Other Parts Discussed in Thread: WL1837, WL1271
Tool/software: Linux
Hi Folks,
I am getting following warning from kernel, when the module is loaded. I am using am572x and using wl1837, from the logs It seems SDIO is initialized. Just to add I have added max-frequency=<15000000>;
in the DT node, If I remove this property the SDIO interface fails to initialize [1] .
