| * | | powerpc/watchdog: Make default timeout for Book-E watchdog a Kconfig optionTimur Tabi2010-10-142-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PowerPC Book-E watchdog driver (booke_wdt.c) defines a default timeout value in the code based on whether it's a Freescale Book-E part of not. Instead of having hard-coded values in the driver, make it a Kconfig option. As newer chips gets faster, the current default values become less appropriate, since the timeout sometimes occurs before the kernel finishes booting. Making the value a Kconfig option allows BSPs to configure a new value without requiring the wdt_period command-line parameter to be set.

Add a .release method for the PowerPC Book-E Watchdog driver, so that the watchdog is disabled when the driver is closed. Loosely based on original code from Jiang Yutang <b14898@freescale.com>.

The reason for this change is to unify the struct of_device definition amongst all the architectures. It also remvoes the .sysdata, .slot, .portid and .clock_freq properties because they aren't actually used by anything. A subsequent patch will replace struct of_device entirely with struct platform_device and the of_platform support code will share common routines with the platform bus (but the bus instances themselves can remain separate). This patch also adds 'struct resources *resource' and num_resources to match the fields defined in struct platform_device. After this change, 'struct platform_device' can be used as a drop-in replacement for 'struct of_platform'. This change is in preparation for merging the of_platform_bus_type with the platform_bus_type. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

* watchdog: update/improve/consolidate watchdog driverRandy Dunlap2010-05-252-2/+1
| | | | | | | | | | | | | Move the limited watchdog driver help from kernel-parameters.txt to Documentation/watchdog/watchdog-parameters.txt and add info to it for all watchdog drivers except the ones that have driver-specific files already. Correct minor comments and MODULE_PARM_DESC() text in 2 places. Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

* watchdog: fix several MODULE_PARM_DESC stringsRandy Dunlap2010-05-256-13/+19
| | | | | | | | | | | | | | | | Fix MODULE_PARM_DESC() strings in several watchdog drivers. Some are simple as add a parenthesis. Others are problems from __stringify() being used on a variable name instead of a macro name, so the variable name is produced in the string instead of its build-time value. In these cases, create a macro for the value so that the module param description string is useful. Only pc87413_wdt has been built (due to toolchains).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For more clearance what the functions actually do, usb_buffer_alloc() is renamed to usb_alloc_coherent() usb_buffer_free() is renamed to usb_free_coherent() They should only be used in code which really needs DMA coherency. All call sites have been changed accordingly, except for staging drivers.
