[PATCH 1/1] phy: rockchip: naneng-combphy: compatible with old DT for RK3568
From: Chukun Pan <hidden>

Subsystem:
arm/rockchip soc support, generic phy framework, the rest · Maintainers:
Heiko Stuebner, Vinod Koul, Linus Torvalds
The device tree of RK3568 did not specify reset-names before.
So add fallback to old behaviour to be compatible with old DT.
