[PATCH v2 0/5] Support clock and reset unit of Rockchip RK3528

[Yao Zi <ziyao@disroot.org>]

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].
