bcc6cc9b37 omap3: allow dynamic selection of gfx_format
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.

0c5587549b video: tegra: Update line length to match resolution
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.

e4660e0b73 video: exynos_fb: Make a call to draw_logo only when CONFIG_CMD_BMP is selected
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

61b59e2749 video: Modify exynos_fimd driver to support LCD console
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

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.
