[PATCH 0/3] soc: mediatek: pwrap: MT6589 + MT6320 support

[Akari Tsuyukusa]

This patch series adds support for MediaTek MT6589 PWRAP and MT6320
PMIC which are used together.
It also adds minimum compatibility string for MT6320.

Tested on Lenovo YOGA Tablet 10 Wi-Fi model.

[PATCH 1/3] dt-bindings: soc: mediatek: pwrap: Add compatible for MT6589 SoC

[Akari Tsuyukusa]

Add compatible string for MediaTek MT6589 PWRAP.
Also update the description since MT6589 has pwrap bridge.

[PATCH 3/3] soc: mediatek: pwrap: add MT6589 PWARP and MT6320 PMIC support

[Akari Tsuyukusa]

Add support for MediaTek MT6589 PWRAP and MT6320 PMIC which are used
together.

Since the PWRAP Bridge hardware on MT6589 is identical to the one on
MT8135, refactor the existing register definitions:
- Rename the MT8135-specific "PWRAP_MT8135_BRIDGE_" prefix to a generic
  "PWRAP_BRIDGE_" prefix to reflect that they are shared across SoCs.
- Add the full set of PWRAP Bridge registers to match the hardware
  specification, rather than defining only a subset of them.

dt-bindings: mfd: mediatek: mt6397: add MT6320 compatible string

This commit adds the mediatek,mt6320 compatible string to the MT6397 PMIC
device tree binding.

> dt-bindings: mfd: mediatek: mt6397: add MT6320 compatible string

[Severity: Low]
This isn't a bug, but the MFD subsystem guidelines request that the
description following the subsystem prefix be capitalized. Should "add" be
changed to "Add"?

[Severity: Low]
Will adding this top-level compatible string without updating the child
regulator nodes cause schema validation to fail for a complete MT6320 node?

Looking at the properties:regulators section in this file, the compatible
enum only allows mediatek,mt6323-regulator and mediatek,mt6328-regulator.
Does the MT6320 require a corresponding compatible string added to the
regulators sub-node, or a fallback to one of the existing variants?

soc: mediatek: pwrap: add MT6589 PWARP and MT6320 PMIC support

This commit adds support for the MediaTek MT6589 PWRAP and MT6320 PMIC.
It also refactors the existing MT8135 bridge register definitions to use
a generic prefix.

[Severity: Medium]
Does using PWRAP_DEW_DIO_EN here instead of PWRAP_SLV_CAP_DUALIO accidentally
disable Dual I/O mode?

PWRAP_DEW_DIO_EN is an enumeration value for a register index that evaluates
to 1 (since PWRAP_DEW_BASE is 0). PWRAP_SLV_CAP_SPI is BIT(0), which also
equals 1. Bitwise ORing them together results in a bitmask that completely
omits the intended Dual I/O capability, as PWRAP_SLV_CAP_DUALIO is BIT(1).

This causes HAS_CAP(wrp->slave->caps, PWRAP_SLV_CAP_DUALIO) to evaluate to
false during pwrap_init(), skipping pwrap_init_dual_io() and leaving the
PMIC wrapper in single I/O SPI mode.
