Hi all,
The current i2c-gpio DT bindings use a single unnamed "gpios" property
to refer to the SDA and SCL signal lines by index. This is error-prone
for the casual DT writer and reviewer, as one has to look up the order
in the DT bindings, and leads to the addition of comments in DTS files,
like
gpios = <&pfc 208 GPIO_ACTIVE_HIGH /* sda */
&pfc 91 GPIO_ACTIVE_HIGH /* scl */
>;
This patch series:
- Amends the DT bindings to use named gpios,
- Adds support for the new bindings to the driver,
- Converts the armadillo800eva to use the new bindings, as an example.
Thanks for your comments!
