Subject: [PATCH AUTOSEL 5.17 03/43] drm/amd/display: Read Golden Settings Table from VBIOS
Date: Mon, 13 Jun 2022 22:05:22 -0400 [thread overview]
Message-ID: <20220614020602.1098943-3-sashal@kernel.org> (raw)
In-Reply-To: <20220614020602.1098943-1-sashal@kernel.org>
From: Sherry Wang <YAO.WANG1@amd.com>
[ Upstream commit 4b81dd2cc6f4f4e8cea0ed6ee8d5193a8ae14a72 ]
[Why]
Dmub read AUX_DPHY_RX_CONTROL0 from Golden Setting Table,
but driver will set it to default value 0x103d1110, which
causes issue in some case
[How]
Remove the driver code, use the value set by dmub in
dp_aux_init
