| 2 | |
| 3 | -------------------- |
| 4 | Required properties: |
| 5 | -------------------- |
| 6 | - compatible : Should be "st,stm32mp1-ddr" |
| 7 | - reg : controleur (DDRCTRL) and phy (DDRPHYC) base address |
| 8 | - clocks : controller clocks handle |
| 9 | - clock-names : associated controller clock names |
| 10 | the "ddrphyc" clock is used to check the DDR frequency |
| 11 | at phy level according the expected value in "mem-speed" field |
| 12 | |
| 13 | the next attributes are DDR parameters, they are generated by DDR tools |
| 14 | included in STM32 Cube tool |
| 15 | |
| 16 | info attributes: |
| 17 | ---------------- |
| 18 | - st,mem-name : name for DDR configuration, simple string for information |
| 19 | - st,mem-speed : DDR expected speed for the setting in MHz |
| 20 | - st,mem-size : DDR mem size in byte |
| 21 | |
| 22 | |
| 23 | controlleur attributes: |
