drm/amd/display: remove duplicated assignment to grph_obj_type

2020-03-18T06:17:50+00:00

commit d785476c608c621b345dd9396e8b21e90375cb0e upstream. Variable grph_obj_type is being assigned twice, one of these is redundant so remove it. Addresses-Coverity: ("Evaluation order violation") Signed-off-by: Colin Ian King Signed-off-by: Alex Deucher Cc: Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: Drop DRIVER_USE_AGP

2020-03-05T15:43:43+00:00

commit 8a3bddf67ce88b96531fb22c5a75d7f4dc41d155 upstream. This doesn't do anything except auto-init drm_agp support when you call drm_get_pci_dev().

amdgpu: Prevent build errors regarding soft/hard-float FP ABI tags

2020-03-05T15:43:39+00:00

[ Upstream commit 416611d9b6eebaeae58ed26cc7d23131c69126b1 ] On PowerPC, the compiler will tag object files with whether they use hard or soft float FP ABI and whether they use 64 or 128-bit long double ABI. On systems with 64-bit long double ABI, a tag will get emitted whenever a double is used, as on those systems a long double is the same as a double. This will prevent linkage as other files are being compiled with hard-float. On ppc64, this code will never actually get used for the time being, as the only currently existing hardware using it are the Renoir APUs. Therefore, until this is testable and can be fixed properly, at least make sure the build will not fail. Signed-off-by: Daniel Kolesa Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amd/display: Add initialitions for PLL2 clock source

2020-03-05T15:43:38+00:00

[ 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.
