* cgroupfs: create /sys/fs/cgroup to mount cgroupfs onGreg KH2010-08-051-1/+12
| | | | | | | | | | | | | | | | | We really shouldn't be asking userspace to create new root filesystems. So follow along with all of the other in-kernel filesystems, and provide a mount point in sysfs. For cgroupfs, this should be in /sys/fs/cgroup/ This change provides that mount point when the cgroup filesystem is registered in the kernel.

* Driver core: Add BUS_NOTIFY_BIND_DRIVERMagnus Damm2010-08-052-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add BUS_NOTIFY_BIND_DRIVER as a bus notifier event. For driver binding/unbinding we with this in place have the following bus notifier events: - BUS_NOTIFY_BIND_DRIVER - before ->probe() - BUS_NOTIFY_BOUND_DRIVER - after ->probe() - BUS_NOTIFY_UNBIND_DRIVER - before ->remove() - BUS_NOTIFY_UNBOUND_DRIVER - after ->remove() The event BUS_NOTIFY_BIND_DRIVER allows bus code to be notified that ->probe() is about to be called. Useful for bus code that needs to setup hardware before the driver gets to run. With this in place platform drivers can be loaded and unloaded as modules and the new BIND event allows bus code to control for instance device clocks that must be enabled before the driver can be executed. Without this patch there is no way for the bus code to get notified that a modular driver is about to be probed.

| | | | | | | | | | | | | | debugfs no longer uses 'kernel_subsys' (which is gone), and other kernel/ksysfs.c code is always built, so DEBUG_FS does not need to depend on SYSFS.

* Driver core: Drop __must_check from bus_for_each_drv()Jean Delvare2010-08-051-3/+2
| | | | | | | | | | | | | | | | | | There is little rationale for marking bus_for_each_drv() __must_check. It is more of an iteration helper than a real function. You don't know in advance which callback it will be used on, so you have no clue how important it can be to check the returned value. In practice, this helper function can be used for best-effort tasks. As a matter of fact, bus_for_each_dev() is not marked __must_check. So remove it from bus_for_each_drv() as well. This is the same that was done back in October 2006 by Russell King for device_for_each_child(), for exactly the same reasons.

| | | | | | | | | | | | | | | | The kernel/hotplug sysctl variable (/proc/sys/kernel/hotplug file) was made conditional on CONFIG_NET by commit f743ca5e10f4145e0b3e6d11b9b46171e16af7ce (applied in 2.6.18) to fix problems with undefined references in 2.6.16 when CONFIG_HOTPLUG=y && !CONFIG_NET, but this restriction is no longer needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce basic support for the Freescale P1022DS reference board, based on the Freescale BSP for this board. This patch excludes the DIU, SSI, and MMC/SD drivers. Only a 36-bit DTS is provided. Update mpc86xx_smp_defconfig and mpc85xx_defconfig to support the P1022DS. This means enabling 64-bit physical address support, increasing the maximum zone order to 12 (to allow the DIU driver to allocate large chunks), and clean up the audio options to disable the deprecated OSS support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | P1021 processors have no dedicated ROM to store the QE microcode, so the fimrware is stored externally, and it is U-Boot responsibility to load it. It might be that the board is booting without QE, e.g. currently U-Boot doesn't support QE for P1021MDS boards, which means that QE isn't initialized, and so the board hangs early at boot. This patch fixes the issue by marking QE as disabled and checking the state in the probing code. U-Boot should fixup the state if it initialized the QE.

The sequence is sent 9 times which seems to be necessary if a slave "misses" more than one clock cycle. For 400 kHz bus speed, the fixup is also ~70us (81us vs. 150us) faster. Tested on a custom Lite5200b derived board, with a Dallas RTC, AD sensors and NXP IO expander chips attached to the i2c. Changes vs. v1: - use improved bus fixup sequence for all chips (not only the 5200) - calculate real clock from defaults if no clock is given in the device tree - better description (I hope) of the changes. I didn't split the changes in this file into three parts as recommended by Grant, as they actually belong together (i.e. they address one single problem, just in three places of one single source file).

| | * powerpc/5121: fsl-diu-fb: fix issue with re-enabling DIU area descriptorAnatolij Gustschin2010-08-011-15/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On MPC5121e Rev 2.0 re-configuring the DIU area descriptor by writing new descriptor address doesn't always work. As a result, DIU continues to display using old area descriptor even if the new one has been written to the descriptor register of the plane. Add the code from Freescale MPC5121EADS BSP for writing descriptor addresses properly. This fixes the problem for Rev 2.0 silicon.
