* ARM i.MX31 clk: add pll_ref_clk and MCU PLL bypass selectAlexander Kurz2017-01-261-5/+23
| | | | | | | | | | | The three MX31 PLL may be clocked from either CKIH or a frequency-multiplied derivate of CKIL generated by the Frequency Pre Multiplier FPM. Add the pll_ref_clk selection infrastructure and support for MCU PLL bypass to support clock switching and boards not clocked CKIH.

* i.MX: Move clk code from 'mach-imx' to 'drivers'Andrey Smirnov2017-01-111-0/+146
Move clk code from 'mach-imx' to 'drivers' to keep the code tree structure closer to that of analogous one from Linux kernel and, arguably although subjective, to keep 'mach-imx' less cluttered.
