Subject: [PATCH AUTOSEL 5.5 26/58] drm/amd/display: Add initialitions for PLL2 clock source
Date: Sat, 22 Feb 2020 21:20:47 -0500	[thread overview]
Message-ID: <20200223022119.707-26-sashal@kernel.org> (raw)
In-Reply-To: <20200223022119.707-1-sashal@kernel.org>

From: Isabel Zhang <isabel.zhang@amd.com>

[ Upstream commit c134c3cabae46a56ab2e1f5e5fa49405e1758838 ]

[Why]
Starting from 14nm, the PLL is built into the PHY and the PLL is mapped
to PHY on 1 to 1 basis. In the code, the DP port is mapped to a PLL that was not
initialized. This causes DP to HDMI dongle to not light up the display.

[How]
Initializations added for PLL2 when creating resources.
