可以使用clk_register_divider()函数注册一个时钟分频器,在使用时可以通过clk_set_rate()函数设置该时钟的频率。 Fractional-N PLL Clock(分数-N锁相环时钟):利用锁相环(PLL)技术生成可变频率的时钟信号。可以使用clk_register_pll()函数注册一个分数-N锁相环时钟。 Fixed Factor Clock(固定倍频时钟):表示一个时...

由于parent clock的频率可以改变,因而fix factor clock也可该改变频率,因此也会提供.recalc_rate/.set_rate/.round_rate等回调。以第一行的clk为例,这里的"sys_pll1_50m"就是我们想要的fixed factor clock。“sys_pll1_50m"的clk的父时钟节点为"sys_pll2_out”(1000MHz),倍频系数为1,分频系数为20。 (3)...
