Subject: [PATCH 1/5] ASoC: mediatek: make agent_disable, msb & hd fields optional
Date: Thu,  2 May 2019 14:10:37 +0200	[thread overview]
Message-ID: <20190502121041.8045-2-fparent@baylibre.com> (raw)
In-Reply-To: <20190502121041.8045-1-fparent@baylibre.com>

Not every SoC have the following registers: agent_disable_reg,
msg_reg, and hd_reg. Make them optional in order to allow more
SoC to use the common DAI FE code.
