* powerpc/85xx: remove mostly pointless mpc85xx_qe_init()Rasmus Villemoes2019-11-171-23/+0
| | | | | | | | | | | Since commit 302c059f2e7b (QE: use subsys_initcall to init qe), mpc85xx_qe_init() has done nothing apart from possibly emitting a pr_err(). As part of reducing the amount of QE-related code in arch/powerpc/ (and eventually support QE on other architectures), remove this low-hanging fruit.

* powerpc: Remove all usages of NO_IRQMichael Ellerman2016-09-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/rcpm: add RCPM driverchenhui zhao2016-03-041-0/+3
| | | | | | | | | | | | | | There is a RCPM (Run Control/Power Management) in Freescale QorIQ series processors. The device performs tasks associated with device run control and power management. The driver implements some features: mask/unmask irq, enter/exit low power states, freeze time base, etc. Signed-off-by: Chenhui Zhao <chenhui.zhao@freescale.com> Signed-off-by: Tang Yuantian <Yuantian.Tang@freescale.com> [scottwood: remove __KERNEL__ ifdef] Signed-off-by: Scott Wood <oss@buserror.net>

* genirq: Remove irq argument from irq flow handlersThomas Gleixner2015-09-161-1/+1
| | | | | | | | | | | | | | Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help!

| | | | | | | | | | | | | 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.

* QE: split function mpc85xx_qe_init() into two functions.Zhao Qiang2014-03-191-0/+6
| | | | | | | | | | | | New QE doesn't have par_io, it doesn't need to init par_io for new QE. Split function mpc85xx_qe_init() into mpc85xx_qe_init() and mpc85xx_qe_par_io_init(). Call mpc85xx_qe_init() for both new and old while mpc85xx_qe_par_io_init() after mpc85xx_qe_init() for old.

* powerpc/fsl-pci: Unify pci/pcie initialization codeJia Hongtao2012-09-121-0/+10
| | | | | | | | | | | | | | | | We unified the Freescale pci/pcie initialization by changing the fsl_pci to a platform driver. In previous PCI code architecture the initialization routine is called at board_setup_arch stage. Now the initialization is done in probe function which is architectural better. Also It's convenient for adding PM support for PCI controller in later patch. Now we registered pci controllers as platform devices. So we combine two initialization code as one platform driver.

* powerpc/85xx: don't call of_platform_bus_probe() twiceTimur Tabi2012-04-191-0/+6
| | | | | | | | | | | | | | | | | | | | | Commit 46d026ac ("powerpc/85xx: consolidate of_platform_bus_probe calls") replaced platform-specific of_device_id tables with a single function that probes the most of the busses in 85xx device trees. If a specific platform needed additional busses probed, then it could call of_platform_bus_probe() again. Typically, the additional platform-specific busses are children of existing busses that have already been probed. of_platform_bus_probe() does not handle those child busses automatically. Unfortunately, this doesn't actually work. The second (platform-specific) call to of_platform_bus_probe() never finds any of the busses it's asked to find. To remedy this, the platform-specific of_device_id tables are eliminated, and their entries are merged into mpc85xx_common_ids[], so that all busses are probed at once.
