| 15 | |
| 16 | gsc_0: gsc@0x13e00000 { |
| 17 | compatible = "samsung,exynos5-gsc"; |
| 18 | reg = <0x13e00000 0x1000>; |
| 19 | interrupts = <0 85 0>; |
| 20 | }; |
| 21 | |
| 22 | Aliases: |
| 23 | Each G-Scaler node should have a numbered alias in the aliases node, |
| 24 | in the form of gscN, N = 0...3. G-Scaler driver uses these aliases |
| 25 | to retrieve the device IDs using "of_alias_get_id()" call. |
| 26 | |
| 27 | Example: |
| 28 | |
| 29 | aliases { |
| 30 | gsc0 =&gsc_0; |
| 31 | gsc1 =&gsc_1; |
| 32 | gsc2 =&gsc_2; |
| 33 | gsc3 =&gsc_3; |
| 34 | }; |
