Subject: [PATCH] ASoC: wm8804: Cleanup of post_table


Signed-off-by: Daniel 
Matuschek <inof@...zy-audio.com>

  Existing post_table has duplicate settings for some PLL settings.
  Only the first setting was used with mclk_div=1
  With the updated post_table, the driver
  uses mclk_div=0 whenever it is possible. This allows the WM8804
  to work at 256xfs internal clock and only use 128xfs
  internal clock for high sample rates where 256xfs is not
  supported anymore.
