2012-05-08video: EXYNOS: enable interrupt again after sw resetDonghwa Lee1-0/+2
When exynos_mipi_update_cfg() is called, mipi dsi registers were become sw reset. So, It needs to enable interrupt again.

2012-04-24fb: exynos: Fix MIPI/DSI front/back porch settingsLaurent Pinchart1-4/+4
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>
2012-04-16video: exynos_dp: add analog and pll control settingJingoo Han3-0/+53
This patch adds analog and pll control setting. This control setting is used for DP TX PHY block to set the values as below. It is beneficial to improve analog characteristics. - TX terminal registor is 50 Ohm. - Reference clock of PHY is 24 MHz. - Power source for TX digital logic is 1.0625 V. - Power source for internal clock driver is 1.0625 V. - PLL VCO range setting is 600 uA. - Power down ring osc is turned off. - AUX terminal resistor is 50 Ohm. - AUX channel current is 8 mA and multiplied by 2. - TX channel output amplitude is 400 mV.

2012-02-13video: backlight: support s6e8ax0 panel driver based on MIPI DSIDonghwa Lee4-1/+929
An moled panel driver based MIPI DSI interface. S6E8AX0 means it may includes many other ldi controllers, for example, S6E8AA0, S6E8AB0, and so on. This patch can be modified depending on each panel properites. For example, second parameter of panel condition register can be changed depending on ldi controller or amoled type.

2012-02-13video: support MIPI-DSI controller driverDonghwa Lee8-0/+2449
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.
