Shouldn't be preferrable to group the two functions in a single one,
I agree. It is better.
            usart1_pins_a: usart1@0 {
                pins1 {
                    pinmux = <STM32F429_PA9_FUNC_USART1_TX>;
                    bias-disable;
                    drive-push-pull;
                    slew-rate = <0>;
                };
                pins2 {
                    pinmux = <STM32F429_PA10_FUNC_USART1_RX>;
                    bias-disable;
                };
            };

Also, I would prefer the phandle to be suffixed with the port number,
as multiple muxing options are available, for example "i2c1_pins_b".
Ok understood. I will fix that in the V3.
Thanks
Thanks,
Maxime
