[PATCH 0/5] Support RK3528 variant of Rockchip naneng-combphy

[Yao Zi <ziyao@disroot.org>]

Rockchip RK3528 ships a naneng-combphy that operates in either PCIe or
USB 3.0 mode. It has a similar control logic to previous generations of
naneng-combphy but an apparently different register layout.

This series prepares phy-rockchip-naneng-combphy.c for variants with a
different register layout and add RK3528 support.

Testing is done on both Radxa E20C and Radxa Rock 2A with downstream
devicetree changes, both USB 3 and PCIe modes are verified with mainline
driver and achives a reasonable link speed.

The devicetree change (PATCH 5) depend on v5 of the SD/SDIO series
("Support SD/SDIO controllers on RK3528")[1] for a clean apply. Thanks
for your time and review.
