[PATCH v2 0/3] PCI: introduce TC9564 misc driver

[Alex Elder]

The Toshiba TC9564 is specialized SoC that implements a PCIe switch as
well as an Ethernet AVB/TSN bridge.  It also implements other functions,
including a reset and clock controller, an address translation unit, and
a few other devices.  PCIe BARs provide access to registers that manage
these IP blocks, and the SoC is modeled using a PCI endpoint bus in
devicetree.  This allows the IP blocks to be bound to platform drivers
using MMIO through the PCI BARs.

This series introduces the simple PCI driver necessary to implement the
PCI endpoint bus.  It enables the device, enables master access, and
then scans the devicetree subnodes to discover any devices defined
within the endpoint buses.

The driver is placed in the "misc" directory, following the practice
of other PCI endpoint bus drivers.

Note: to work correctly, this series depends on this:
  https://lore.kernel.org/lkml/20260910021919.3421449-1-elder@xxxxxxxxxxxx/

Between version 1 and version 2:
- Updated the block diagram in the binding to include BAR2 and SRAM
- Use KBUILD_MODNAME for the driver name
- Removed bogus initialization of pci_driver->driver field
- Added the third patch, which defines pci-ep-bus DTS information.
- Now based on the Qualcomm for-next branch

Version 1 is available here:
