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.

2023-05-21ddr: imx93: update the ddr init to support mult setpointsJacky Bai
Update the DDR init flow for multi-setpoint support on i.MX93. A new fsp_cfg struct need to be added in the timing file to store the diff part of the DDRC and DRAM MR register for each setpoint.

2023-05-21ddr: imx9: Add workaround for DDRPHY rank-to-rank errataYe Li
According to DDRPHY errata, the Rank-to-Rank Spacing and tphy_rdcsgap specification does not include the Critical Delay Difference (CDD) to properly define the required rank-to-rank read command spacing after executing PHY training firmware. Following the errata workaround, at the end of data training, we get all CDD values through the MessageBlock, then re-configure the DDRC timing of WWT/WRT/RRT/RWT with comparing MAX CDD values.

2022-07-26ddr: imx: Add i.MX9 DDR controller driverYe Li
Since i.MX9 uses same DDR PHY with i.MX8M, split the DDRPHY to a common directory under imx, then use dedicated ddr controller driver for each iMX9 and iMX8M. The DDRPHY registers are space compressed, so it needs conversion to access the DDRPHY address. Introduce a common PHY address remap function for both iMX8M and iMX9 for all PHY registers accessing.
