| Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame] | 1 | * Nuvoton NPCM KCS (Keyboard Controller Style) IPMI interface |
| 2 | |
| 3 | The Nuvoton SOCs (NPCM) are commonly used as BMCs |
| 4 | (Baseboard Management Controllers) and the KCS interface can be |
| 5 | used to perform in-band IPMI communication with their host. |
| 6 | |
| 7 | Required properties: |
| 8 | - compatible : should be one of |
| 9 | "nuvoton,npcm750-kcs-bmc" |
| 10 | "nuvoton,npcm845-kcs-bmc", "nuvoton,npcm750-kcs-bmc" |
| 11 | - interrupts : interrupt generated by the controller |
| 12 | - kcs_chan : The KCS channel number in the controller |
| 13 | |
| 14 | Example: |
| 15 | |
| 16 | lpc_kcs: lpc_kcs@f0007000 { |
| 17 | compatible = "nuvoton,npcm750-lpc-kcs", "simple-mfd", "syscon"; |
| 18 | reg = <0xf0007000 0x40>; |
| 19 | reg-io-width = <1>; |
| 20 | |
| 21 | #address-cells = <1>; |
| 22 | #size-cells = <1>; |
| 23 | ranges = <0x0 0xf0007000 0x40>; |
| 24 | |
| 25 | kcs1: kcs1@0 { |
| 26 | compatible = "nuvoton,npcm750-kcs-bmc"; |
| 27 | reg = <0x0 0x40>; |
| 28 | interrupts = <0 9 4>; |
| 29 | kcs_chan = <1>; |
| 30 | status = "disabled"; |
| 31 | }; |
| 32 | |
| 33 | kcs2: kcs2@0 { |
| 34 | compatible = "nuvoton,npcm750-kcs-bmc"; |
| 35 | reg = <0x0 0x40>; |
| 36 | interrupts = <0 9 4>; |
| 37 | kcs_chan = <2>; |
| 38 | status = "disabled"; |
| 39 | }; |
| 40 | }; |
