2010-05-26driver core: add devname module aliases to allow module on-demand auto-loadingKay Sievers2-2/+3
This adds: alias: devname:<name> to some common kernel modules, which will allow the on-demand loading of the kernel module when the device node is accessed. Ideally all these modules would be compiled-in, but distros seems too much in love with their modularization that we need to cover the common cases with this new facility. It will allow us to remove a bunch of pretty useless init scripts and modprobes from init scripts. The static device node aliases will be carried in the module itself. The program depmod will extract this information to a file in the module directory: $ cat /lib/modules/2.6.34-00650-g537b60d-dirty/modules.devname # Device nodes to trigger on-demand module loading. microcode cpu/microcode c10:184 fuse fuse c10:229 ppp_generic ppp c108:0 tun net/tun c10:200 dm_mod mapper/control c10:235 Udev will pick up the depmod created file on startup and create all the static device nodes which the kernel modules specify, so that these modules get automatically loaded when the device node is accessed: $ /sbin/udevd --debug ... static_dev_create_from_modules: mknod '/dev/cpu/microcode' c10:184 static_dev_create_from_modules: mknod '/dev/fuse' c10:229 static_dev_create_from_modules: mknod '/dev/ppp' c108:0 static_dev_create_from_modules: mknod '/dev/net/tun' c10:200 static_dev_create_from_modules: mknod '/dev/mapper/control' c10:235 udev_rules_apply_static_dev_perms: chmod '/dev/net/tun' 0666 udev_rules_apply_static_dev_perms: chmod '/dev/fuse' 0666 A few device nodes are switched to statically allocated numbers, to allow the static nodes to work. This might also useful for systems which still run a plain static /dev, which is completely unsafe to use with any dynamic minor numbers. Note: The devname aliases must be limited to the *common* and *single*instance* device nodes, like the misc devices, and never be used for conceptually limited systems like the loop devices, which should rather get fixed properly and get a control node for losetup to talk to, instead of creating a random number of device nodes in advance, regardless if they are ever used. This facility is to hide the mess distros are creating with too modualized kernels, and just to hide that these modules are not compiled-in, and not to paper-over broken concepts.

2010-05-25fb_defio: fix for non-dirty ptesAlbert Herranz1-8/+32
Fix a problem observed while using fb_defio with a short delay on a PowerPC platform. It is possible that page_mkclean() is invoked in the deferred io work function _before_ a PTE has been marked dirty. In this case, the page is removed from the defio pagelist but page_mkclean() does not write-protect the page again. The end result is that defio ignores all subsequent writes to the page and the corresponding portions of the framebuffer never get updated. The fix consists in keeping track of the pages with non-dirty PTEs, re-checking them again on the next deferred io work iteration. Note that those pages are not passed to the defio callback as they are not written by userspace yet.

This work includes the following: - Implement handler for FBIO_WAITFORVSYNC ioctl. - Allocate the data and palette buffers separately. A consequence of this is that the palette and data loading is now done in different phases. And that the LCD must be disabled temporarily after the palette is loaded but this will only happen once after init and each time the palette is changed. I think this is OK. - Allocate two (ping and pong) framebuffers from memory. - Add pan_display handler which toggles the LCDC DMA registers between the ping and pong buffers.

Now that the WM831x core uses genirq for the IRQ controller there is no need to use the WM831x-specific wrappers to request interrupts so convert to use genirq directly. Also use more meaningful strings to make /proc/interrupts more readily legible.

2010-05-25rtc-cmos: do dev_set_drvdata() earlier in the initializationDan Carpenter1-2/+3
The bug is an oops when dev_get_drvdata() returned null in cmos_update_irq_enable(). The call tree looks like this: rtc_dev_ioctl() => rtc_update_irq_enable() => cmos_update_irq_enable() It's caused by a race condition in the module initialization. It is rtc_device_register() which makes the ioctl operations live so I moved the call to dev_set_drvdata() before the call to rtc_device_register().

2010-05-25rtc-ds1302: add some abstraction for new platform supportMarc Zyngier1-18/+67
The current ds1302 driver (or at least the one that lives in /drivers/rtc) seems to be designed for memory mapped devices only. This make it quite hard to add support for GPIO-based implementations (as this is the case for the upcoming Arcom Vulcan). This patch moves the direct register access to inline functions with explicit names. Still not as good as a proper platform driver, but at least neater.

2010-05-25lis3: interrupt handlers for 8bit wakeup and click eventsSamu Onkalo2-13/+86
Content for the 8bit device threaded interrupt handlers. Depending on the interrupt line and chip configuration, either click or wakeup / freefall handler is called. In case of click, BTN_ event is sent via input device. In case of wakeup or freefall, input device ABS_ events are updated immediatelly. It is still possible to configure interrupt line 1 for fast freefall detection and use the second line either for click or threshold based interrupts. Or both lines can be used for click / threshold interrupts. Polled input device can be set to stopped state and still get coordinate updates via input device using interrupt based method. Polled mode and interrupt mode can also be used parallel. BTN_ events are remapped based on existing axis remapping information.

2010-05-25lis3: introduce platform data for second ff / wu unitSamu Onkalo1-2/+13
8 bit device has two wakeup / free fall units. It was not possible to configure the second unit. This patch introduces configuration entry to the platform data and also corresponding changes to the 8 bit setup function. High pass filters were enabled by default. Patch introduces configuration option for high pass filter cut off frequency and also possibility to disable or enable the filter via platform data. Since the control is a new one and default state was filter enabled, new option is used to disable the filter. This way old platform data is still compatible with the change.
