This series is comprised of some code that was previously sent
separately. It now incorporates a new system controller driver
that advertises clock and reset functionality, as well as regmap
access to its address range. This combination is being treated
as a new series. (Details of previous versions are below.)
The Toshiba TC9564 is an SoC that 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 that implements
two PCI functions. BAR 4 for both PCI functions provides access to
registers controlling blocks within the SoC.
The system controller driver adds the clock and reset devices
using the mfd_add_devices() interface. The clocks and resets
are implemented by drivers included in this series.
Toshiba TC9564 bindings and DTS should be posted completely. We spent
great amount of time on discussing already and I pointed more than once
that big picture is missing.
You are not describing here parts of a SoC.
You are describing one, single device how the host sees it and DT
maintainers (and writing bindings) ask for complete picture in such cases.
Best regards,
Krzysztof
