v1 -> v2:
- have any PMIC lists be in alpha-numeric order: TPS65215, then TPS65219
- Add driver prefix to chip_data struct
