2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-12-13dm: treewide: Rename ..._platdata variables to just ..._platSimon Glass
Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-05-18common: Drop net.h from common headerSimon Glass
Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-12-02common: Move board_get_usable_ram_top() out of common.hSimon Glass
Move this function into init.h which seems to be designed for this sort of thing. Also update the header to declare struct global_data so that it can be included without global_data.h being needed. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2019-07-29video: fsl_dcu_fb: add DM_VIDEO supportIgor Opaniuk
Extend the driver to build with DM_VIDEO enabled. DTS files must additionally include 'u-boot,dm-pre-reloc' property in soc and child nodes to enable driver binding to fsl_dcu_fb device. Currently display timings aren't obtained from DT. Signed-off-by: Igor Opaniuk <igor.opaniuk@toradex.com> Reviewed-by: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>
2019-07-29video: fsl_dcu_fb: refactor init functionsIgor Opaniuk
Move dcu-related code to fsl_dcu_probe_common, keep in video_hw_init() only legacy video stack (filling GraphicPanel struct etc.). Add wrappers for all init functions, that will let to provide struct fb_info as an additional param (needed for further moving it from the global scope to driver private data struct in DM converted driver).

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-04-14video: fsl_dcu_fb: Enable pixel clock after initializationStefan Agner
When enabling the DCU and pixel clock, the test mode is activated since this is the reset configuration. The test mode immediately shows a red screen on a LCD. A moment later, the DCU gets initialized properly. This patch enables the pixel clock after initialization of the DCU control register. This avoids this initial flicker on LCD screens. While at it change the polarity of pixel clock to display samples data on the rising edge.

2017-04-14video: fsl_dcu_fb: fix framebuffer to the end of memoryStefan Agner
Fix the framebuffer location to the very end of the available memory. This allows to remove the area from available memory for the kernel, which in turn allows to display the splash screen through the Linux kernel boot process. Ideas has been taken from the sunxi display driver, e.g. 20779ec3a5 ("sunxi: video: Dynamically reserve framebuffer memory") Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Signed-off-by: Sanchayan Maity <maitysanchayan@gmail.com>
