Subject: [PATCH] ARM: dts: ux500: Fix LED probing
Date: Sun, 13 Jun 2021 14:33:56 +0200	[thread overview]
Message-ID: <20210613123356.880933-1-linus.walleij@linaro.org> (raw)

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.

Fixes: 92a81562e695 ("leds: lp55xx: Add multicolor framework support to lp55xx")
