根据device tree代码分析,我们知道,在系统初始化的时候,dts描述的device node会形成一个树状结构,在machine初始化的过程中,会scan device node的树状结构,将真正的硬件device node变成一个个的设备模型中的device结构(比如struct platform_device)并加入到系统中。我们看看具体2416描述pin controller的dts code,如下: pin...

consumers, I'd be glad to have one device per bank (and that's actually in my plans for future), but this requires an update of all GPIO clients in DTS files, I deliberately separate this task from the GPIO controller driver update task. * only P2 bank has controls to set output val...
