-Subject: [PATCH] ASoC: wm8804: MCLK configuration options, 32-bit
-
-WM8804 can run with PLL frequencies of 256xfs and 128xfs for most sample
-rates. At 192kHz only 128xfs is supported. The existing driver selects
-128xfs automatically for some lower samples rates. By using an
-additional mclk_div divider, it is now possible to control the
-behaviour. This allows using 256xfs PLL frequency on all sample rates up
-to 96kHz. It should allow lower jitter and better signal quality. The
-behavior has to be controlled by the sound card driver, because some
-sample frequency share the same setting. e.g. 192kHz and 96kHz use
-24.576MHz master clock. The only difference is the MCLK divider.
-
-This also added support for 32bit data.

-Some Raspberry Pis have limited RAM and most users won't use the
