Rob Herring, Krzysztof Kozlowski, Conor Dooley, Liam Girdwood, Mark Brown, Arnaud Pouliquen, Linus Torvalds
Update the examples, as otherwise driver errors with an incorrect mclk ratio at runtime. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Cc: arnaud.pouliquen at st.com --- Documentation/devicetree/bindings/sound/st,sti-asoc-card.txt | 8 ++++++++ 1 file changed, 8 insertions(+)
