Hi all, The IO domains on Rockchip SoCs need to be configured to the correct bank voltage. In Linux this is achieved by means of a platform driver that reads the voltage value of the supplies and configures the bits in the general register file (GRF) accordingly. This series ports this driver to barebox to provide support for the Rockchip RK356x SoCs. Please note that I could only test the changes on RK3568 boards, so I left out the parts for the other SoCs supported by the Linux driver. Also, it should be noted that the Linux driver uses notifiers to react to voltage changes. This is not supported by this barebox driver. WARNING: Use those patches with care as they have the potential to fry up your board. That said, testers are very welcome ;-) Looking forward to your comments!
