Add accelerated bitblt functions to s1d13xxx based video chipsets, more specificly functions copyarea and fillrect. It has only been tested and activated for 13506 chipsets but is expected to work for the majority of s1d13xxx based chips. This patch also cleans up the driver with respect of whitespaces and other formatting issues. We update the current status comments. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

Use standard fields fbinfo.fix.smem_start and fbinfo.fix.smem_len for physical address and length of framebuffer. This also fixes output of the 'fbset -i' command - address and length of the framebuffer are displayed correctly. Signed-off-by:

With KMS we have ran into an issue where we really want the KMS fb driver to be the one running the console, so panics etc can be shown by switching out of X etc. However with vesafb/efifb built-in, we end up with those on fb0 and the KMS fb driver on fb1, driving the same piece of hw, so this adds an fb info flag to denote a firmware fbdev, and adds a new aperture base/size range which can be compared when the hw drivers are installed to see if there is a conflict with a firmware driver, and if there is the firmware driver is unregistered and the hw driver takes over. It uses new aperture_base/size members instead of comparing on the fix smem_start/length, as smem_start/length might for example only cover the first 1MB of the PCI aperture, and we could allocate the kms fb from 8MB into the aperture, thus they would never overlap.

When changing video timing dynamically via fbset the screen sporadically is rendered black. With the attached fix which disables VCO prior to timing register change the problem disappears. I had a look at the Xserver register setup code. Here the VCO is disabled in the same way [1]. This patch is taken from vga-sync-field version 0.0.11 [2][3].

The driver's fb_mmap function is essentially the same as a generic fb_mmap function. Delete driver's function and use the generic one. A difference is that generic function marks frame buffer memory as VM_IO | VM_RESERVED. The driver's function marks it as VM_IO only. Signed-off-by:

Add support for the ARGB1888 and ARGB4888 hardware to the Samsung SoC Framebuffer driver (s3c-fb.c). ARGB1888 and ARGB4888 is decided by var->transp.length and this variable is set by s3c_fb_check_var(). In s3c_fb_check_var(), if var->vits_per_pixel is 25 or 28, then var->transp.length would be 1 or 3. Therefore alpha mode(ARGB1888 or ARGB4888) could be decided through that variable. For using alpha mode, you need to set the following: This code should be added to your machine code as platform data. static struct s3c_fb_pd_win xxx_fb_win0 = { /* this is to ensure we use win0 */ .win_mode = { .pixclock = (8+8+8+240)*(38+4+38+400), .left_margin = 8, .right_margin = 8, .upper_margin = 38, .lower_margin = 38, .hsync_len = 8, .vsync_len = 4, .xres = 240, .yres = 400, }, .max_bpp = 32, .default_bpp = 24, }; static struct s3c_fb_pd_win xxx_fb_win1 = { .win_mode = { .pixclock = (8+8+8+240)*(38+4+38+400), .left_margin = 8, .right_margin = 8, .upper_margin = 38, .lower_margin = 38, .hsync_len = 8, .vsync_len = 4, .xres = 240, .yres = 400, }, .max_bpp = 32, .default_bpp = 28, }; static struct s3c_fb_platdata xxx_lcd_pdata __initdata = { .win[0] = &ncp_fb_win0, .win[1] = &ncp_fb_win1, .vidcon0 = VIDCON0_VIDOUT_RGB | VIDCON0_PNRMODE_RGB, .vidcon1 = VIDCON1_INV_HSYNC | VIDCON1_INV_VSYNC, .setup_gpio = xxx_fb_gpio_setup, }; s3c_fb_set_platdata(&xxx_lcd_pdata); The above code sets pixelformat for window0 layer to RGB888 and window1 layer to ARGB4888.

AFAICT the code which checks that the requested pixclock value is within bounds is incorrect. It ensures that the lcdc core clock is at least (bytes per pixel) times higher than the pixel clock rather than just greater than or equal to. There are tighter restrictions on the pixclock value as a function of bus width for STN panels but even then it isn't a simple relationship as currently checked for. IMO either something like the below patch should be applied or else more detailed checking logic should be implemented which takes in to account the panel type as well. Signed-off-by:

Now we have __initconst, we can finally move the external declarations for the various Linux logo structures to <linux/linux_logo.h>. James' ack dates back to the previous submission (way to long ago), when the logos were still __initdata, which caused failures on some platforms with some toolchain versions. Signed-off-by:

The LIS302DL accelerometer chip has a 'click' feature which can be used to detect sudden motion on any of the three axis. Configuration data is passed via spi platform_data and no action is taken if that's not specified, so it won't harm any existing platform. To make the configuration effective, the IRQ lines need to be set up appropriately. This patch also adds a way to do that from board support code. The DD_* definitions were factored out to an own enum because they are specific to LIS3LV02D devices. Signed-off-by:

After measurement on my laptop, it seems that turning off the device does not bring any energy saving (within 0.1W precision). So let's keep the device always on. It simplifies the code, and it avoids the problem of reading a wrong value sometimes just after turning the device on. Moreover, since commit ef2cfc79 had been too zealous, the device was actually never turned off anyway. This patch also restores the damages done by this commit concerning the initialisation/poweroff. Also do more clean up with the usage of the lis3_dev global variable. Signed-off-by:

Furthermore, notice that the initial checks: if (!node->rb_left) child = node->rb_right; else if (!node->rb_right) child = node->rb_left; else { ... } guarantee that old->rb_right is set in the final else branch, therefore we can omit checking that again.
