Subject: [PATCH 09/18] ALSA: hda: cs35l56: Initialize all ASP1 registers
Date: Mon, 29 Jan 2024 16:27:28 +0000 [thread overview]
Message-ID: <20240129162737.497-10-rf@opensource.cirrus.com> (raw)
In-Reply-To: <20240129162737.497-1-rf@opensource.cirrus.com>
Add ASP1_FRAME_CONTROL1, ASP1_FRAME_CONTROL5 and the ASP1_TX?_INPUT
registers to the sequence used to initialize the ASP configuration.
Write this sequence to the cache and directly to the registers to
ensure that they match.
A system-specific firmware can patch these registers to values that are
not the silicon default, so that the CS35L56 boots already in the
configuration used by Windows or by "driverless" Windows setups such
as factory tuning.
These may not match how Linux is configuring the HDA codec. And anyway
on Linux the ALSA controls are used to configure routing options.
