2014-09-05exynos_fb: Remove usage of static definesAjay Kumar
Previously, we used to statically assign values for vl_col, vl_row and vl_bpix using #defines like LCD_XRES, LCD_YRES and LCD_COLOR16. Introducing the function exynos_lcd_early_init() would take care of this assignment on the fly by parsing FIMD DT properties, thereby allowing us to remove LCD_XRES and LCD_YRES from the main config file.

2014-08-11video: ipu_disp: squash clang warningJeroen Hofstee
Since rgb2ycbcr_coeff and friends are declared const, but assigned to a void pointer, clang will warn that the const is implicity casted away. If the pointer is changed to void const * gcc will warn when it is implicitly casted to a const int array. Just add a correctly typed pointer instead to prevent these casts and hence the warnings.

2014-08-11video: ipu_disp: wait for DP SF end irq when disabling sync BG flowsLiu Ying
Instead of waiting for DC triple buffer to be cleared, this patch changes to wait for a relevant DP sync flow end interrupt to come when disabling sync BG flows. In this way, we align the implement to the freescale internal IPUv3 driver. After applying this patch, an uboot hang up issue at the arch_preboot_os() stage, where we disable a relevant ipu display channel, is not observed any more on some MX6DL platforms.

2014-07-23stdio: Pass device pointer to stdio methodsSimon Glass
At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>
2014-07-23stdio: Remove redundant code around stdio_register() callsSimon Glass
There is no point in setting a structure's memory to NULL when it has already been zeroed with memset(). Also, there is no need to create a stub function for stdio to call - if the function is NULL it will not be called. This is a clean-up, with no change in functionality.

2014-03-10cfb_console: align fields in gzipped .bmp filesEric Nelson
.bmp files contain 32-bit integers aligned at offsets of +2, +6, et cetera within the bmp_header structure (see include/bmp_layout.h). Support for gzip-compressed .bmp files is present in the cfb_console display subsystem by uncompressing them prior to use. This patch forces the in-memory header to be aligned properly for these compressed images by extracting them to a 2-byte offset in the memory returned by malloc. Since malloc will always return a 4-byte aligned value, this forces the .bmp header fields to be naturally aligned on 4-byte addresses. Refer to these files for more details: doc/README.displaying-bmps Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>
