Hi list,
since v4.16-rc1 my board imx53-cx9020 shows multiple WARNINGs like this:

At first I suspected the new rtc-mxc_v2 driver, but even with CONFIG_RTC_DRV_MXC_V2 not set
I get the same WARNINGs.
Reverting commit 59dc3d8c867370b4860c9df3eb5483da46823a4b made them disappear (w/o rtc driver).
I have no idea what's happening, as CX9020 is using uart2. Do you have an idea?
Thanks and regards,
Patrick
