Subject: [PATCH v2 3/5] ALSA: hda/ca0132 - Add 8051 exram helper functions.
Date: Thu, 10 Dec 2020 11:06:55 -0500 [thread overview]
Message-ID: <20201210160658.461739-4-conmanx360@gmail.com> (raw)
In-Reply-To: <20201210160658.461739-1-conmanx360@gmail.com>
Add functions for both reading and writing to the 8051's exram. Also,
add a little bit of documentation on how the addresses are segmented.
