On an NXP i.MX6 Solo processor we are running an application which makes
use of real-time threads (SCHED_RR). In combination with a DA9063 we
experienced (rare) random shut-downs and reboots. We found that the
issue was caused by a combination of the (default) DA9063 SMBus mode
and non-atomic I2C
mainline kernel. Though, we tested a (very similar)
patch on our (close to mainline) Linux 4.14 and 5.4 vendor kernels.
Cheers,
Mark

. This leads to a dark
screen until a KMS application (or fbcon) sets the screen mode.
This patch fixes the issue by moving the setup of generic fbdev before
initializing and enabling output polling.
