2013-05-25drivers/video: implement a simple framebuffer driverStephen Warren1-0/+17
A simple frame-buffer describes a raw memory region that may be rendered to, with the assumption that the display hardware has already been set up to scan out from that buffer. This is useful in cases where a bootloader exists and has set up the display hardware, but a Linux driver doesn't yet exist for the display hardware. Examples use-cases include: * The built-in LCD panels on the Samsung ARM chromebook, and Tegra devices, and likely many other ARM or embedded systems. These cannot yet be supported using a full graphics driver, since the panel control should be provided by the CDF (Common Display Framework), which has been stuck in design/review for quite some time. One could support these panels using custom SoC-specific code, but there is a desire to use common infra-structure rather than having each SoC vendor invent their own code, hence the desire to wait for CDF. * Hardware for which a full graphics driver is not yet available, and the path to obtain one upstream isn't yet clear. For example, the Raspberry Pi. * Any hardware in early stages of upstreaming, before a full graphics driver has been tackled. This driver can provide a graphical boot console (even full X support) much earlier in the upstreaming process, thus making new SoC or board support more generally useful earlier.

2013-04-04video: fb: vt8500: Convert framebuffer drivers to standardized bindingTony Prisk1-0/+6
Now that a display timing binding is available, convert our almost identical binding to use the standard binding. This patch converts the vt8500 and wm8505 framebuffer drivers and associated dts/dtsi files to use the standard binding as defined in bindings/video/display-timing.txt. There are two side-effects of making this conversion: 1) The fb node should now be in the board file, rather than the soc file as the display-timing node is a child of the fb node. 2) We still require a bits per pixel property to initialize the framebuffer for the different lcd panels. Rather than including this as part of the display timing, it is moved into the framebuffer node. I have also taken the opportunity to alphabetise the includes of each driver to avoid double-ups.

2013-03-12videomode: simplify videomode Kconfig and MakefileTomi Valkeinen1-20/+2
This patch simplifies videomode related Kconfig and Makefile. After this patch, there's only one non-user selectable Kconfig option left, VIDEOMODE_HELPERS. The reasons for the change: * Videomode helper functions are not something that should be shown in the kernel configuration options. The related code should just be included if it's needed, i.e. selected by drivers using videomode. * There's no need to have separate Kconfig options for videomode and display_timing. First of all, the amount of code for both is quite small. Second, videomode depends on display_timing, and display_timing in itself is not really useful, so both would be included in any case. * CONFIG_VIDEOMODE is a bit vague name, and CONFIG_VIDEOMODE_HELPERS describes better what's included.

Major parts of this interface are: a) Path: path is a output device connected to a panel or HDMI TV. Main operations of the path is set/get timing/output color. fb operates output device through path structure. b) Ovly: Ovly is a buffer shown on the path. Ovly describes frame buffer and its source/destination size, offset, input color, buffer address, z-order, and so on. Each fb device maps to one overlay. 3. hw folder contains implementation of hardware operations defined by core.c. It registers paths for fb use. 4. panel folder contains implementation of panels. It's connected to path. Panel drivers would also regiester panels and linked to path when probe.

All children are read into an array, that can be queried. If no native mode is specified, the first subnode will be used.

2013-01-24video: add display_timing and videomodeSteffen Trumtrar1-0/+6
Add display_timing structure and the according helper functions. This allows the description of a display via its supported timing parameters. Also, add helper functions to convert from display timings to a generic videomode structure. The struct display_timing specifies all needed parameters to describe the signal properties of a display in one mode. This includes - ranges for signals that may have min-, max- and typical values - single integers for signals that can be on, off or are ignored - booleans for signals that are either on or off As a display may support multiple modes like this, a struct display_timings is added, that holds all given struct display_timing pointers and declares the native mode of the display. Although a display may state that a signal can be in a range, it is driven with fixed values that indicate a videomode. Therefore graphic drivers don't need all the information of struct display_timing, but would generate a videomode from the given set of supported signal timings and work with that. The video subsystems all define their own structs that describe a mode and work with that (e.g. fb_videomode or drm_display_mode). To slowly replace all those various structures and allow code reuse across those subsystems, add struct videomode as a generic description. This patch only includes the most basic fields in struct videomode. All missing fields that are needed to have a really generic video mode description can be added at a later stage.

I'm reviving an old patch from 2009 that adds support for GXT4000P and GXT6500P adapter to the gxt4500 driver. See threads at http://marc.info/?l=linux-fbdev-devel&m=124345080216952&w=2 and https://lists.ozlabs.org/pipermail/linuxppc-dev/2009-June/072672.html for more details. This patch adds support for GXT4000P and GXT6500P cards found on some IBM pSeries machines. GXT4000P/6000P and GXT4500P/6500P couples are identical from software's point of view and are based on the same Raster Engine (RC1000), except for a different reference clock for the PLL. GXT6x00P models are equipped with an additional Geometry Engine (GT1000) but this driver doesn't use it.

This requires defining FB_CFB_REV_PIXELS_IN_BYTE and additionally setting var.nonstd to the value FB_NONSTD_REV_PIX_IN_B. Note that it is not enough to set da8xx_fb_var.nonstd to this value statically, since FBIOPUT_VSCREENINFO ioctl might pass var struct with .nonstd field set to zero or another value.
