Subject: [patch 2/4] staging: serial: add spk_io_ops struct to spk_synth
Date: Tue, 14 Mar 2017 13:41:53 +0000	[thread overview]
Message-ID: <20170314134519.474280829@gmail.com> (raw)
In-Reply-To: 20170314134151.603195427@gmail.com

[-- Attachment #1: 02_add_spk_io_ops --]
[-- Type: text/plain, Size: 14836 bytes --]

This patch adds spk_io_ops struct which contain those methods whose job is to
communicate with synth device. Currently, all comms with external synth
device use raw serial i/o. The idea is to group all methods which do the
actual communication with external device into this new struct. Then migrating
a serial-based synth over to an alternative to raw serial i/o will mean
swapping serial spk_io_ops instance with the io_ops instance of the new
method, making the migration simpler.

At the moment, this struct only contains one method, synth_out but more will
be added in future when migrating synths which require input functionality.
Also at the moment, synth_out method has one implementation which uses
serial i/o. Plan is to add an alternative.
