This series adds PCIe support for Tegra20, Tegra30 and Tegra124. The size is mostly due to the large number of infrastructure that's added (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.
Some patches have already been applied to this series.
Patch 1 implements a driver for the AS3722 PMIC used on the Venice2 and Jetson TK1 boards.
Patches 2-7 are preparatory work for the Tegra PCIe controller. They add missing clock driver functionality as well as drivers for the Tegra powergat and XUSB pad controller blocks.
Patch 8 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 9-17.
Patch 18 implements 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 19 enables non-cached memory support on Tegra.
(Note from Simon: These patches may have already been applied in the ARM tree, but I can't see them there).
Finally, patches 20-23 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.
Note from Simon: I have:
- rebased this on top of the I2C driver model series
- dropped the I2C framework patches
- adjust the PMIC driver and code that calls it to use driver mode
- tested the I2C changes on Jetson-TK1
Changes in v4:
- Use const unsigned for bus and address
- Insert missing word 'to' in a comment
- Fix typo in commit message
Changes in v3:
- Use driver model for the PMIC
- Use driver model to access the PMIC
- Use driver model to access the PMIC
- Avoid build error with noncached_init() when the dcache is disabled
- Remove cache-line size warning if dcache is disabled

The I2C things have hit mainline now so this series is ready now.
There is a trivial fix on the 'Enable non-cached memory' patch - you can add the CONFIG immediately below CONFIG_SYS_NONCACHED_MEMORY perhaps.
I pushed my take on it to u-boot-dm/pcie-working in case it helps.
