Internal Pull Down of Pin154

Technical Support queries

Hi Team,

I am configuring the SD Card interface but I noticed that the pin 154 of Apalis imx8 is having an internal pull down while other sd signals are having internal pull up in imx8-apalis-v1.1.dtsi.
https://git.toradex.com/cgit/linux-toradex.git/tree/arch/arm64/boot/dts/freescale/imx8-apalis-v1.1.dtsi?h=toradex_5.4-2.3.x-imx#n725
For bit 5 and 6:
00b - prohibited
01b - pull-up
10b - pull-down
11b - pull disabled


Looking at 0x06000041 (0110000000000000000001000001), where bit 5 and 6 is10b right? May I know why this pin needs to set differently from other pin?

Thank you!

Pin 154 is the CLK line and according to SDIO physical layer specification it should be pulled down.

Noted. Thank you!
