| ST,stm32mp1 DDR3/LPDDR2/LPDDR3 Controller (DDRCTRL and DDRPHYC) |
| |
| -------------------- |
| Required properties: |
| -------------------- |
| - compatible : Should be "st,stm32mp1-ddr" |
| - reg : controleur (DDRCTRL) and phy (DDRPHYC) base address |
| - clocks : controller clocks handle |
| - clock-names : associated controller clock names |
| the "ddrphyc" clock is used to check the DDR frequency |
| at phy level according the expected value in "mem-speed" field |
| |
| the next attributes are DDR parameters, they are generated by DDR tools |
| included in STM32 Cube tool |
| |
| info attributes: |
| ---------------- |
| - st,mem-name : name for DDR configuration, simple string for information |
| - st,mem-speed : DDR expected speed for the setting in MHz |
| - st,mem-size : DDR mem size in byte |
| |
| |
