Jiri,
I will rework your patch by splitting the two lines. This will allow us
to be consistent with other AT91 SoC/boards Device Tree descriptions.
+ pinctrl-names = "default";
This one is going in the SoC file, like you did.
+ pinctrl-0 = <&pinctrl_mmc0_slot0_clk_cmd_dat0>;
This one is under the responsibility of the board itself. The reason
behind this is that the dat0 line can be multiplexed on another pin.
So, if you need a particular pinctrl configuration on the board side,
please send another patch for this addition.
Thanks bye,
