This is a resend patch series. See the original one from here: [PATCH V3 00/10] clk: add imx7ulp clk support https://lkml.org/lkml/2018/1/19/351 No function changes but remove the last one which is used for the test. Rebased against clk-next branch.
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: 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.
