Subject: doc: update documentation to obsolete function support of ALSA HwDep
 cdev

All of HinawaSnd* object classes and structures are supported by libhitaki
instead. Let's obsolete current implementations.

 Title: Overview
 
-This library gives some objects for abstraction to operate system resources in two Linux
-subsystems; FireWire subsystem and Sound subsystem.
+This library gives some objects for abstraction to operate system resources in Linux FireWire
+subsystem. This library mainly supports operations for asynchronous communication to nodes on
+IEEE 1394 bus.
 
-This library mainly supports operations for asynchronous communication to nodes on IEEE 1394 bus.
-Additionally, this library supports some model-specific operations for Audio and Music units on
-IEEE 1394 bus, supported by drivers in ALSA firewire stack.
+This library originally supported some model-specific operations for Audio and Music units on
+IEEE 1394 bus, assisted by drivers in ALSA firewire stack as well, however the support has already
+been migrated to [libhitaki](https://github.com/alsa-project/libhitaki) library nowadays and
+obsoleted since v2.5 release.
 
 ![Overview of libhinawa](overview.png)
 
-This library expects userspace applications to use GMainContext to run event dispatcher with
-GSource from HinawaFwNode and HinawaSndUnit. Additionally this library launches a thread for event
-notifier which emits GObject signal and execute any handler on this thread so that the handler can
-wait for events from the dispatcher.
+This library expects userspace applications to use [struct@GLib.MainContext] to run event
+dispatcher with [struct@GLib.Source] from [class@FwNode].
 
 libhinawa supports gobject introspection, thus this library is available with gobject introspection
 bindings of each language such as Python, Ruby and so on. When using this mechanism, please refer
