Hi,

I did not use a cover letter in v1, so here is a summary instead.

I discovered a problem when trying to set the rate of the audio PLL
(pll4_post_div) on an i.MX6Q. The rate I wanted to set was 196.608 MHz, but
the actual rate I got was 192.000570 MHz. This patch series fixes this
issue and also improves the precision of the audio/video PLL.

There are no code changes in v2, only clarifications in the commit
messages.

Changes since v1:
- Use correct subsystem name in commit summary.
- Use 'Fixes:' tag to indicate bug fix.
- Revise argument for choosing the denominator register value after
  comments from Lothar Waßmann.

  clk: imx: improve precision of AV PLL to 1 Hz
