[PATCH 5.12 041/700] ARM: dts: ux500: Fix LED probing

From: Greg Kroah-Hartman
Date: Mon Jul 12 2021 - 03:20:30 EST


From: Linus Walleij <linus.walleij@xxxxxxxxxx>

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.
