Add pullup on mmc2 data signals in the > same way it was previously done for mmc0 and mmc1. > > Signed-off-by: Sylvain Rochet Acked-by: Nicolas Ferre Thanks Sylvain! > --- > arch/arm/boot/dts/sama5d3_mci2.dtsi | 6 +++--- > 1 file changed, 3 insertions(+), 3 deletions(-) > > diff --git a/arch/arm/boot/dts/sama5d3_mci2.dtsi b/arch/arm/boot/dts/sama5d3_mci2.dtsi > index 026b252..e21099a 100644 > --- a/arch/arm/boot/dts/sama5d3_mci2.dtsi > +++ b/arch/arm/boot/dts/sama5d3_mci2.dtsi > @@ -24,9 +24,9 @@ > }; > pinctrl_mmc2_dat1_3: mmc2_dat1_3 { > atmel,pins = > - - AT91_PIOC 13 AT91_PERIPH_A AT91_PINCTRL_NONE /* PC13 periph A MCI2_DA2 with pullup, conflicts with TIOB1 */ > - AT91_PIOC 14 AT91_PERIPH_A AT91_PINCTRL_NONE>; /* PC14 periph A MCI2_DA3 with pullup, conflicts with TCLK1 */ > + + AT91_PIOC 13 AT91_PERIPH_A AT91_PINCTRL_PULL_UP /* PC13 periph A MCI2_DA2 with pullup, conflicts with TIOB1 */ > + AT91_PIOC 14 AT91_PERIPH_A AT91_PINCTRL_PULL_UP>; /* PC14 periph A MCI2_DA3 with pullup, conflicts with TCLK1 */ > }; > }; > }; > -- Nicolas Ferre
