Subject: [PATCH 5/6] ASoC: intel: board: sof_rt5682: Update rt1015 pll input clk freq
Date: Fri, 17 Jul 2020 16:13:36 -0500 [thread overview]
Message-ID: <20200717211337.31956-6-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20200717211337.31956-1-pierre-louis.bossart@linux.intel.com>
From: Yong Zhi <yong.zhi@intel.com>
In commit d696a61413b4 ("ASoC: rt1015: Add condition to prevent SoC
providing bclk in ratio of 50 times of sample rate."), PLL input at 50fs
is no longer supported, the new recommended settings at 48Khz rate are:
PLL input SSP bclk
------------------------
64fs 3.073Mhz
100fs 4.8Mhz
(bclk update is reflected in topoplogy.)
