2020-05-17efi_loader: round the memory area in efi_add_memory_map()Michael Walle
Virtually all callers of this function do the rounding on their own. Some do it right, some don't. Instead of doing this in each caller, do the rounding in efi_add_memory_map(). Change the size parameter to bytes instead of pages and remove aligning and size calculation in all callers. There is no more need to make the original efi_add_memory_map() (which takes pages as size) available outside the module. Thus rename it to efi_add_memory_map_pg() and make it static to prevent further misuse outside the module. Signed-off-by: Michael Walle <michael@walle.cc> Add missing comma in sunxi_display.c.

2019-09-21sunxi: video: HDMI: Fix LCD clock dividerMark Kettenis
Currently we may end up with an LCD clock divider that differs from the HDMI PHY clock divider if we can't exactly match the pixel clock. Fix this by using DIV_ROUND_UP to calculate the divider. This works since the PLL is chosen such that the resulting pixel clock is never higher than the requested pixel clock.

2019-03-28sunxi: video: HDMI: Fix clock setupJernej Skrabec
Currently, HDMI driver doesn't consider minimum and maximum allowed rate of pll3 (video PLL). It works most of the time, but not always. Consider monitor with resolution 1920x1200, which has pixel clock rate of 154 MHz. Current code would determine that pll3 rate has to be set to 154 MHz. However, minimum supported rate is 192 MHz. In this case video output just won't work. The reason why the driver is written in the way it is, is that at the time HDMI PHY and clock configuration wasn't fully understood. But now we have needed knowledge, so the issue can be fixed. With this fix, clock configuration routine uses full range (1-16) for clock divider instead of limited one (1, 2, 4, 11). It also considers minimum and maximum allowed rate for pll3.

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>

Video driver for older Allwinner SoCs uses cfb console framework which in turn uses struct ctfb_res_modes to hold timing informations. However, DM video framework uses different structure - struct display_timing.
