[PATCH 0/4] clk: introduce TC9564 clock and reset

[Alex Elder <elder@riscstar.com>]

This series adds support for the clock and reset controller present
within the TC9564 SoC.

This SoC attaches to a host system via PCIe.  It includes a PCIe
switch with three downstream ports.  To one of these ports an
embedded PCIe endpoint is attached, and it implements two PCI
functions.  BAR 4 for both of these PCI functions provides access
to the registers that enable or disable a number of clock signals,
and assert or deassert a set of reset lines.

The TC9564 PCI functions provide PCI endpoint buses via devicetree.
This allows a PCI function to use devicetree to define subordinate
devices accessible using one or more of the function's BARs.  The
clock/reset driver binds with a device defined this way.  Only one
of the two PCI functions is permitted to define the clock/reset
device node.
