Subject: [PATCH 06/15] ALSA: hda/ca0132 - Add AE-5 pre-init and ca0113 functions
Date: Tue, 18 Sep 2018 14:33:34 -0400	[thread overview]
Message-ID: <1537295625-8082-7-git-send-email-conmanx360@gmail.com> (raw)
In-Reply-To: <1537295625-8082-1-git-send-email-conmanx360@gmail.com>

This patch adds AE-5 pre-init functions that happen before the main
ca0132_alt_init, and gives functions related to the ca0113 a ca0113
prefix instead of ca0132. It also adds functions to write to the 8051's
SFRs, and to write the special ca0113 commands for the AE-5.
