Ping...
Gently ping again...

Hi Stephen,

This has been more there without comments for more than one month.

Would you help review when you're available later?

Regards

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.
