| * rockchip: video: Add a display driver for rockchip LVDSJacob Chen2016-03-14-1/+255
| | | | | | | | | | | | | | | | Some Rockchip SoCs support LVDS output. Add a display driver for this so that these displays can be used on supported boards. Signed-off-by: Jacob Chen <jacob-chen@iotwrt.com> Acked-by: Simon Glass <sjg@chromium.org>
| * dm: video: Add a operation to display uclassJacob Chen2016-03-14-0/+3
| | | | | | | | | | | | | | | | | | The current display class only allow to get timing from edid. So add a operation to get timing directly from driver. In driver, I will use fdtdec_decode_display_timing to get timing. Signed-off-by: Jacob Chen <jacob-chen@iotwrt.com> Acked-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | Move this driver over to use driver model. This involves rearranging the code somewhat. The effect is that everything is run from the probe() method. Boards which use this are fixed up, but only seaboard is tested.

| | | | | | | | | | | At present we have code in arch/arm and code in drivers/video.

| | | | | | | | | | | | | | | | | | | | | | | | Boards with a saved environment may use 'lcd' in their stdout environment variable, expecting that this will enable output to the LCD. When the board moves to use driver model for video, this will no-longer work. Add a work-around to fix this. A warning messages is printed, and we will remove the work-around at the end of 2016.

| * video: bcm2835: use bus_to_phys() on FB addressStephen Warren2016-02-06-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FB address is generated by the firmware running on the GPU/VideoCore and is a "bus" address. This address is the other side of an IOMMU from the ARM upon which U-Boot is running. Use bus_to_phys() to convert this to an ARM physical address. Without this, U-Boot seems to work just fine, but once the Linux kernel boots on an RPi2, accessing the FB memory often causes a hard system hang.

| | | | | | | | | | | | Provide a way for the video console driver to be selected. This is controlled by the video driver's private data. This can be set up when the driver is probed so that it is ready for the video_post_probe() method. The font size is provided as well.

* video: Add a console driver that uses TrueType fontsSimon Glass2016-01-30-2/+580
| | | | | | | | | | | | | | | | | | | The existing 8x16 font is adequate for most purposes. It is small and fast. However for boot screens where information must be presented to the user, the console font is not ideal. Common requirements are larger and better-looking fonts. This console driver can use TrueType fonts built into U-Boot, and render them at any size. This can be used in scripts to place text as needed on the display. This driver is not really designed to operate with the command line. Much of U-Boot expects a fixed-width font. But to keep things working correctly, rudimentary support for the console is provided. The main missing feature is support for command-line editing. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Anatolij Gustschin <agust@denx.de>

* video: Provide a left margin for the text consoleSimon Glass2016-01-30-3/+3
| | | | | | | Allow the left margin to be set so that text does not have to be right up against the left side. On some panels this makes it hard to read. Signed-off-by: Simon Glass <sjg@chromium.org>

* video: Use fractional units for X coordinatesSimon Glass2016-01-30-42/+104
| | | | | | | | | | | | | | With anti-aliased fonts we need a more fine-grained horizontal position than a single pixel. Characters can be positioned to start part-way through a pixel, with anti-aliasing (greyscale edges) taking care of the visual effect. To cope with this, use fractional units (1/256 pixel) for horizontal positions in the text console.

| | | | | | | | | | | | This is a header file which provides a fairly light-weight TrueType rendering implementation. It is pulled from http://nothings.org/. The code style does not comply with U-Boot but I think it is best to leave alone to permit the source to be synced later if needed. The only change is to fix a reference to fabs() which should route through a macro to allow U-Boot to provide its own version. Signed-off-by: Simon Glass <sjg@chromium.org>

* rockchip: video: Add a display driver for rockchip HDMISimon Glass2016-01-21-0/+952
| | | | | | | | | | | | Some Rockchip SoCs support HDMI output. Add a display driver for this so that these displays can be used on supported boards. Unfortunately this driver is not fully functional. It cannot reliably read EDID information over HDMI. This seems to be due to the clocks being incorrect - the I2C bus speed appears to be up to 100x slower than the clock settings indicate. The root cause may be in the clock logic.

| | | | | | | | | | | | | | The current DisplayPort uclass is too specific. The operations it provides are shared with other types of output devices, such as HDMI and LVDS LCD displays. Generalise the uclass so that it can be used with these devices as well. Adjust the uclass to handle the EDID reading and conversion to display_timing internally.
