Subject: [PATCH] dt-bindings: i2c: at91: fix example for scl-gpios
Date: Fri, 4 Jun 2021 15:24:38 +0200 [thread overview]
Message-ID: <20210604132438.18784-1-nicolas.ferre@microchip.com> (raw)
From: Nicolas Ferre <nicolas.ferre@microchip.com>
The SCL gpio pin used by I2C bus for recovery needs to be configured as
open drain, so fix the binding example accordingly.
In relation with fix c5a283802573 ("ARM: dts: at91: Configure I2C SCL
gpio as open drain").
Signed-off-by: Nicolas Ferre <nicolas.ferre@microchip.com>
Fixes: 19e5cef058a0 ("dt-bindings: i2c: at91: document optional bus recovery properties")
