The remove member of the platform_driver bfin_t350mcqb_driver should use __devexit_p() to refer to the remove function, and that function should get __devexit markings. Likewise, the probe function should be marked with __devinit and not __init. Also, module_init() functions should be marked with __init rather than __devinit.

2009-06-17fbdev: add support for handoff from firmware to hw framebuffersDave Airlie4-2/+57
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.

2009-06-17Samsung SoC Framebuffer driver: add Alpha Channel supportInKi Dae1-3/+28
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.

2009-06-17atmel-lcdc: fix pixclock upper bound detectionBen Nizette1-1/+1
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.

2009-06-17lis3: add click functionDaniel Mack3-1/+39
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.

2009-06-17lis3: remove automatic shutdown of the deviceEric Piel3-71/+32
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 ef2cfc790bf5f0ff189b01eabc0f4feb5e8524df 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.

Add support for the TI VLYNQ high-speed, serial and packetized bus.

2009-06-17console: make blank timeout value a boot optionDaniel Mack1-6/+7
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.

Add EISA IDs for Network Peripherals FDDI boards. Descriptions taken from the respective EISA configuration files.

2009-06-17videobuf-dma-contig: zero copy USERPTR supportMagnus Damm1-5/+89
Since videobuf-dma-contig is designed to handle physically contiguous memory, this patch modifies the videobuf-dma-contig code to only accept a user space pointer to physically contiguous memory. For now only VM_PFNMAP vmas are supported, so forget hotplug. On SuperH Mobile we use this with our sh_mobile_ceu_camera driver together with various multimedia accelerator blocks that are exported to user space using UIO. The UIO kernel code exports physically contiguous memory to user space and lets the user space application mmap() this memory and pass a pointer using the USERPTR interface for V4L2 zero copy operation. With this approach we support zero copy capture, hardware scaling and various forms of hardware encoding and decoding.

valid Callers of alloc_pages_node() can optionally specify -1 as a node to mean "allocate from the current node". However, a number of the callers in fast paths know for a fact their node is valid. To avoid a comparison and branch, this patch adds alloc_pages_exact_node() that only checks the nid with VM_BUG_ON(). Callers that know their node is valid are then converted.

2009-06-17time: move PIT_TICK_RATE to linux/timex.hArnd Bergmann3-1/+3
PIT_TICK_RATE is currently defined in four architectures, but in three different places. While linux/timex.h is not the perfect place for it, it is still a reasonable replacement for those drivers that traditionally use asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency. Note that for Alpha, the actual value changed from 1193182UL to 1193180UL. This is unlikely to make a difference, and probably can only improve accuracy. There was a discussion on the correct value of CLOCK_TICK_RATE a few years ago, after which every existing instance was getting changed to 1193182. According to the specification, it should be 1193181.818181...

Changeset 1589a993f074124c3edfff03656e910bb472eeaa broke user visible names of flexcop-pci devices, as it did reorder the enum of card types, but did not adjust the array containing the card names. Reorder the names, and uses [FC_AIR_DVBT] = "Air2PC/AirStar 2 DVB-T" assignment style for more clarity. It also adds the revision Number to the name for SkyStar rev. 2.3 and rev 2.6 as I think it is useful to see in log output.
