d678a59d2d Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

01aa4cd8ba imx8ulp: ddr: Fix DDR frequency request issue
After acking the requested frequency, should wait the ack bit clear
by DDR controller and check the DFS interrupt for next request polling.
Otherwise, the next polling of request bit will get previous value
that DDR controller have not cleared it, so a wrong request frequency
is used.
