Yes. And yes, seems to me the input driver has not reason to be in tree. The IIO should be the one to use. > > I also have patches to remove platform_data probing from ad5761, adf4350, > ad5791, ad5421 and ad5504, these all have DT support. > > See > https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=board-remove-7.4 > for the updated series. I hope to slowly get through that. Let > me know if you want me to skip any more of those patches. Thanks for taking care of this.
