Subject: [PATCH 5.10 18/83] ARM: dts: imx6dl-yapp4: Fix lp5562 LED driver probe
Date: Mon, 11 Oct 2021 15:45:38 +0200 [thread overview]
Message-ID: <20211011134508.981609489@linuxfoundation.org> (raw)
In-Reply-To: <20211011134508.362906295@linuxfoundation.org>
From: Michal Vokáč <michal.vokac@ysoft.com>
commit 9b663b34c94a78f39fa2c7a8271b1f828b546e16 upstream.
Since the LED multicolor framework support was added in commit
92a81562e695 ("leds: lp55xx: Add multicolor framework support to lp55xx")
LEDs on this platform stopped working.
Author of the framework attempted to accommodate this DT to the
framework in commit b86d3d21cd4c ("ARM: dts: imx6dl-yapp4: Add reg property
to the lp5562 channel node") but that is not sufficient. A color property
is now required even if the multicolor framework is not used, otherwise
the driver probe fails:
lp5562: probe of 1-0030 failed with error -22
Add the color property to fix this.
Fixes: 92a81562e695 ("leds: lp55xx: Add multicolor framework support to lp55xx")
