Convert the TWL4030 audio module bindings from txt to YAML format and
move them to the sound subsystem bindings directory. This patch also
refines the schema by adding an enum constraint for ti,enable-vibra and
updates the example to remove irrelevant I2C clock-frequency property.
Changes in v2:
- Moved binding from mfd to sound directory.
- Added enum: [0, 1] to ti,enable-vibra for stricter validation.
- Removed clock-frequency from the example as it’s not relevant to the binding.
- Simplified example by removing unnecessary I2C node properties.

Convert the legacy TXT binding for the TWL6040 MFD to the modern YAML
DT schema format. This adds formal validation and improves documentation
for the TWL6040/TWL6041 audio codec, which provides audio, vibra, and GPO
functionality on OMAP4+ platforms.
Changes in v2:
- Renamed twl6040,audpwron-gpio to ti,audpwron-gpio for consistency
with TI naming, this fixes the dt_binding_check vendor name error.
- Minor description clarifications for improved readability.

This is unrelated to the PMIC stuff and can be handled separely, I would
propose to send it separately and not part of this series in further
submissions.

Convert the legacy TXT binding for the TWL4030 keypad module
to the modern YAML DT schema format. This adds formal validation
and improves documentation by inheriting from the matrix-keymap schema.
Changes in v2:
Simplified the description field by removing redundant '|'
as it does not affect formatting in this context.

I wonder if "linux,keymap" should not be made required as well...

Convert the legacy TXT binding for the TWL4030 power module
to the modern YAML DT schema format. This adds formal validation
and improves documentation.
Changes in v2:
Simplified the description field by removing redundant '|' as it
does not affect formatting in this context.

-Texas Instruments TWL family (twl4030) reset and power management module
-
-The power management module inside the TWL family provides several facilities
-to control the power resources, including power scripts. For now, the
-binding only supports the complete shutdown of the system after poweroff.
-
-Required properties:
-- compatible : must be one of the following
- "ti,twl4030-power"
- "ti,twl4030-power-reset"
- "ti,twl4030-power-idle"
- "ti,twl4030-power-idle-osc-off"
-
-The use of ti,twl4030-power-reset is recommended at least on
-3530 that needs a special configuration for warm reset to work.
-
-When using ti,twl4030-power-idle, the TI recommended configuration
-for idle modes is loaded to the tlw4030 PMIC.
-
-When using ti,twl4030-power-idle-osc-off, the TI recommended
-configuration is used with the external oscillator being shut
-down during off-idle. Note that this does not work on all boards
-depending on how the external oscillator is wired.
-
-Optional properties:
-
-- ti,system-power-controller: This indicates that TWL4030 is the
- power supply master of the system. With this flag, the chip will
- initiate an ACTIVE-to-OFF or SLEEP-to-OFF transition when the
- system poweroffs.

yes, this is ugly use of compatible, but not easy being patched away.

this too is deprecated, we already have the system-power-controller
node in the parent.

I think we can even totally drop this and maybe add this whole stuff to
ti,twl.yaml, no extra file.

Convert the legacy TXT binding for the OMAP TWL4030 sound card
to the modern YAML DT schema format. This adds formal validation
and improves documentation.
Changes in v2:
- Fixed comment formatting (added spaces for better alignment).
- Updated commit subject to align with subsystem style.
- Retained Acked-by from v1 as changes are cosmetic.

Hi Mark,
Thanks for the quick feedback. I've corrected the subject line and
changelog placements.
I will wait until early next week for any other potential reviews
before sending v3 to bundle any changes together.

Convert the legacy TXT binding for the TWL4030/6030 USB module
to the modern YAML DT schema format. This adds formal validation
and improves documentation using a conditional schema.
Changes in v2:
- Added '#phy-cells' property to support PHY framework integration.

jihed.chaibi.dev
Update the TI TWL family Device Tree binding to include additional
subnodes for TWL4030, TWL6030, and TWL6032 devices.
This patch enhances the schema by adding support for audio, GPIO, power,
keypad, PWM, PWM LED, and USB subnodes, referencing their respective YAML
schemas where applicable. These additions improve the schema's
completeness, enabling better validation and documentation of the
TWL multi-function device's capabilities.
The changes ensure proper handling of TWL4030-specific features (audio,
keypad, PWM, PWM LED, USB, GPIO, and power) and TWL6030/TWL6032-specific
features (PWM, PWM LED, and USB), with appropriate schema references to
prevent unevaluated properties.
