Hi,
I understand that the .dtsi is from SoC chip level and .dts is from board level respectively.
I have a question when comes to this ls1021a.dtsi
(1)Why there is a gpio3 there at the node section, what does that use for?
(2)And why sysclk doesn't have a cell for address register because sysclk isn't a memory I/O device?
(3) Also the status section
can this be inside of the .dtsi as well, I thought this can only be inside of the .dts file only to disable or enable the node.
1. It is used to define GPIO module.
2. Yes, sysclk isn't a memory I/O device.
3. Status can be used inside of the .dtsi.
