sunxi: video: HDMI: Fix clock setup

2019-03-28T22:45:41Z

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. Fixes: 56009451d843 ("sunxi: video: Add A64/H3/H5 HDMI driver") Signed-off-by: Jernej Skrabec Acked-by: Maxime Ripard

sunxi: display: Implement fallback to ddc probe when hpd fails

2019-02-15T15:30:44Z

There are HDMI displays where hpd pin is not connected, thus we cannot get it to work unless we specifically set the resolution. Rework the display probing, so hotplug detect failure causes fallback to probing ddc for EDID data. Signed-off-by: Priit Laes

sunxi: display: Move DDC PLL setup to HDMI init

Move PLL initialization code to single place so we won't call it every time we query for EDID data. Signed-off-by: Priit Laes

sunxi: use 6MHz PLL_VIDEO step for DE2 for higher resolution LCD

2018-11-13T16:47:06Z

DE2 SoCs can support LCDs up to 1080p (e.g. A64), and 3MHz step won't let PLL_VIDEO be high enough for them. Use 6MHz step for PLL_VIDEO when using DE2, to satisfy 1080p LCD.

video: sunxi: de2: fix SimpleFB node creation when DE2 not probed

2018-07-31T06:09:47Z

Sometimes when a monitor without EDID information is plugged, the DE2 won't be probed (because of lack of timing information), but the HDMI node is probed, thus a SimpleFB node with invalid information will be populated. Also detect whether DE2 is probed when creating SimpleFB node.

If compile with support for the efi loader we need to mark the pages allocated for the framebuffer as reserved so the kernel won't attempt to use them for other uses. Signed-off-by: Emmanuel Vadot Acked-by: Heinrich Schuchardt Signed-off-by: Alexander Graf

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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

sunxi: video: mark framebuffer as EFI reserved memory

2018-03-09T17:24:49Z

Inform the EFI subsystem that the framebuffer memory is reserved. Without the patch the AllocatePool boot service allocates memory from the framebuffer which will will be overwritten by screen output. Signed-off-by: Heinrich Schuchardt
