| Honghui Zhang | 7e42626 | 2016-06-08 17:50:57 +0800 | [diff] [blame] | 6 | - compatible : must be one of : |
| 7 | "mediatek,mt8173-smi-larb" |
| 8 | "mediatek,mt2701-smi-larb" |
| Yong Wu | fb6e2ce | 2016-02-23 01:20:48 +0800 | [diff] [blame] | 9 | - reg : the register and size of this local arbiter. |
| 10 | - mediatek,smi : a phandle to the smi_common node. |
| 11 | - power-domains : a phandle to the power domain of this local arbiter. |
| 12 | - clocks : Must contain an entry for each entry in clock-names. |
| 13 | - clock-names: must contain 2 entries, as follows: |
| 14 | - "apb" : Advanced Peripheral Bus clock, It's the clock for setting |
| 15 | the register. |
| 16 | - "smi" : It's the clock for transfer data and command. |

| 18 | Example: |
| 19 | larb1: larb@16010000 { |
| 20 | compatible = "mediatek,mt8173-smi-larb"; |
| 21 | reg = <0 0x16010000 0 0x1000>; |
| 22 | mediatek,smi = <&smi_common>; |
| 23 | power-domains = <&scpsys MT8173_POWER_DOMAIN_VDEC>; |
| 24 | clocks = <&vdecsys CLK_VDEC_CKEN>, |
| 25 | <&vdecsys CLK_VDEC_LARB_CKEN>; |
| 26 | clock-names = "apb", "smi"; |
| 27 | }; |
