OMAPDSS: DISPC: add no_framedone_tv feat
OMAP2/3 do not have FRAMEDONETV irq, but later omaps do. We currently always return 0 from dispc_mgr_get_framedone_irq() for TV output to be compatible with OMAP2/3. This patch implements "no_framedone_tv" dispc-feature that is used in dispc_mgr_get_framedone_irq to return either 0 for OMAP2/3, or the correct IRQ number for FRAMEDONETV on OMAP4+. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
