2023-08-02powerpc: Explicitly include correct DT includesRob Herring1-1/+1
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-03-16powerpc: Make generic_calibrate_decr() the defaultChristophe Leroy1-1/+0
ppc_md.calibrate_decr() is a mandatory item. Its nullity is never checked so it must be non null on all platforms. Most platforms define generic_calibrate_decr() as their ppc_md.calibrate_decr(). Have time_init() call generic_calibrate_decr() when ppc_md.calibrate_decr() is NULL, and remove default assignment from all machines.

Now that we've switched all the powerpc nommu and swiotlb methods to use the generic dma_direct_* calls we can remove these ops vectors entirely and rely on the common direct mapping bypass that avoids indirect function calls entirely. This also allows to remove a whole lot of boilerplate code related to setting up these operations.

2016-07-21powerpc: Move 32-bit probe() machine to later in the boot processBenjamin Herrenschmidt1-3/+1
This converts all the 32-bit platforms to use the expanded device-tree which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel didn't rely on platform initializations to setup the MMU since it sets it up entirely before probe_machine() so the move has comparatively less consequences though it's a bigger patch.

2014-03-20fsl/pci: The new pci suspend/resume implementationWang Dongsheng1-0/+1
If we do nothing in suspend/resume, some platform PCIe ip-block can't guarantee the link back to L0 state from sleep, then, when we read the EP device will hang. Only we send pme turnoff message in pci controller suspend, and send pme exit message in resume, the link state will be normal. When we send pme turnoff message in pci controller suspend, the links will into l2/l3 ready, then, host cannot communicate with ep device, but pci-driver will call back EP device to save them state. So we need to change platform_driver->suspend/resume to syscore->suspend/resume. So the new suspend/resume implementation, send pme turnoff message in suspend, and send pme exit message in resume. And add a PME handler, to response PME & message interrupt. Change platform_driver->suspend/resume to syscore->suspend/resume. pci-driver will call back EP device, to save EP state in pci_pm_suspend_noirq, so we need to keep the link, until pci_pm_suspend_noirq finish.

2012-09-12powerpc/fsl-pci: Unify pci/pcie initialization codeJia Hongtao1-33/+3
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.

2012-02-23powerpc/mpic: Remove duplicate MPIC_WANTS_RESET flagKyle Moffett1-3/+1
There are two separate flags controlling whether or not the MPIC is reset during initialization, which is completely unnecessary, and only one of them can be specified in the device tree. Also, most platforms in-tree right now do actually want to reset the MPIC during initialization anyways, which means lots of duplicate code passing the MPIC_WANTS_RESET flag. Fix all of the callers which currently do not pass the MPIC_WANTS_RESET flag to pass the MPIC_NO_RESET flag, then remove the MPIC_WANTS_RESET flag and make the code reset the MPIC by default.

2012-02-23powerpc/mpic: Remove MPIC_BROKEN_FRR_NIRQS and duplicate irq_countKyle Moffett1-1/+1
The mpic->irq_count variable is only used as a software error-checking limit to determine whether or not an IRQ number is valid. In board code which does not manually specify an IRQ count to mpic_alloc(), i.e. 0, it is automatically detected from the number of ISUs and the ISU size. In practice, all hardware ends up with irq_count == num_sources, so all of the runtime checks on mpic->irq_count should just check the value of mpic->num_sources instead. When platform hardware does not correctly report the number of IRQs, which only happens on the MPC85xx/MPC86xx, the MPIC_BROKEN_FRR_NIRQS flag is used to override the detected value of num_sources with the manual irq_count parameter. Since there's no need to manually specify the number of IRQs except in this case, the extra flag can be eliminated and the test changed to "irq_count != 0".

2011-12-07powerpc/mpic: Search for open-pic device-tree node if NULLKyle Moffett1-12/+1
Almost all PowerPC platforms use a standard "open-pic" device node so the mpic_alloc() function now accepts NULL for the device-node.

Instead of using the open-coded "reg" property lookup and address translation in mpic_alloc(), directly call of_address_to_resource(). This includes various workarounds for special cases which the naive of_address_translate() does not. Afterwards it is possible to remove the copiously copy-pasted calls to of_address_translate() from the 85xx/86xx/powermac platforms.

Currently it doesn't matter where the mdio nodes are placed, but with power management support (i.e. when sleep = <> properties will take effect), mdio nodes placement will become important: mdio controller is a part of the ethernet block, so the mdio nodes should be placed correctly. Otherwise we may wrongly assume that MDIO controllers are available during sleep.
