Hi Quentin, Thanks for review, this is the first time I've submitted a patch to u-boot. I referred to some other rk3568 boards that had the clock name removed, so I left it as it was. There was no problem with the board starting, and I don't know why them remove clocks name. The board is working fine. Best, Coia
