Subject: [PATCH V2 0/3] Anbernic RG-DS AW87391 Speaker Amps
Date: Wed, 28 Jan 2026 11:46:05 -0600 [thread overview]
Message-ID: <20260128174608.1498-1-macroalpha82@gmail.com> (raw)
From: Chris Morgan <macromorgan@hotmail.com>
Add support for the Anbernic RG-DS Speaker Amplifiers. The Anbernic
RG-DS uses two AW87391 ICs at 0x58 and 0x5B on i2c2. However, the
manufacturer did not provide a firmware file, only a sequence of
register writes to each device to enable and disable them.
Add support for this *specific* configuration in the AW87390 driver.
Since we are relying on a device specific sequence I am using a
device specific compatible string. This driver does not currently
support the aw87391 for any other device as I have none to test
with valid firmware. Attempts to create firmware with the AwinicSCPv4
have not been successful.
Changes since V1:
- Correct an uninitalized ret value error identified by kernel test
robot. [1]
https://lore.kernel.org/oe-kbuild-all/202601240757.gYdQGsXp-lkp@intel.com/
- Added devicetree binding for the Anbernic RG-DS. This is based on
the following commit that has since been accepted. [2]
