[PATCHv4 0/3] drm/imx: convey the pixelclk-active and de-active flags from DT to the ipu-di driver

The 'de-active' and 'pixelclk-active' DT properties are evaluated by of_parse_display_timing() called from of_get_drm_display_mode(), but later lost in the conversion from videomode.flags to drm_display_mode.flags.

Changes vs. v3: - split the patch as suggested by Daniel Vetter

Changes vs. v2: - removed patches which have already been applied - created a drm_bus_flags_from_videomode() helper to prevent code duplication as suggested by Philipp Zabel

Changes vs. v1: - rebased on top of https://patchwork.kernel.org/patch/9113791/ as per Philipp Zabel's request
