Subject[PATCH v3 0/3] TPS68470 PMIC drivers
Date
This is the patch series for TPS68470 PMIC that works as a camera PMIC.

The patch series provide the following 3 drivers, to help configure
the voltage regulators, clocks and GPIOs provided by the TPS68470
PMIC, to be able to use the camera sensors connected to this PMIC.

TPS68470 MFD driver:
This is the multi function driver that initializes the TPS68470
PMIC and supports the GPIO and Op Region functions.

TPS68470 GPIO driver:
This is the PMIC GPIO driver that will be used by the OS GPIO layer,
when the BIOS / firmware triggered GPIO access is done.

TPS68470 Op Region driver:
This is the driver that will be invoked, when the BIOS / firmware
configures the voltage / clock for the sensors / vcm devices
connected to the PMIC.

Changes in v3:
- MFD driver:
- Removed GPIO lookup table
- Reverted to probe() for consistency
- Addressed other comments from Andy

- GPIO driver:
- Removed the code that initializes the default values
of GPIOs to zeros
- Used gpiochip_get_data() to access data inside the gpio_chip

Changes in v2:
- MFD driver:
- Removed tps68470_* wrappers around regmap_* calls
- Removed "struct tps68470"
- used devm_mfd_add_devices and removed mutex in mfd driver
- Added reasoning about the need of having mfd driver
as bool/builtin

- Opregion driver:
- renamed opregion driver file / internal symbol names
with tps68470_pmic*
- Made opregion driver tables as const
- Removed unused *handler_context in common handler
- Replaced "int" with "unsigned int"
- Changed to WARN macro to dev_warn()
- Destroyed mutex on error
- Added reasoning about the need of having Opregion driver
as bool/builtin

- GPIO driver:
- Implemented get_direction() in the GPIO driver
- Setup gpio_chip.names
- Moved the GPIO lookup table code inside mfd driver
- Added reasoning about the need of having GPIO driver
as bool/builtin
