Really no. Old products would still be using Linux-3.18 kernel without kernel upgrade. For new product, most of SoC vendors will use Linux-4.x including us.
Actually, we are preparing for kernel upgrade for some devices even some old devices (to Linux-4.14-LTS) and almost done.

We also want to move to latest kernel version. However, there is a case that we cannot upgrade the kernel.
In case that SoC vendor never share firmwares and relevant data sheets, we cannot upgrade the kernel. However, we have to resolve the security issues for users of this device.
