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.

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.

OK. I looked at the series and you should really be using the pmic framework. I've pushed a branch to 'dm/norrin-working' that changes it (see the as3722 patch near the top). See tps65090 for an example. It should avoid any messing with I2C. Then, when the new PMIC framework rolls out your code will ride along for free. Plus you can drop the i2c additions that way. Also, there is a clock function that seems to bash various registers - tegra_plle_enable. I think this should use clock_set_rate() - i.e. build in support for the new clock rather than creating a parallel function. The power gate stuff looks good. Are you planning to replace the power gate code in arch/arm/cpu/arm720t/tegra124/cpu.c and the like? The only minor issue I see is the availability of get_timer() - but in tegra_powergate_set() 25ms seems like a very long delay to me anyway. If there's any interest I can push a branch with the work-in-progress I2C DM patches, perhaps it could serve as the basis if someone else wanted to continue with that effort.

[U-Boot] [PATCH v2 00/40] ARM: tegra: Add PCIe support
From: Thierry Reding tred...@nvidia.com 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.
