2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
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 c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

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.
