Subject: [PATCH 0/3] drm/imx: convey the pixelclk-active and de-active flags 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.
Use an open coded version of of_get_drm_display_mode() to get access
to these flags and make sure they are passed on to the ipu-di driver.
This patch also makes sure, that the 'bus_flags' specified in the
simple-panel driver will be passed on from the ipu-di driver.

The first patch in this series makes sure, the imx-ldb driver honors
the 'native-mode' property in DT (like the parallel-display driver
does already).

The third patch removes some dead code in the parallel-display driver,
hat depends on a variable which is never assigned a non-zero value and
thus can never be reached.
