Subject: [PATCH v2 0/1] clk: sunxi-ng: v3s: use sigma-delta modulation for audio-pll

Hi,

this patch extends the v3s audio-pll declaration to use sdm for supporting
24.576MHz and 22.5792MHz clock rates, required by the i2s peripheral driver.

This is v2 of the patch. The previous version used a flexible postdivider only.
However, that setup was unable to provide the 22.5792MHz clock rate.

Cheers,
Tobias

Changelog:
 v2:
  - use sdm instead of postdivider for audio-pll
  - change patch subject to reflect use of sdm
