Subject: [PATCH v2 0/2] ASoC: es8316: Add regulator support
Date: Wed, 12 Aug 2026 17:35:42 +0800 [thread overview]
Message-ID: <20260812-es8316-regulator-next-20260722-v2-0-e7078bc9bc9c@thundersoft.com> (raw)
Add regulator support for the four ES8316 power domains so board
descriptions can model and control the codec supplies.
The binding patch documents AVDD, CPVDD, DVDD and PVDD as optional
supplies for ES8316, preserving compatibility with existing device-tree
descriptions. The driver patch enables the supplies before initializing
the regmap and keeps them enabled for the lifetime of the I2C device.
The missing supply model was identified while reviewing the RubikPi 3
audio support:

Changes in v2:
- Restrict the supply properties to the ES8316 compatible.
- Enable the regulators before regmap initialization and keep them enabled
for the lifetime of the I2C device.
- Link to v1: https://lore.kernel.org/r/20260723-es8316-regulator-next-20260722-v1-0-721f757879a0@thundersoft.com
