| Subject: dt-bindings: i2c: at91: fix example for scl-gpios |
| |
| From: Nicolas Ferre <nicolas.ferre@microchip.com> |
| |
| [ Upstream commit 92e669017ff1616ba7d8ba3c65f5193bc2a7acbe ] |
| |
| 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"). |
