Introduction
For me, it was the requirement to add a LCD panel to my Raspberry Pi. This was a Sain Smart LCD.
After some searching I decided to use fbtft as the driver for accessing this LCD. For this solution, I had to build a kernel module.
In this post, I describe the single steps to build a kernel and/or integrate a new module into the kernel.
For the integration of the Sain Smart module see me post Add Sain Smart LCD to Raspberry Pi
