[PATCH v3 0/2] clk: imx: fix AV PLL rate setting

[emil@limesaudio.com (Emil Lundmark)]

Hi,

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 PLLs.

Changes since v2:
- Cast result of 'parent_rate * mfn / mfd' to unsigned long instead of u32.
- Clarify how this issue was discovered in the commit message.
- Rebased on Linux 4.8.

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 Wa?mann.

v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2016-October/460350.html

  clk: imx: fix integer overflow in AV PLL round rate
  clk: imx: improve precision of AV PLL to 1 Hz
