Subject: [PATCH 1/2] ALSA: pcm: Add support for 705.6KHz and 768KHz sample rate
Date: Tue, 27 Apr 2021 18:34:22 +0800	[thread overview]
Message-ID: <1619519663-10406-1-git-send-email-shengjiu.wang@nxp.com> (raw)

Some high resolution codecs support 705.6KHz and 768KHz rates.
So extend supported sample rate to 768kHz in pcm.h.
