2017-09-04video: ipuv3_fb: skip IPU shutdown if IPU was not enabled beforeAnatolij Gustschin
Boards can skip display interface init using board_video_skip(). If display interface was not initialized (e.g. no ipuv3 framebuffer registered or IPU clock disabled), booting Linux stops due to the crash in IPU shutdown function, when accessing IPU registers. Check IPU clock and skip shutdown if clock is not enabled. Signed-off-by: Anatolij Gustschin <agust@denx.de>

Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

2015-08-30video: discard empty video_set_lut implementationPeng Fan
Discard the empty video_set_lut function from platform video drivers. This commit "69d275458893eaec35229b589092c2a6bde5440f" introduces a weak function video_set_lut, so we do not need an strong function in platform drivers, which does nothing.

2014-04-30video: mxc_ipuv3_fb: stash frame buffer pointer in global data.Eric Nelson
This patch updates the i.MX video driver to store the frame-buffer address in the fb_base field of the global data structure *gd. By doing this, you can find the frame buffer address using the 'bdinfo' command: U-Boot > bdinfo arch_number = 0x00000EB9 ... FB base = 0x4F35F1C0 This is very useful when debugging display connections.

2011-10-13VIDEO: MX5: Switch MX5 to CONFIG_VIDEOStefano Babic
The framebuffer driver for MX5 is based on CONFIG_LCD. In the current implementation, there is a serious bug because the required memory is allocated before relocation, but the driver knows only later which is the resolution of the display. The patch switches the driver to CONFIG_VIDEO and the memory is allocated by the driver itself. We also need to switch the vision2 board code and config file in the same commit so that this commit will be bisectable.
