[U-Boot] [PATCH v2 4/4] common/lcd_console: introduce display/framebuffer rotation
Hannes Petermaier
oe5hpm at oevsv.at
Wed Mar 18 08:37:23 CET 2015
From: Hannes Petermaier <hannes.petermaier at br-automation.com>
Sometimes, for example if the display is mounted in portrait mode or even if it
mounted landscape but rotated by 180 degrees, we need to rotate our content of
the display respectively the framebuffer, so that user can read the messages
who are printed out.
For this we introduce the feature called "CONFIG_LCD_ROTATION", this may be
defined in the board-configuration if needed. After this the lcd_console will
be initialized with a given rotation from "vl_rot" out of "vidinfo_t" which is
provided by the board specific code.
If CONFIG_LCD_ROTATION is not defined, the console will be initialized with
0 degrees rotation.

Changes in v2:
- cleanup README text for feature
- don't make code cleanups (lcd_console.c) within this patch
- remove (unnary) comment in lcd_console.h
- update year to 2015 within copyright in lcd_console.c
- move rotation related code into separate file lcd_console_rotation.c
- rework rotation code
- change meaning of vl_rot to match fbcon=rotate:<n> from the linux-kernel

+ CONFIG_LCD_ROTATION
+
+ Sometimes, for example if the display is mounted in portrait
+ mode or even if it mounted landscape but rotated by 180degree,
+ we need to rotate our content of the display respectively the
+ framebuffer, so that user can read the messages who are printed
+ out.
+ For this we introduce the feature called "CONFIG_LCD_ROTATION",
+ this may be defined in the board-configuration if needed. After
+ this the lcd_console will be initialized with a given rotation
+ from "vl_rot" out of "vidinfo_t" which is provided by the board
+ specific code.
+ The value for vl_rot is coded as following (matching to
+ fbcon=rotate:<n> linux-kernel commandline):
+ 0 = no rotation respectively 0 degree
+ 1 = 90 degree rotation
+ 2 = 180 degree rotation
+ 3 = 270 degree rotation
+
+ If CONFIG_LCD_ROTATION is not defined, the console will be
+ initialized with 0degree rotation.
+
CONFIG_LCD_BMP_RLE8
Support drawing of RLE8-compressed bitmaps on the LCD.
