[PATCH v2 00/14] Add support for TI TPS65224 PMIC

[PATCH v2 00/14] Add support for TI TPS65224 PMIC

[Bhargav Raviprakash]

This series modifies the existing TPS6594 drivers to add support for the
TPS65224 PMIC device that is a derivative of TPS6594. TPS65224 has a
similar register map to TPS6594 with a few differences. SPI, I2C, ESM,
PFSM, Regulators and GPIO features overlap between the two devices.

TPS65224 is a Power Management IC (PMIC) which provides regulators and
other features like GPIOs, Watchdog, Error Signal Monitor (ESM) and
Pre-configurable Finite State Machine (PFSM). The SoC and the PMIC can
communicate through the I2C or SPI interfaces. The PMIC TPS65224
additionally has a 12-bit ADC.
Data Sheet for TPS65224: https://www.ti.com/product/TPS65224-Q1

Driver re-use is applied following the advice of the following series:
https://lore.kernel.org/lkml/2f467b0a-1d11-4ec7-8ca6-6c4ba66e5887@baylibre.com/

The features implemented in this series are:
- TPS65224 Register definitions
- Core (MFD I2C and SPI entry points)
- PFSM	
- ESM
- Regulators
- Pinctrl

TPS65224 Register definitions:
This patch adds macros for register field definitions of TPS65224
to the existing TPS6594 driver.  

Core description:
I2C and SPI interface protocols are implemented, with and without
the bit-integrity error detection feature (CRC mode).

PFSM description:
Strictly speaking, PFSM is not hardware. It is a piece of code.
PMIC integrates a state machine which manages operational modes.
Depending on the current operational mode, some voltage domains
remain energized while others can be off.
PFSM driver can be used to trigger transitions between configured
states.

ESM description:
This device monitors the SoC error output signal at its nERR_MCU
input pin. On error detection, ESM driver toggles the PMIC nRSTOUT pin
to reset the SoC.

Regulators description:
4 BUCKs and 3 LDOs.
BUCK12 can be used in dual-phase mode.

Pinctrl description:
TPS65224 family has 6 GPIOs. Those GPIOs can also serve different
functions such as I2C or SPI interface or watchdog disable functions.
The driver provides both pinmuxing for the functions and GPIO capability.

[PATCH v2 01/14] mfd: tps6594: Add register definitions for TI TPS65224 PMIC

[Bhargav Raviprakash]

From: Nirmala Devi Mal Nadar <m.nirmaladevi@ltts.com>

Extend TPS6594 PMIC register and field definitions to support TPS65224
power management IC.

TPS65224 is software compatible to TPS6594 and can re-use many of the
same definitions, new definitions are added to support additional
controls available on TPS65224.

[PATCH v2 02/14] mfd: tps6594: use volatile_table instead of volatile_reg

[Bhargav Raviprakash]

In regmap_config use volatile_table instead of volatile_reg.
This change makes it easier to add support for TPS65224 PMIC.

[PATCH v2 03/14] mfd: tps6594: add regmap config in match data

[Bhargav Raviprakash]

Introduces a new struct tps6594_match_data. This struct
holds fields for chip id and regmap config. Using this
struct in of_device_id data field.
This helps in adding support for TPS65224 PMIC.

[PATCH v2 04/14] dt-bindings: mfd: ti,tps6594: Add TI TPS65224 PMIC

[Bhargav Raviprakash]

TPS65224 is a Power Management IC with 4 Buck regulators and 3 LDO
regulators, it includes additional features like GPIOs, watchdog, ESMs
(Error Signal Monitor), and PFSM (Pre-configurable Finite State Machine)
managing the state of the device.

In addition TPS65224 has support for 12-bit ADC and does not have RTC
unlike TPS6594.

[PATCH v2 09/14] misc: tps6594-esm: reversion check limited to TPS6594 family

[Bhargav Raviprakash]

The reversion check is only applicable on TPS6594 family of PMICs.
Conditionally add that check if the chip_id is one of the PMIC in
the TPS6594 family.

[PATCH v2 10/14] misc: tps6594-esm: use regmap_field

[Bhargav Raviprakash]

Use regmap_field and associated APIs to update the ESM_MODE_CFG and
ESM_START registers. This helps in adding support for TPS65224 PMIC.

[PATCH v2 12/14] regulator: tps6594-regulator: Add TI TPS65224 PMIC regulators

[Bhargav Raviprakash]

From: Nirmala Devi Mal Nadar <m.nirmaladevi@ltts.com>

Add support for TPS65224 regulators (bucks and LDOs) to TPS6594 driver
as they have significant functional overlap.
TPS65224 PMIC has 4 buck regulators and 3 LDOs. BUCK12 can operate in
dual phase.
The output voltages are configurable and are meant to supply power to
the main processor and other components.

[PATCH v2 13/14] pinctrl: pinctrl-tps6594: Add TPS65224 PMIC pinctrl and GPIO

[Bhargav Raviprakash]

From: Nirmala Devi Mal Nadar <m.nirmaladevi@ltts.com>

Add support for TPS65224 pinctrl and GPIOs to TPS6594 driver as they
have significant functional overlap.
TPS65224 PMIC has 6 GPIOS which can be configured as GPIO or other
dedicated device functions.

For tps6594, ESM_MCU interrupts were supposed to be cleared by the MCU FW. That's why we only had to 
deal with ESM_SOC interrupts in linux. For tps65224, I would recommend double-checking with TI where 
ESM_MCU interrupts should be handled (either in MCU FW or in the linux driver). For some reason this 
might be different than tps6594's case, but it does not look very consistent to me at first sight.

This might be a nitpick, but for the next version of the series, please make
commit message description for i2c VS spi drivers more homogeneous.
Same comment for MODULE_DESCRIPTION (you changed it for i2c: why not,
but then apply the same change to spi).
With these changes,

Instead of this if/else, a ternary operator might do the trick here:
regmap_clear_bits(pfsm->regmap, TPS6594_REG_FSM_NSLEEP_TRIGGERS,
                               pfsm->chip_id == TPS65224 ? TPS6594_BIT_NSLEEP1B : TPS6594_BIT_NSLEEP2B)

Following my comment related to ESM_MCU interrupts for 'tps6594.h':
Does it really make sense to add tps65224 ESM_MCU support in linux ?

For tps6594. TI requested a linux driver for ESM_SOC only (the "main" ESM).
No linux driver was requested for ESM_MCU.

Since tps65224 does not have ESM_SOC, I'm not sure that anything should
be done in linux for tps65224 ESM. Maybe you should discuss this point with
TI analog team (our TI contact for tps6594 was Chris Sterzik).

Regarding all the switch case, I think you should try and put all the
differences inside the `struct tps6594_pinctrl`. This way most of the
functions (if not all of them) could be writen without the switch case,
making them more readable and straight forward to understand.
You already have some switch case in the probe, why not fill the `struct
tps6594_pintcl` there and use these new fileds in the different
function.

It's not pretty today, imagine if in the future there is more supported
chip, it would be quite unreadable IMAO.

Other than that the changes looks fine to me. I will have to boot a
board with TPS6594 to check that whole series did not break anything.

Please add me to your Cc for the next round.

These should be REGULATOR_EVENT_REGULATION_OUT I think - they look like
they could be warning on either under or over voltage.

You prefixed your arrays with `tps65224` and that makes sense. However
you should also prefix the old ones with `tps6594` then.
This applies to the whole driver.

The comment is not adding anything, the name is clear and ARRAY_SIZE is

There is an indentation missing on the content of the `for` loop.

Also please don't abuse the ternery operator like this, write normal
conditionals or for a case like this where we may get more options in
future use switch statements.
