2018-11-13dm: video: bridge: don't fail to activate bridge if reset or sleep GPIO is ↵Vasily Khoruzhick
missing Both GPIOs are optional, so we shouldn't fail if any is missing. Without this fix reset is not deasserted if sleep GPIO is missing.

2018-05-10SPDX: Convert a few files that were missed beforeTom Rini
As part of the main conversion a few files were missed. These files had additional whitespace after the '*' and before the SPDX tag and my previous regex was too strict. This time I did a grep for all SPDX tags and then filtered out anything that matched the correct styles.

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>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>

This is a eDP bridge similar to ANX9804, it allows to connect eDP panels to the chips that can output only parallel signal Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com> [agust: fixed most checkpatch errors/warnings] Signed-off-by: Anatolij Gustschin <agust@denx.de>
2017-10-26dm: video: bridge: add operation to read EDIDVasily Khoruzhick
Add an operation to read EDID, since bridge may have ability to read EDID from the panel that is connected to it, for example LCD<->eDP bridge. Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com>
2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

For vidconsole_post_probe(), it is common coding style to let a probe method return the value of a register function. The others will become simple wrapper functions.

Some video bridges will not have GPIOs to control reset, etc. Allow these to be optional. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-08-05dm: video: Add support for the NXP PTN3460 bridgeSimon Glass
This chip provides an eDP to LVDS bridge which is useful for SoCs that don't support LVDS displays (or it would waste scarce pins). There is no setup required by this chip, other than to adjust power-down and reset pins, and those are managed by the uclass. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-08-05video: Work around lack of pinctrlSimon Glass
We haven't quite got pinctrl ready to apply to mainline. We don't want to GPIO pull-up/down support to the driver model GPIO layer either. So work around this for now. We can address this when pinctrl is complete. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-08-05dm: video: Add support for video bridgesSimon Glass
A video bridge typically converts video from one format to another, e.g. DisplayPort to LVDS. Add driver model support for these with a simple interface to control activation and backlight. The uclass supports GPIO control of power and reset lines. Signed-off-by: Simon Glass <sjg@chromium.org>
