Move individual start address setting to viafb_set_primary_address and viafb_set_secondary_address and make it more flexible to reuse it for panning. Using central functions makes it easier to follow HW manipulations. Remove crt locking as it should be only needed for timing manipulation. Move iga_path manipulation to via_pci_probe. Remove memset for screen cleaning as it is currently done only for the second screen. This is not needed for normal operation but has a little chance of causing unwanted display artifacts. This can be fixed later more consistent and more efficient (using viafb_fillrect) if needed. This is a code clenup, no notable runtime changes expected. Signed-off-by:

Shrink and merge viafb_update_viafb_par. This removes a lot of duplicated data in viafb_par. Use the relevant data of fb_info instead. On the way it removes an inconsistency in handling a second framebuffer which only worked because viafbinfo1->par is modified to point to the same viafb_par as viafbinfo->par. Code cleanup only, no runtime change expected. Signed-off-by:

Currently the start address is set to an initial value every time viafb_setmode is called. This is not done consistently along graphic cores and not even the whole address but often only parts of it. On top of that it seems useless as the real/final address will be set by viafb_set_start_addr a few lines later. Remove this superfluous initalization to shrink register initalization and as a start to decouple primary and secondary display. Code cleanup, no notable runtime change expected. Signed-off-by:

The current code initializes the register for CX700 chips 2 times due to a missing break as discovered by Harald Welte. As CX700 and VX800 have exactly the same register initialization we can use one for both to avoid duplicated code. As this is a pure code cleanup no measurable runtime effects are expected.

Add LCD controller (LCDC) driver for TI's DA8xx/OMAP-L1xx architecture. LCDC specifications can be found at http://www.ti.com/litv/pdf/sprufm0a. LCDC on DA8xx consists of two independent controllers, the Raster Controller and the LCD Interface Display Driver (LIDD) controller. LIDD further supports character and graphic displays. This patch adds support for the graphic display (Sharp LQ035Q3DG01) found on the DA830 based EVM. The EVM details can be found at: http://support.spectrumdigital.com/boards/dskda830/revc/.

Add a framebuffer driver for Qualcomm MSM/QSD SoCs, tested on HTC Dream smartphone (aka T-Mobile G1, aka ADP1). Brian said: I did the original quick and dirty version for bringup. Rebecca took over and (re)wrote the bulk of the driver, getting things stable for production ship of Dream and Sapphire, and Dima is currently adding support for later Qualcomm chipsets (QSD8x50, etc).

Previously, the only external (to dispc.c) IRQ handler was RFBI's frame done handler. dispc's IRQ framework was very dumb: you could only have one handler, and the semantics of {request,free}_irq were odd, to say the least. The new framework allows multiple consumers to register arbitrary IRQ masks. Signed-off-by:Daniel Stone <daniel.stone@nokia.com> Signed-off-by:

Leaving interface clocks enabled causes dss pwrdm to stay in active state when mpu is in active state. This fix puts dss to sleep state when it is not needed. Earlier version broke framebuffer on 24xx. This is fixed by enabling clocks before trying to access DISPC_IRQSTATUS register. Signed-off-by:

The LCD controller (EPSON S1D13744) supports rotation (0, 90, 180 and 270 degrees) on hardware just setting the bits 0 and 1 of 0x28 register (LCD Panel Configuration Register). Now it is possible to use this caps only setting the angle degree on var rotate of fb_var_screeninfo using the FBIOPUT_VSCREENINFO ioctl. Fixed-by:

Add glue to control the OMAP_LDP LCD as a frame buffer device using the existing dispc.c driver under omapfb. Patch updated for mainline kernel. Note that the drivers/video/omap should be updated to pass omap_lcd_config in platform_data. The patch should also be updated to compile if twl4030 is not selected, and eventually to use the regulator framework. Fixed-by:

The 3430SDP uses the same panel as the 2430SDP. The main difference are in the GPIO lines used for panel enable and backlight, and the VAUX register/commands sent to the TWL4030 power subsystem. Also, some misc. whitespace cleanups. Fixed-by:

Many gpio chips allow to generate interrupts when the value of a pin changes. This patch gives usermode application the opportunity to make use of this feature by calling poll(2) on the /sys/class/gpio/gpioN/value sysfs file. The edge to trigger can be set in the edge file in the same directory. Possible values are "none", "rising", "falling", and "both". Using level triggers is not possible with current sysfs since nothing changes the GPIO value (and the IRQ keeps triggering). Edge triggering will "just work". Note that if there was an event between read() and poll(), the poll() returns immediately. Also note that this version only supports true GPIO interrupts. Some later patch might be able to synthesize this behavior by timer-driven polling; some systems seem to need that.

The Langwell chip is the IO hub for Intel Moorestown platform which has a 64-pin gpio block device inside. It is exposed as a dedicated PCI device. We use it to control outside peripheral as well as to do IRQ demuxing. The gpio block uses MSI to send level type interrupt to IOAPIC. Signed-off-by:
