Normally display is black on white background; define
CONFIG_SYS_WHITE_ON_BLACK to get it inverted.
+ CONFIG_LCD_ALIGNMENT
+
+ Normally the LCD is page-aligned (tyically 4KB). If this is
+ defined then the LCD will be aligned to this value instead.
+ For ARM it is sometimes useful to use MMU_SECTION_SIZE
+ here, since it is cheaper to change data cache settings on
+ a per-section basis.
+
+ CONFIG_CONSOLE_SCROLL_LINES
+
+ When the console need to be scrolled, this is the number of
+ lines to scroll by. It defaults to 1. Increasing this makes
+ the console jump but can help speed up operation when scrolling
+ is slow.
+
CONFIG_LCD_BMP_RLE8
Support drawing of RLE8-compressed bitmaps on the LCD.
Enables an 'i2c edid' command which can read EDID
information over I2C from an attached LCD display.

+Tegra SoC PWFM controller
+
+Required properties:
+- compatible: should be one of:
+ - "nvidia,tegra20-pwm"
+ - "nvidia,tegra30-pwm"
+- reg: physical base address and length of the controller's registers
+- #pwm-cells: On Tegra the number of cells used to specify a PWM is 2. The
+ first cell specifies the per-chip index of the PWM to use and the second
+ cell is the period in nanoseconds.
+
+Example:
+
+ pwm: pwm@7000a000 {
+ compatible = "nvidia,tegra20-pwm";
+ reg = <0x7000a000 0x100>;
+ #pwm-cells = <2>;

+videomode bindings
+==================
+
+(from http://lists.freedesktop.org/archives/dri-devel/2012-July/024875.html)
+
+Required properties:
+ - xres, yres: Display resolution
+ - left-margin, right-margin, hsync-len: Horizontal Display timing
+ parameters in pixels
+ - upper-margin, lower-margin, vsync-len: Vertical display timing
+ parameters in lines
+ - clock: display clock in Hz
+
+Optional properties:
+ - width-mm, height-mm: Display dimensions in mm
+ - hsync-active-high (bool): Hsync pulse is active high
+ - vsync-active-high (bool): Vsync pulse is active high
+ - interlaced (bool): This is an interlaced mode
+ - doublescan (bool): This is a doublescan mode
+
+There are different ways of describing a display mode. The devicetree
+representation corresponds to the one used by the Linux Framebuffer
+framework described here in Documentation/fb/framebuffer.txt. This
+representation has been chosen because it's the only format which does
+not allow for inconsistent parameters. Unlike the Framebuffer framework
+the devicetree has the clock in Hz instead of ps.
+
+Example:
+
+ display@0 {
+ /* 1920x1080p24 */
+ clock = <52000000>;
+ xres = <1920>;
+ yres = <1080>;
+ left-margin = <25>;
+ right-margin = <25>;
+ hsync-len = <25>;
+ lower-margin = <2>;
+ upper-margin = <2>;
+ vsync-len = <2>;

+Display Controller
+------------------
+
+(there isn't yet a generic binding in Linux, so this describes what is in
+U-Boot, and may change based on Linux activity)
+
+The device node for a display device is as described in the document
+"Open Firmware Recommended Practice : Universal Serial Bus" with the
+following modifications and additions :
+
+Required properties :
+ - compatible : Should be "nvidia,tegra20-dc"
+
+Required subnode 'rgb' is as follows:
+
+Required properties (rgb) :
+ - nvidia,panel : phandle of LCD panel information
+
+
+The panel node describes the panel itself. This has the properties listed in
+displaymode.txt as well as:
+
+Required properties (panel) :
+ - nvidia,bits-per-pixel: number of bits per pixel (depth)
+ - nvidia,pwm : pwm to use to set display contrast (see tegra20-pwm.txt)
+ - nvidia,panel-timings: 4 cells containing required timings in ms:
+ * delay before asserting panel_vdd
+ * delay between panel_vdd-rise and data-rise
+ * delay between data-rise and backlight_vdd-rise
+ * delay between backlight_vdd and pwm-rise
+ * delay between pwm-rise and backlight_en-rise
+
+Optional GPIO properies all have (phandle, GPIO number, flags):
+ - nvidia,backlight-enable-gpios: backlight enable GPIO
+ - nvidia,lvds-shutdown-gpios: LVDS power shutdown GPIO
+ - nvidia,backlight-vdd-gpios: backlight power GPIO
+ - nvidia,panel-vdd-gpios: panel power GPIO
+
