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.
