This series of patches adds loadable kernel module and power management
support to Tegra PCIe host controller driver. irq_set_msi_desc() and
tegra_cpuidle_pcie_irqs_in_use() symbols will be taken care in next
set of patches.
These patches are tested on Jetson TK1, TX1 and TX2 platforms, following
are the verification details.
- Multiple module insert & remove
- PCIe device functionality after module insert
- Free clock, resets, regulators, powergate, iomem and interrupt
resources after module remove
- PCIe device functionality after resume from RAM
V2: PM QoS fix is dropped in V2 from this series because the fix is
incorporated in latest 'commit 0759e80b84e3 ("PM / QoS: Fix device resume
latency framework")'. Update commit message of few patches in V2.
V3: Patches to export irq_set_msi_desc() and tegra_cpuidle_pcie_irqs_in_use()
are dropped based on review comments. These symbols will be addressed in next
series. Took care of few other review comments.
V4: Dropped pci_find_host_bridge() export patch and added new patch to use
bus->sysdata for private data.
V5: Decouple from https://patchwork.ozlabs.org/patch/832053/ and rebase
on top of linux-next
