> This series adds PCIe support for Tegra20, Tegra30 and Tegra124. The
> size is mostly due to the large number of infrastructure that's added
> (libfdt, Tegra specific drivers required by the PCIe driver). In this
> version I've included all patches that were previously split into
> three separate series. Spreading them over multiple series is
> probably not worth it since there might be some dependencies between
> them and only the end result gives a completely working setup.
>
> Patch 1 adds a %pa modifier to printf() to print physical addresses.
> This is required to allow code to output such addresses irrespective
> of whether a 64 bit or 32 bit architecture is built for.
>
> Patches 2-7 add various FDT helpers to make it easier to parse
> complex device trees.
>
> Patch 8 is a minor cleanup to the PCI command that prevents a spew of
> error messages if a bus does not exist. Patch 9 modifies the PCI
> enumeration code to honor theh restrictions encoded within a host
> controller driver's pci_ski_dev() implementation. This is required to
> prevent exceptions from the NVIDIA Tegra PCIe controller.
>
> Patch 10 imports the pr_fmt() macro used within the Linux kernel to
> reduce the number of characters consumed by literal strings by
> allowing a source file to specify a prefix or suffix that should be
> applied to all format strings in the file. It is currently used by
> the debug() and error() macros.
>
> Patches 11-14 are some cleanup and refactoring of I2C core code, the
> addition of a higher level API that makes it easier for I2C client
> drivers to talk to devices. The Tegra I2C driver now implements
> i2c_get_bus_num_fdt() to obtain bus numbers corresponding to a DT
> node.
>
> Patch 15 implements a driver for the AS3722 PMIC used on the Venice2
> and Jetson TK1 boards.
>
> Patches 16-21 are preparatory work for the Tegra PCIe controller.
> They add missing clock driver functionality as well as drivers for
> the Tegra powergate and XUSB pad controller blocks.
>
> Patch 22 adds the PCIe controller driver for Tegra20, Tegra30 and
> Tegra124.
>
> Device tree nodes and configurations options to enable PCIe on the
> TrimSlice (Tegra20), Beaver, Cardhu (Tegra30) and Jetson TK1
> (Tegra124) boards are added in patches 23-31.
>
> Patches 32-35 implement non-cached memory support that will be used
> in the last batch of patches to implement more reliable packet
> transfers in the r8169 driver. Patch 36 enables non-cached memory
> support on Tegra.
>
> Finally, patches 37-40 implement non-cached memory support and
> various fixes in the r8169 driver and add support for the revision of
> the NIC found on the Jetson TK1.
>
> The above boards all have an ethernet NIC connected to PCIe, which is
> what I tested with.

Am I right in thinking there will be a V3 series, at least of the part
not already awaiting upstream ? If so, maybe it should all be delegated
to a single custodian -- right now it is split over five custodians
(although part of it -- so that all of it is applied in one go without
"foreign" patches getting in between.
Amicalement,

Albert.
