Similar to previous Rockchip SoCs, reset controller on RK3528 shares MMIO region with clock controller, combined as CRU. They're represented as a single node in dt. For the reset controller, only bindings are included in this series because it's hard to test the reset controller without support for some peripherals (e.g. pinctrl). I'd like to first make dt and basic peripherals available, then submit the driver. This is tested on Radxa E20C board. With some out-of-tree drivers, I've successfully brouhgt up UART, pinctrl/gpio and I2C. A clock dump could be obtained from [1].
