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. 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 Tegra132 and Tegra210 based boards. Based on v4.1-rc2. A branch with the entire series is available at: https://github.com/abrestic/linux/tree/tegra-xhci-v8 Cc: Jon Hunter <jonathanh@xxxxxxxxxx> Changes from v7: - Move non-shared resources into child nodes of MFD. - Fixed a couple of mailbox driver bugs. 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.
