2012-09-22video: exynos_mipi_dsi: Remove unnecessary NULL checkSachin Kamat
'dsim' is allocated and checked for NULL in the probe function. Hence this check is redundant. This cleanup also fixes a potential NULL pointer dereference error when dsim which is NULL references its member in the error print message.

2012-05-13video: exynos mipi dsi: Properly interpret the interrupt source flagsSylwester Nawrocki
Rework the interrupt handler so the RX_DONE, FIFO_EMPTY interrupts are properly detected. This prevents missing the interrupts when there are other bits set in the INTSRC register than just RX_DONE and FIFO_EMPTY.

2012-04-24fb: exynos: Fix MIPI/DSI front/back porch settingsLaurent Pinchart
The exynos_mipi_dsi_set_main_disp_[hv]porch() functions take front and back porch arguments in that order. This maps to the fb_videomode right/lower_margin and left/upper_margin respectively. Fix the caller accordingly. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Donghwa Lee <dh09.lee@samsung.com>
2012-02-13video: support MIPI-DSI controller driverDonghwa Lee
Samsung S5PC210 and EXYNOS SoC platform has MIPI-DSI controller and MIPI-DSI based LCD Panel could be used with it. This patch supports MIPI-DSI driver based Samsung SoC chip. LCD panel driver based MIPI-DSI should be registered to MIPI-DSI driver at machine code and LCD panel driver specific function registered to mipi_dsim_ddi structure at lcd panel init function called system init. In the MIPI-DSI driver, find lcd panel driver by using registered lcd panel name, and then initialize lcd panel driver.
