Subject: [PATCH v3 05/14] phy: rockchip: samsung-hdptx: Use usleep_range() instead of udelay()
Date: Mon, 18 Aug 2025 21:59:05 +0300 [thread overview]
Message-ID: <20250818-phy-hdptx-frl-v3-5-c79997d8bb2b@collabora.com> (raw)
In-Reply-To: <20250818-phy-hdptx-frl-v3-0-c79997d8bb2b@collabora.com>
rk_hdptx_dp_reset() is allowed to sleep, hence replace the busy waiting
with usleep_range(), to allow other threads to run.
