Sorry, but imho it should go to net-next, and you might have overlook
it but there have been some concerns.

For sure it should not go to net tree as you are enabling a new feature
and not fixing anything which is broken. EEE on MT7988 works fine as
of now (see my reply), EEE on MT7531 was supposedly intentionally
disabled for reasons we should ask MTK people about.

OK, here I get your point. Appreciate your patient explanation so that

I tried to guess your comment "Those routines are essentially position

you have explained it completely. I have total understand it.

Bindings are before users.

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.
There is no file extension in prefixes.

No, use existing, generic properties. Open other bindings for this.

Also, none of these were tested. I am not going to review such untested
code.

It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.

Best regards,
Krzysztof

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.

* [PATCH v4 09/11] regulator: tps6594-regulator: Add TI TPS65224 PMIC regulators
From: Bhargav Raviprakash @ 2024-03-20 10:25 UTC (permalink / raw)

In-Reply-To: <20240320102559.464981-1-bhargav.r@ltts.com>

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 v4 07/11] mfd: tps6594-core: Add TI TPS65224 PMIC core
From: Bhargav Raviprakash @ 2024-03-20 10:25 UTC (permalink / raw)
  To: linux-kernel
  Cc: m.nirmaladevi, lee, robh+dt, krzysztof.kozlowski+dt, conor+dt,

In-Reply-To: <20240320102559.464981-1-bhargav.r@ltts.com>

Add functionality of the TPS65224 PMIC to the TPS6594 core driver. This
includes adding IRQ resource, MFD cells, and device initialization for
TPS65224.

In-Reply-To: <20240320102559.464981-1-bhargav.r@ltts.com>

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.

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

* [PATCH v4 01/11] mfd: tps6594: Add register definitions for TI TPS65224 PMIC

In-Reply-To: <20240320102559.464981-1-bhargav.r@ltts.com>

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 v4 00/11]  Add support for TI TPS65224 PMIC
From: Bhargav Raviprakash @ 2024-03-20 10:25 UTC (permalink / raw)
  To: linux-kernel
  Cc: m.nirmaladevi, lee, robh+dt, krzysztof.kozlowski+dt, conor+dt,

	linus.walleij, linux-gpio, linux-arm-kernel, nm, vigneshr, kristo,
	eblanc, 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	
- 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.

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.

This series was tested on linux-next tag: next-20240118

Test logs can be found here:
https://gist.github.com/LeonardMH/58ec135921fb1062ffd4a8b384831eb0

Changelog v3 -> v4:
- Removed ESM MCU interrupts from tps6594.h
- Fixing indentation and minor refactoring 
  in regulator
- Regarding switch cases in pinctrl, added fields in pinctrl struct and
  using those to differentiate between chips.

Sorry, I don't see a point in making that a separate patch: the
clock-indices in the DT binding header are only used by the DTS.
R-Mobile APE6 still uses the legacy CPG/MSTP DT bindings. The DTS
for newer SoCs just hardcodes the indices (as part of the full module
clock number, straight from the hardware documentation).
