A while back, the sunxi-specific P2WI and RSB drivers were converted to support DM_I2C. Now they are used as non-DM drivers in SPL, and DM drivers in U-Boot proper.
However, the DM version of the code did not fully initialize either the controller or the connected chips. So the DM driver would only work if the non-DM version had previously been used in SPL.
With these bug fixes and the pinctrl series, the drivers now work on SoCs like A64 and H6, which have a PMIC but do not set it up in SPL.
