2013-03-21lcd, amba: remove this driver since it is not usedJeroen Hofstee
Since CONFIG_VIDEO_AMBA is not set by any board, it does not seem to be used, so remove it since there is no way to (compile) test it. cc: Alessandro Rubini <rubini@unipv.it> cc: Anatolij Gustschin <agust@denx.de> Acked-by: Alessandro Rubini <rubini@unipv.it> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
2013-03-21common/lcd.c: cleanup use of global variablesWolfgang Denk
lcd_color_fg and lcd_color_bg had to be declared in board specific code, but were not actually used there; in addition, we have getter / setter functions for these, which were not used either. Get rid of the global variables, and use the getter function where needed (so far no setter calls are needed).

2013-03-20video: add a driver for the bcm2835Stephen Warren
The firmware running on the bcm2835 SoC's VideoCore CPU manages the display controller. Add a simple "LCD" driver that communicates with the firmware using the property mailbox protocol. This configures the display and frame-buffer to match whatever physical resolution the firmware chosen when booting, which is typically the native resolution of the attached display device, presumably unless otherwise specified in config.txt on the boot media. Enable this driver in the Raspberry Pi board configuration. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2013-03-08omap3: allow dynamic selection of gfx_formatNikita Kiryanov
Currently, omap3_dss_panel_config() sets gfx_format to a value that is hardcoded in the code. This forces anyone who wants to use a different gfx_format to make adjustments after calling omap3_dss_panel_config(). This could be avoided if the value of gfx_format were parameterized as input for omap3_dss_panel_config(). Make gfx_format a field in struct panel_config, and update existing structs to set this field to the value that was originally hard coded.

2013-01-16video: tegra: Update line length to match resolutionThierry Reding
Instead of storing the computed line length in a local variable, store it in the global lcd_line_length variable to make sure the LCD subsystem can properly draw content for the display resolution. This probably wasn't noticed yet because the only board where LCD support is currently enabled is Seaboard, which runs at a 1366x768 resolution. As it happens this is the maximum resolution supported and also the default that is used to initialize the framebuffer before the configuration from DT is available.

2013-01-14video: exynos_fb: Make a call to draw_logo only when CONFIG_CMD_BMP is selectedAjay Kumar
Previously, the call to draw_logo() was happening irrespective of whether we have selected logo or LCD console. With this patch we call draw_logo() only when CONFIG_CMD_BMP is selected. This would even fix the following compilation warning: exynos_fb.c: In function 'draw_logo': exynos_fb.c:74:8: warning: variable 'addr' set but not used [-Wunused-but-set-variable] exynos_fb.c:73:9: warning: variable 'y' set but not used [-Wunused-but-set-variable] exynos_fb.c:73:6: warning: variable 'x' set but not used [-Wunused-but-set-variable] Signed-off-by: Ajay Kumar <ajaykumar.rs@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

2013-01-10video: Modify exynos_fimd driver to support LCD consoleAjay Kumar
Currently, exynos FIMD driver is being used to support only TIZEN LOGOs. In order to get LCD console, we need to enable half word swap feature of FIMD and use 16 BPP. LCD console and proprietary Logo cannot be used simultaneously. We use "logo_on" field inside vidinfo_t structure to decide whether user wants Logo or Console. Define CONFIG_CMD_BMP and make logo_on = 1 to get Logo on screen. Use logo_on = 0 to get output console on LCD.

Several DIU registers were being initialized either unnecessarily or to wrong values. 1) All interrupts were enabled even though there's no interrupt handler. Interrupts were left enabled when booting Linux. 2) Don't configure a dummy area descriptor, since we don't support ADs in U-Boot. 3) Don't configure any write-back buffer registers, since we don't use that mode. 4) The default values for the THRESHOLDS, SYN_POL, and PLUT registers should be used, so don't touch those registers either.
