IMX6ULL GPIO device tree customization

vasudhevan — Mon, 14 Oct 2019 18:17:32 GMT

I referred many community links not fully understood.

I checked with sd card detect pin it's working fine.

It's compulsory uboot device tree also needs to modify ?
Both uboot and kernel device tree should be same ?
Can i get example kernel device tree structure for gpio and input button customization ?
How this customization imx gpio device driver knows and how its working ?

Regards

Vasu

Hi Vasu

it is not necessary to use uboot device tree and general overview for both can be found on web:

arm - Why Device Tree Structure (DTS) file is needed both in bootloader and kernel source code? - Stack Overflow

for gpio and device tree customization one can look on
