[PATCH v15 05/12] drm: imx: imx-hdmi: move imx-hdmi to bridge/dw_hdmi
From: Andy Yan
Date: Tue Dec 02 2014 - 02:42:04 EST
the original imx hdmi driver is under drm/imx/,
which depends on imx-drm, so move the imx hdmi
driver out to drm/bridge and rename it to dw_hdmi
Signed-off-by: Andy Yan <andy.yan@xxxxxxxxxxxxxx>
---
Changes in v15:
- add prefix dw_hdmi/DW_HDMI for public used dw_hdmi structs
adviced by Philipp Zabel
- remove THIS_MODULE in platform driver
