Merge tag 'imx-clk-4.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into clk-next
Pull i.MX clk updates from Shawn Guo:
- Update clk-pllv3 driver to get it return correct frequency for
Ethernet PLL on i.MX7D.
- Correct ahb clock mux settings for i.MX7D per latest hardware
document.
