During the building of secoA62 image i'm looking to the device tree (i'm newbie on this, i just discover it this week end ) of A62 to check if spi is enabled. I found this file imx6dl-seco_SBC_A62.dts and this one imx6qdl-seco_SBC_A62.dtsi . On the second link, they have 2 spi defined (line 267). ecspi1 and ecspi3. After on line 478 they define more precisely (if i'm not wrong !) . I would like to use a spi on gpio port, see under ECSPI2, not define on dtsi, how i can do that ?
