The support of a predefined DDR PHY tuning result is removed for STM32MP1 driver because it is not needed at the supported frequency when built-in calibration is executed. The calibration parameters were provided in the device tree by the optional node "st,phy-cal", activated in ddr helper file by the compilation flag DDR_PHY_CAL_SKIP and filled with values generated by the CubeMX DDR utilities. This patch - updates the binding file to remove "st,phy-cal" support - updates the device trees and remove the associated defines - simplifies the STM32MP1 DDR driver and remove the support of the optional parameter "st,phy-cal" After this patch, the built-in calibration is always executed and the calibration registers are moved in the phy dynamic part; that allows manual tests.
