Subject: [PATCH AUTOSEL 6.14 19/31] phy: rockchip: usbdp: Avoid call hpd_event_trigger in dp_phy_init
Date: Mon,  7 Apr 2025 14:10:35 -0400	[thread overview]
Message-ID: <20250407181054.3177479-19-sashal@kernel.org> (raw)
In-Reply-To: <20250407181054.3177479-1-sashal@kernel.org>

From: Andy Yan <andy.yan@rock-chips.com>

[ Upstream commit 28dc672a1a877c77b000c896abd8f15afcdc1b0c ]

Function rk_udphy_dp_hpd_event_trigger will set vogrf let it
trigger HPD interrupt to DP by Type-C. This configuration is only
required when the DP work in Alternate Mode, and called by
typec_mux_set. In standard DP mode, such settings will prevent
the DP from receiving HPD interrupts.
