Thank you for the review, I'm thinking of splitting this commit into several smaller ones: - remove all status = "okay" things and i2c aliases - remove sdmmc-ecc node (it's a part of the Arria 10 SoC, not the mercury) - add atsha204a node - add copyright header - style fixes (phy reg, memory) What do you think? Please see my other comments below.

I'm removing them from here, but adding them to socfpga_arria10_chameleonv3.dts. I think that enabling them should be done in the base board's dts, as the connections go to the base board. The Chameleon v3 has a USB port, but a different base board might not have one. > > > - > > &i2c1 { > > - status = "okay"; > > + atsha204a: atsha204a@64 { > > How is this change related at all to what you described in commit?
