> Subject: [PATCH V2 00/10] clk: add imx7ulp clk support
>
> This patch series intends to add imx7ulp clk support.
>
> i.MX7ULP Clock functions are under joint control of the System Clock
> Generation (SCG) modules, Peripheral Clock Control (PCC) modules, and 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:
> 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.
