[PATCH 0/2] soc: rockchip: add driver for rockchip io domains

[Michael Riesch]

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!

Best regards,
Michael
