drm/i915: Initialize panel timing registers if VBIOS did not
The time between start of the pixel clock and backlight enable is a basic panel timing constraint. If the Panel Power On/Off registers are found to be 0, assume we are booting without VBIOS initialization and set these registers to something reasonable. Change-Id: Ibed6cc10d46bf52fd92e0beb25ae3525b5eef99d Signed-off-by: Bryan Freed <bfreed@chromium.org> [ickle: rearranged into a separate function to distinguish its role from simply parsing the VBIOS tables.] Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
