[PATCH v6 1/3] PM: wakeup: Add routine to help fetch wakeup source object.

Some user might want to go through all registered wakeup sources and doing things accordingly. For example, SoC PM driver might need to do HW programming to prevent powering down specific IP which wakeup source depending on. So add this API to help walk through all registered wakeup source objects

[PATCH v6 2/3] Documentation: dt: binding: fsl: Add 'little-endian' and update Chassis define

By default, QorIQ SoC's RCPM register block is Big Endian. But there are some exceptions, such as LS1088A and LS2088A, are Little Endian. So add this optional property to help identify them. Actually LS2021A and other Layerscapes won't totally follow Chassis 2.1, so separate them from powerpc SoC.

[PATCH v6 3/3] soc: fsl: add RCPM driver

The NXP's QorIQ Processors based on ARM Core have RCPM module (Run Control and Power Management), which performs system level tasks associated with power management such as wakeup source control. This driver depends on PM wakeup source framework which help to collect wake information. Signed-off-

[PATCH] platform/powernv: Avoid re-registration of imc debugfs directory

export_imc_mode_and_cmd() function which creates the debugfs interface for imc-mode and imc-command, is invoked when each nest pmu units is registered. When the first nest pmu unit is registered, export_imc_mode_and_cmd() creates 'imc' directory under `/debug/powerpc`. In the subsequent invocations

[PATCH 1/3] powerpc/sriov: Remove VF eeh_dev state when disabling SR-IOV

When disabling virtual functions on an SR-IOV adapter we currently do not correctly remove the EEH state for the now-dead virtual functions. When removing the pci_dn that was created for the VF when SR-IOV was enabled we free the corresponding eeh_dev without removing it from the child device list

[PATCH 2/3] powerpc/pcidn: Make VF pci_dn management CONFIG_PCI_IOV specific

The powerpc PCI code requires that a pci_dn structure exists for all devices in the system. This is fine for real devices since at boot a pci_dn is created for each PCI device in the DT and it's fine for hotplugged devices since the hotplug slot driver will manage the pci_dn's devices in hotplug sl

[PATCH 3/3] powerpc/pcidn: Warn when sriov pci_dn management is used incorrectly

These functions can only be used on a SR-IOV capable physical function and they're only called in pcibios_sriov_enable / disable. Make them emit a warning in the future if they're used incorrectly and remove the dead code that checks if the device is a VF. Signed-off-by: Oliver O'Halloran --- ar
