The i.MX SoC updates for 4.2:
- Add new SoC i.MX7D support, which integrates two Cortex-A7 and one
Cortex-M4 cores.
- Support suspend from IRAM on i.MX53, so that DDR pins can be set to
high impedance for more power saving during suspend.
- Move i.MX clock drivers from arch/arm/mach-imx to drivers/clk/imx.
- Move i.MX GPT timer driver from arch/arm/mach-imx into
drivers/clocksource.
- A couple of clock driver update for VF610 and i.MX6Q.
- A few random code correction and improvement.
