| Subject: ARM: dts: ux500: Fix LED probing |
| |
| From: Linus Walleij <linus.walleij@linaro.org> |
| |
| commit 7749510c459c10c431d746a4749e7c9cf2899156 upstream. |
| |
| The Ux500 HREF LEDs have not been probing properly for a |
| while as this was introduce: |
| |
| ret = of_property_read_u32(np, "color", &led_color); |
| if (ret) |
| return ret; |
| |
| Since the device tree did not define the new invented color |
| attribute, probe was failing. |
| |
| Define color attributes for the LEDs so they work again. |
