SPDX: Convert all of our single license tags to Linux Kernel style 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: Add support for the ANX9804 parallel lcd to dp bridge chip Add support for the ANX9804 bridge chip, which can take pixel data coming from a parallel LCD interface and translate it on the fly into a DP interface for driving eDP TFT displays. It uses I2C for configuration. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Anatolij Gustschin <agust@denx.de>

sunxi: video: Convert panel I2C to use DM_I2C Two displays supported by the sunxi display driver (each one used by a single board) require initialization over I2C. Both previously used i2c_soft; replace this with the i2c-gpio instance that already exists in those boards' device trees (sun5i-a13-utoo-p66 and sun6i-a31-colombus). Since the i2c-gpio nodes are not referenced by any other node in the device trees (the device trees have no panel node), the I2C bus is selected by its node name. This panel initialization code was the only i2c_soft user, so the i2c_soft GPIO setup code can be removed now as well.
