| Amlogic DDR bandwidth drvier |
| |
| This driver is used to measure DDR bandwidth, it can measure total |
| bandwidth of DDR, also can configure port in each channel and get |
| detailed bandwidth for each channel. |
| |
| Required properties for the root node: |
| - compatible: one of "amlogic,ddr-bandwidth-m8b" |
| "amlogic,ddr-bandwidth-gx" |
| "amlogic,ddr-bandwidth-gxl" |
| "amlogic,ddr-bandwidth-gxm" |
| "amlogic,ddr-bandwidth-gxlx" |
| "amlogic,ddr-bandwidth-axg" |
| "amlogic,ddr-bandwidth-g12a" |
| "amlogic,ddr-bandwidth-g12b" |
| "amlogic,ddr-bandwidth-txl" |
| "amlogic,ddr-bandwidth-txlx" |
| "amlogic,ddr-bandwidth-txhd" |
| "amlogic,ddr-bandwidth-tm2" |
| "amlogic,ddr-bandwidth-t7" |
| "amlogic,ddr-bandwidth-t3" |
| "amlogic,ddr-bandwidth-tl1" |
| "amlogic,ddr-bandwidth-a1" |
| "amlogic,ddr-bandwidth-c1" |
| "amlogic,ddr-bandwidth-t5" |
| "amlogic,ddr-bandwidth-t5d" |
| "amlogic,ddr-bandwidth-s4" |
| "amlogic,ddr-bandwidth-sc2" |
| "amlogic,ddr-bandwidth-p1" |
| "amlogic,ddr-bandwidth-t5w" |
| - reg: address and size of registers controlling bandwidth function |
| |
| Example: |
| |
| ddr_bandwidth { |
| compatible = "amlogic,ddr-bandwidth-g12a"; |
| status = "okay"; |
| reg = <0xff638000 0x100 |
| 0xff638c00 0x100>; |
| interrupts = <0 52 1>; |
| interrupt-names = "ddr_bandwidth"; |
| }; |
