Subject: RE: [PATCH V4 0/9] clk: add imx7ulp clk support

Hi Stephen,

Do you have a chance to look at it?
This patch series has been pending for quite a long time without much comments.

Regards
Dong Aisheng

> 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:
> v3->v4:
>  * rebased to latest kernel
>  * make scg and pcc separate nodes according to Rob's suggestion
> 
> 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.
