Subject: ASoC: wm8978: pll incorrectly configured when codec is master
From: Eric Millbrandt <[email protected]>
commit 55c6f4cb6ef49afbb86222c6a3ff85329199c729 upstream.
When MCLK is supplied externally and BCLK and LRC are configured as outputs
(codec is master), the PLL values are only calculated correctly on the first
transmission. On subsequent transmissions, at differenct sample rates, the
wrong PLL values are used. Test for f_opclk instead of f_pllout to determine
if the PLL values are needed.
