-Subject: [PATCH] ASoC: sun4i-i2s: Don't use the oversample to calculate BCLK
-
-The BCLK divider should be calculated using the parameters that actually
-make the BCLK rate: the number of channels, the sampling rate and the
-sample width.
-
-We've been using the oversample_rate previously because in the former SoCs,
-the BCLK's parent is MCLK, which in turn is being used to generate the
-oversample rate, so we end up with something like this:
-
-oversample = mclk_rate / sampling_rate
-bclk_div = oversample / word_size / channels
-
-So, bclk_div = mclk_rate / sampling_rate / word_size / channels.
-
-And this is actually better, since the oversampling ratio only plays a role
-because the MCLK is its parent, not because of what BCLK is supposed to be.
-
-Furthermore, that assumption of MCLK being the parent has been broken on
-newer SoCs, so let's use the proper formula, and have the parent rate as an
-argument.
-
-Fixes: 7d2993811a1e ("ASoC: sun4i-i2s: Add support for H3")
-Fixes: 21faaea1343f ("ASoC: sun4i-i2s: Add support for A83T")
-Fixes: 66ecce332538 ("ASoC: sun4i-i2s: Add compatibility with A64 codec I2S")
