* clocksource: pass clocksource to read() callbackMagnus Damm2009-04-211-2/+2
| | | | | | | | | | | | | | Pass clocksource pointer to the read() callback for clocksources. This allows us to share the callback between multiple instances.

* [ARM] pass reboot command line to arch_reset()Russell King2009-03-191-1/+1
| | | | | | | | | | | | | | | OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

| * cpumask: convert struct clock_event_device to cpumask pointers.Rusty Russell2008-12-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Impact: change calling convention of existing clock_event APIs struct clock_event_timer's cpumask field gets changed to take pointer, as does the ->broadcast function.

* | [ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre2008-11-281-4/+0
|/ | | | | | | | | | | | | | | | Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.

* [ARM] msm: rename ARCH_MSM7X00A to ARCH_MSMBrian Swetland2008-10-221-11/+6
| | | | | | | | | | | The MSM architecture covers a wider family of chips than just the MSM7X00A. Move to a more generic name, in perparation for supporting the specific SoC variants as sub-architectures (ARCH_MSM7X01A, ARCH_MSM722X, etc). This gives us ARCH_MSM for the (many) common peripherals. This also removes the unused/obsolete config item MSM7X00A_IDLE. Signed-off-by: Brian Swetland <swetland@google.com>
