Sorry for the late reply, and the rude action before. I' m not quite familiar with the email rules, I will pay attention to it.</div>

What I'm trying to do is to become a kernel developer, especially a driver developer. Maybe this is a more general object and lacks of clear steps. So I want to learn about the work flow ofkernel development to decompose the object.</div>

And, I think, maybe the first step is to catch up with a branch of kernel source, for which I setup a raspi to track the kernel source daily with the help of crontab, and compile the kernel when there is a new commit and send an email to get a notification.
Next, I should develop on the specific branch, and learn how to submit a patch to kernel.</div>

But now, I'm confused that there so many branches in linux kernel source and other linux distribution source such as raspberrypi/linux.git, and I only know about how to submit a patch to kernel from kernel documents or kernelnewbies or other websites. Can I
just work on a specific platform and submit a patch to kernel?</div>

I currently work on i.mx6 platform and have a raspi4b for learning. Based on the linux SDK from board supplier, l developed some camera drivers. The SDK contains a dirty 4.1.15 kernel source, a uboot, anda prebuild rootfs archive. and the SDK is not controlled
by a git, it's just an archive.</div>

<div dir="auto" style="font-family:-apple-system, HelveticaNeue;background-color:white">
Supposed now, I know how to submit a patch to which branch, is therep any tests need to be run before I submit? or is there a requirement for writing a test program to test my driver first?</div>

It all depends on what you want to do as to what tree/branch to work off<br>
of and to track.<br>
<br>
So, what exactly do you want to do?<br>
<br>
thanks,<br>
