From: Paul Kocialkowski Date: Wed, 6 Nov 2019 09:43:59 +0000 (+0100) Subject: drm/gma500: Add missing call to allow enabling vblank on psb/cdv X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b20e9afb38d0b7f407bde1f9a4f5080626666482;p=linux.git drm/gma500: Add missing call to allow enabling vblank on psb/cdv This adds a missing call to drm_crtc_vblank_on to the common DPMS helper (used by poulsbo and cedartrail), which is called in the CRTC enable path. With that call, it becomes possible to enable vblank when needed. It is already balanced by a drm_crtc_vblank_off call in the helper. Other platforms (oaktrail and medfield) use a dedicated DPMS helper that does not have the proper vblank on/off hooks. They are not added in this commit due to lack of hardware to test it with.
