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.

There are two cases when a node, having 2 childs, is erased: 'normal case': the successor is not the right-hand-child of the node to be erased 'special case': the successor is the right-hand child of the node to be erased Here some ascii-art, with following symbols (referring to the code): O: node to be deleted N: the successor of O P: parent of N C: child of N L: some other node normal case: O N / \ / \ / \ / \ L \ L \ / \ P ----> / \ P / \ / \ / / N C \ / \ \ C / \ special case: O|P N / \ / \ / \ / \ L \ L \ / \ N ----> / C \ / \ \ C / \ Notice that for the special case we don't have to reconnect C to N.

There is a call to write_lock() in gen_pool_destroy which is not balanced by any corresponding write_unlock(). This causes problems with preemption because the preemption-disable counter is incremented in the write_lock() call, but never decremented by any call to write_unlock(). This bug is gen_pool_destroy, and one of them is non-x86 arch-specific code. Signed-off-by:

The console blank timer is currently hardcoded to 10*60 seconds which might be annoying on systems with no input devices attached to wake up the console again. Especially during development, disabling the screen saver can be handy - for example when debugging the root fs mount mechanism or other scenarios where no userspace program could be started to do that at runtime from userspace. This patch defines a core_param for the variable in charge which allows users to entirely disable the blank feature at boot time by setting it 0. The value can still be overwritten at runtime using the standard ioctl call - this just allows to conditionally change the default. Signed-off-by:
