Subject: [PATCH] ASoC: wm8741: Fix setting BCLK and LRCLK polarity
After checking the code and the datasheet, it seems like we are handling
the clock inversion (SND_SOC_DAIFMT_NB_IF and SND_SOC_DAIFMT_IB_IF) not
correctly.
>From the datasheet (Table 58):
R5 Format Control, BITS[5:4], [BCP:LRP]:
(0) 00 = normal BCLK, normal LRCLK
(1) 01 = normal BCLK, inverted LRCLK <-- Fix this
(2) 10 = inverted BCLK, normal LRCLK
(3) 11 = inverted BCLK, inverted LRCLK <-- Fix this
