dh09.lee at samsung.com
Mon Sep 27 22:05:27 EDT 2010
This patch adds several machine specific header files that including
necessary structures and dsim device setup codes.
struct dsim_config
- define clock info, data lane count and video mode info for MIPI-DSI
Controller.
struct dsim_lcd_config
- define interface mode, channel ID, Pixel format and so on.
struct s5p_platform_dsim
- define callbacks for initializing D-PHY, MIPI reset and trigger
releated interfaces of s3c-fb.c file.
struct mipi_ddi_platform_data
- define following callbacks.
- a function for transferring and receiving command data to mipi based
lcd panel.
- a function for getting framedone status of mipi-dsi controller.
- a function for clearing framedone interrupt of mipi-dsi controller.
- a function for checking i80 framedone status of display controller.(fimd)
- a function for triggering to display controller.(fimd)
