* powerpc/83xx: Use sizeof correct type when ioremappingDan Carpenter2017-08-311-2/+2
| | | | | | | | | | | | | | | There is a cut and paste error here so we use sizeof(struct mpc83xx_pmc) to remap the memory for "clock_regs". That sizeof() is 20 bytes and we only need to remap 12 bytes. It presumably doesn't affect run time too much... I changed them to both use sizeof(*variable_name) because that's the preferred kernel style these days.

* powerpc: Remove all usages of NO_IRQMichael Ellerman2016-09-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NO_IRQ has been == 0 on powerpc for just over ten years (since commit 0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change platforms to use it")). It's also 0 on most other arches. Although it's fairly harmless, every now and then it causes confusion when a driver is built on powerpc and another arch which doesn't define NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least some of which are to work around that problem. So we'd like to remove it. This is fairly trivial in the arch code, we just convert: if (irq == NO_IRQ) to if (!irq) if (irq != NO_IRQ) to if (irq) irq = NO_IRQ; to irq = 0; return NO_IRQ; to return 0; And a few other odd cases as well. At least for now we keep the #define NO_IRQ, because there is driver code that uses NO_IRQ and the fixes to remove those will go via other trees. Note we also change some occurrences in PPC sound drivers, drivers/ps3, and drivers/macintosh. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
* powerpc: don't use module_init in non-modular 83xx suspend codePaul Gortmaker2015-06-161-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | The suspend.o is built for SUSPEND -- which is bool, and hence this code is either present or absent. It will never be modular, so using module_init as an alias for __initcall can be somewhat misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering.

* powerpc: make of_device_ids constUwe Kleine-König2014-09-251-2/+2
| | | | | | | | | | | | | of_device_ids (i.e. compatible strings and the respective data) are not supposed to change at runtime. All functions working with of_device_ids provided by <linux/of.h> work with const of_device_ids. This allows to mark all struct of_device_id const, too. While touching these line also put the __init annotation at the right position where necessary.

* powerpc: Delete non-required instances of include <linux/init.h>Paul Gortmaker2014-01-151-1/+0
| | | | | | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. The one instance where we add an include for init.h covers off a case where that file was implicitly getting it from another header which itself didn't need it.

* drivercore: revert addition of of_match to struct deviceGrant Likely2011-05-181-2/+5
| | | | | | | | | | | | | | | Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

* of: Remove duplicate fields from of_platform_driverGrant Likely2010-05-221-2/+5
| | | | | | | | | | | | | | | | .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.

* powerpc/83xx/suspend: Clear deep_sleeping after devices resumeAnton Vorontsov2009-12-101-2/+2
| | | | | | | | | | | | | | | Currently 83xx PMC driver clears deep_sleeping variable very early, before devices are resumed. This makes fsl_deep_sleep() unusable in drivers' resume() callback. Sure, drivers can store fsl_deep_sleep() value on suspend and use the stored value on resume. But a better solution is to postpone clearing the deep_sleeping variable, i.e. move it into finish() callback.
