NettetWith the not yet included extension for the new PWM block (channel->clock directly coming from get_clk(external_clk)) I didn't notice any problem. My system uses PWM for the CPU voltage regulator and for the SDIO 32kHz clock. Note: The clock gate in the old PWM block is permanently disabled.
NettetIntroduction and interface split ¶. The common clk framework is an interface to control the clock nodes available on various devices today. This may come in the form of clock gating, rate adjustment, muxing or other operations. This framework is enabled with the CONFIG_COMMON_CLK option. The interface itself is divided into two halves, each ... Nettet31. mar. 2024 · 这决定了clock provider的DTS怎么写。 通常有两种方式: 方式1,将系统所有的clock,抽象为一个虚拟的设备,用一个DTS node表示。 这个虚拟的设备称作clock controller,参考如下例子: 1: /* arch/arm/boot/dts/exynos4210.dtsi */ 2: clock: clock-controller@0x10030000 { 3: compatible = "samsung,exynos4210-clock"; 4: reg = …
Nettet18. okt. 2016 · common clock framework是用来管理系统clock资源的子系统,根据职能,可分为三个部分: 1)向其它driver提供操作clocks的通用API。 2)实现clock控制的通用逻辑,这部分和硬件无关。 3)将和硬件相关的clock控制逻辑封装成操作函数集,交由底层的platform开发者实现,由通用逻辑调用。 因此,蜗蜗会将clock framework的分析 … Nettet19. jun. 2024 · 在“ Linux common clock framework (2)_clock provider ”中已經講過,clock provider需要將系統的clock以tree的形式組織起來,分門別類,並在系統初始化時,通過provider的初始化接口,或者clock framework core的DTS接口,將所有的clock註冊到kernel。 clock的註冊,統一由clk_regitser接口實現,但基於該接口,kernel也提供 …
