* sparc: convert to clocksource_register_hz/khzJohn Stultz2011-03-161-3/+1
| | | | | | | This converts the sparc clocksources to use clocksource_register_hz/khz Signed-off-by: John Stultz <johnstul@us.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* dt/sparc: Eliminate users of of_platform_{,un}register_driverGrant Likely2011-02-281-9/+9
| | | | | | | | | Get rid of old users of of_platform_driver in arch/sparc. Most of_platform_driver users can be converted to use the platform_bus directly. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
* sparc: remove references to of_device and to_of_deviceGrant Likely2010-07-241-3/+3
| | | | | | | | of_device is just a #define alias to platform_device. This patch replaces all references to it with platform_device. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S. Miller <davem@davemloft.net>
* of/platform: remove all of_bus_type and of_platform_bus_type referencesGrant Likely2010-07-241-3/+3
| | | | | | | | | | | | | | | Both of_bus_type and of_platform_bus_type are just #define aliases for the platform bus. This patch removes all references to them and switches to the of_register_platform_driver()/of_unregister_platform_driver() API for registering. Subsequent patches will convert each user of of_register_platform_driver() into plain platform_drivers without the of_platform_driver shim. At which point the of_register_platform_driver()/of_unregister_platform_driver() functions can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S. Miller <davem@davemloft.net>
* of: Remove duplicate fields from of_platform_driverGrant Likely2010-05-221-9/+12
| | | | | | | | | | | | | | | | .name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.

* of: Always use 'struct device.of_node' to get device node pointer.Grant Likely2010-05-181-3/+3
| | | | | | | | | | | | The following structure elements duplicate the information in 'struct device.of_node' and so are being eliminated. This patch makes all readers of these elements use device.of_node instead. (struct of_device *)->node (struct dev_archdata *)->prom_node (sparc) (struct dev_archdata *)->of_node (powerpc & microblaze) Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

* sparc64: Use a seperate counter for timer interrupts and NMI checks, like x86.David S. Miller2010-04-121-0/+1
| | | | | | | | | This keeps us from having to use kstat_irqs_cpu() from the NMI handler, the former of which is a profiled function. Instead we use a currently empty slot in the cpu_data Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix clock event multiplier printf format.David S. Miller2009-12-111-1/+1
| | | | | | | | | | | | | | | | | | | | The type got changed to u32, so %lx generated warnings (and thus build failure on sparc64) Stephen Rothwell fixed it like so: - printk("clockevent: mult[%lx] shift[%d]\n", + printk("clockevent: mult[%ux] shift[%d]\n", But that's not a valid transformation, we now get: clockevent: mult[51539607x] shift[32] in the logs. Fix it to use the correct plain "%x" instead. Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc64: Use unsigned long long for u64.Sam Ravnborg2009-01-061-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Andrew Morton wrote: People keep on doing printk("%llu", some_u64); testing it only on x86_64 and this generates a warning storm on powerpc, sparc64, etc. Because they use `long', not `long long'. Quite a few 64-bit architectures are using `long' for their s64/u64 types. We should convert them all to `long long'. Update types.h so we use unsigned long long for u64 and fix all warnings in sparc64 code. Tested with an allnoconfig, defconfig and allmodconfig builds. This patch introduces additional warnings in several drivers. These will be dealt with in separate patches.

* sparc,sparc64: unify kernel/Sam Ravnborg2008-12-041-0/+862
o Move all files from sparc64/kernel/ to sparc/kernel - rename as appropriate o Update sparc/Makefile to the changes o Update sparc/kernel/Makefile to include the sparc64 files NOTE: This commit changes link order on sparc64! Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.
