The rk3288 MIPI DSI is a Synopsys DesignWare MIPI DSI host controller
IP. This series adds support for a Synopsys DesignWare MIPI DSI host
controller DRM bridge driver and a rockchip MIPI DSI specific DRM

This series also includes a DRM panel driver for BOE TV080WUM-NL0 panel.
This panel only use the MIPI DSI video mode.

The MIPI DSI feature is tested on rk3288 evb board, backport them to
chrome os kernel v3.14, and it can display normally.

This patchset is base on the patchset from Ying.liu at freescale.com.

Changes in v5:
- change the mipidsi clk to SCLK_MIPIDSI_24M
- modify the mipidsi clk name to SCLK_MIPIDSI_24M
Adviced by Thierry
- use hyphens instead of underscore
- use encoder in drm_bridge
- reformatting the dptdin table
- use readx_poll_timeout to check register
- use msleep to wait
- add a comment to explain how to program phy
- change the program code to symbolic names
- check this for validity of find_panel and clk_prepare_enable
- eliminate the configuration clock
- some optimization for coding style
- modify the clk name to SCLK_MIPIDSI_24M
- add a blank line befor lcd_en

Changes in v4:
- use clk_round_rate to check the clock rate in vop_crtc_mode_fixup
- remove the cfg clk
- remove gpr property from example, since it is noused now.
- add the description about ports
- eliminate some warnning

Changes in v3:
- move the dw_mipi_dsi.txt to Documentation/devicetree/bindings/display/bridge
- move dw_mipi_dsi_rockchip.txt to bindings/display/rockchip/

Changes in v2:
- add the mipi clk id in a single patch
