From 3b94253bc9c950d2038a2db4f9c804b50f82001a Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 21 Jan 2008 08:51:19 +0100 Subject: [ALSA] oxygen: reduce SPI clock frequency for AK4396/WM8785 According to the datasheets, the SPI clock cycle must be at least 200 ns for the AK4396 and the WM8785, so we cannot use the default 160 ns.
