[PATCH v6 02/11] phy: rockchip: samsung-hdptx: Use usleep_range() instead of udelay()

From: Cristian Ciocaltea <hidden>
Date: 2026-01-12 23:21:01
Also in: linux-phy, linux-rockchip, lkml
Subsystem: arm/rockchip soc support, generic phy framework, the rest · Maintainers: Heiko Stuebner, Vinod Koul, Linus Torvalds

rk_hdptx_dp_reset() is allowed to sleep, hence replace the busy waiting
with usleep_range(), to allow other threads to run.
