Hi support,
I hope to remove the GPIO0_22(spi2_clk) pin mux iniatialize from the am437x-gp-evm.dts file. Could you please give me some help?
I set the GPIO0_22 output is high in u-boot and I hope this pin will keep output high until init my application startup in rcS file. But I found this pin will become low when booting the linux kernel. I guess this pin is initialized by tscadc module, because it use the spi2 as the data interface. I don't know how to remove this pin mux(GPIO0_22) setting from the dts file, please give me some help.
