This series adds support for xHCI on NVIDIA Tegra SoCs. This includes: - patches 1, 2, and 3: minor cleanups for mailbox framework and xHCI, - patches 4 and 5: adding an MFD driver for the XUSB cmoplex, - patches 6 and 7: adding a driver for the mailbox used to communicate with the xHCI controller's firmware, and - patches 8 and 9: adding a xHCI host-controller driver. The addition of USB PHY support to the XUSB padctl driver has been dropped from v7. Thierry will be posting those patches later. Given the many compile and run-time dependencies in this series, it is probably best if the first 3 patches are picked up by the relevant maintainers in topic branches so that the remainder of the series can go through the Tegra tree. Tested on Jetson TK1 and Nyan-Big with a variety of USB2.0 and USB3.0 memory sticks and ethernet dongles. This has also been tested, with additional out-of-tree patches, on a Tegra132-based board. Based on v4.1-rc1. A branch with the entire series is available at: https://github.com/abrestic/linux/tree/tegra-xhci-v7 Changes from v6: - Dropped PHY changes from series. Will be posted later by Thierry. - Added an MFD device with the mailbox and xHCI host as sub-devices. Changes from v5: - Addressed review comments from Jassi and Felipe. Changes from v4: - Made USB support optional in padctl driver. - Made usb3-port a pinconfig property again. - Cleaned up mbox_request_channel() error handling and allowed it to defer probing (patch 3). - Minor xHCI (patch 1) and mailbox framework (patch 2) cleanups suggested by Thierry. - Addressed Thierry's review comments. Changes from v3: - Fixed USB2.0 flakiness on Jetson-TK1. - Switched to 32-bit DMA mask for host. - Addressed Stephen's review comments. Chagnes from v2: - Dropped mailbox channel specifier. The mailbox driver allocates virtual channels backed by the single physical channel. - Added support for HS_CURR_LEVEL adjustment pinconfig property, which will be required for the Blaze board. - Addressed Stephen's review comments. Changes from v1: - Converted mailbox driver to use the common mailbox framework. - Fixed up host driver so that it can now be built and used as a module. - Addressed Stephen's review comments. - Misc. cleanups.
