| 3 | Required properties: |
| Hans de Goede | 915974c | 2014-02-11 17:35:29 +0100 | [diff] [blame] | 4 | - compatible : should be "generic-ehci". |
| Kumar Gala | b053dc5 | 2009-06-19 08:31:05 -0500 | [diff] [blame] | 5 | - reg : should contain at least address and length of the standard EHCI |
| 6 | register set for the device. Optional platform-dependent registers |
| 7 | (debug-port or other) can be also specified here, but only after |
| 8 | definition of standard EHCI registers. |
| 9 | - interrupts : one EHCI interrupt should be described here. |

| 11 | Optional properties: |
| 12 | - big-endian-regs : boolean, set this for hcds with big-endian registers |
| 13 | - big-endian-desc : boolean, set this for hcds with big-endian descriptors |
| 14 | - big-endian : boolean, for hcds with big-endian-regs + big-endian-desc |

| 17 | Translator built into the root hub. |
| Hans de Goede | a4aeb21 | 2014-02-07 16:36:41 +0100 | [diff] [blame] | 18 | - clocks : a list of phandle + clock specifier pairs |
