Subject: [PATCH 1/3] firmware: imx: Introduce imx_dsp_setup_channels
Date: Wed,  8 Jul 2020 10:35:54 +0300	[thread overview]
Message-ID: <20200708073556.19188-2-daniel.baluta@oss.nxp.com> (raw)
In-Reply-To: <20200708073556.19188-1-daniel.baluta@oss.nxp.com>

From: Daniel Baluta <daniel.baluta@nxp.com>

Create a separate function that sets up DSP mailbox channels
so that imx_dsp_probe function will be easier to read.
