This patch causes QCS6490 RB3Gen2 to hit a bus timeout and crash during
boot, unless the associated DeviceTree change (adding clocks) is
present.
The two patches are reaching linux-next, and hence mainline, through
different code paths we now have periods where rb3gen2 is not bootable.
But more importantly, devices with current .dtbs installed can not boot
the new kernel.
It is not acceptable to introduce non-backwards compatible changes in
drivers (unless there's extraordinary reasons to do so).
Regards,
Bjorn
