2014-11-25sunxi: video: Add simplefb supportLuc Verhaegen
Add simplefb support, note this depends on the kernel having support for the clocks property which has recently been added to the simplefb devicetree binding.

2014-11-25sunxi: video: Add sun6i supportHans de Goede

2014-11-25sunxi: video: Add cfb console driver for sunxiLuc Verhaegen
This adds a fixed mode hdmi driver for the sunxi platform. The fixed mode is a relatively safe 1024x768, more complete EDID handling is currently not provided. Only HDMI is supported today. This code is enabled when HPD detects an attached monitor. Current config is such that 8MB is shaved off at the top of the RAM. This avoids several memory handling issues, most significant is the fact that on linux on ARM you are not allowed to remap known RAM as IO. A clued in display driver will be able to recycle this reserved RAM in future though. cfbconsole was chosen as it provides the most important functionality: a working u-boot console, allowing for the debugging of certain issues without the need for a UART.

2014-11-23linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada
U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>
2014-11-20include: move various macros to include/linux/kernel.hMasahiro Yamada
U-Boot has imported various utility macros from Linux scattering them to various places without consistency. In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN, container_of, DIV_ROUND_UP, etc. In include/linux/compat.h are min_t, max_t, round_up, round_down, etc. We also have duplicated defines of min_t in some *.c files. Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position. Note: This commit simply moves the macros; the macros roundup, min, max, min2, max3, ARRAY_SIZE are different from those of Linux at this point.

2014-10-16video: ipu_disp: remove pixclk fixupJeroen Hofstee
The ipu display insists on having a lower_margin smaller then 2. If this is not the case it will attempt to force it and adjust the pixclk accordingly. This multiplies pixclk in Hz with the width and height, since this is typically a * 10^7 * b * 10^2 * c * 10^2 this will overflow the uint_32 and make things even worse. Since this is a bootloader and the adjustment is neglectible, just force it to two and warn about it. Cc: Stefano Babic <sbabic@denx.de> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

On Exynos5420 and newer versions, the FIMD sysmmus are in "on state" by default. We have to disable them in order to make FIMD DMA work.

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.
