Hello,

     I'm trying to debug a btwifi module via imx6ulevk's sdio. And I want to use the sdio interrupts in 1-bit mode, which uses the sdio data1 pin. As for the dtb, I don't know how to set the configurations such as "interrupt-parent" and "interrupts". Are there any patches ?

     Hope your help! Thanks!

 

     ps: the defconfig of kernel have set as follows.

           CONFIG_MMC=y

           CONFIG_MMC_SDHCI=y
           CONFIG_MMC_SDHCI_PLTFM=y
           CONFIG_MMC_SDHCI_ESDHC_IMX=y
           CONFIG_MMC_BLOCK=y
