Hi Shawn & Stephen,

Would you help review this series? It's pending for a long time.

Regards
Dong Aisheng

> i.MX7ULP Clock functions are under joint control of the System Clock

> Core Mode Controller (CMC)1 blocks

> The clocking scheme provides clear separation between M4 domain and A7
> domain. Except for a few clock sources shared between two domains, such
> as the System Oscillator clock, the Slow IRC (SIRC), and and the Fast IRC clock
> (FIRCLK), clock sources and clock management are separated and contained
> within each domain.
>
> M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules.
> A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules.
>
> Note: this series only adds A7 clock domain support as M4 clock domain will
> be handled by M4 seperately.

> Change Log:
> v2->v3:
> * Patch 1 changed on: 1) split normal and gate ops 2) fix the possible racy
> Others no changes.
>
> v1->v2:
> * add enable/disable for the type of CLK_DIVIDER_ZERO_GATE dividers
> * use clk_hw apis to register clocks
> * use of_clk_add_hw_provider
> * split the clocks register process into two parts: early part for possible
> timers clocks registered by CLK_OF_DECLARE_DRIVER and the later part for
> the left normal peripheral clocks registered by a platform driver.
