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 a driver for the mailbox used to communicate with the xHCI controller's firmware, - patches 6 and 7: extending the XUSB pad controller driver to support the USB PHY types (UTMI, HSIC, and USB3), - patches 8 and 9: adding a xHCI host-controller driver, and - patches 10, 11, and 12: updating the relevant DT files. The mailbox driver (patch 5) has a compile-time dependency on patch 2 and a run-time dependency on patch 3. Both the PHY (patch 7) and host (patch 9) drivers have compile-time dependencies on the mailbox driver. The host driver also has a run-time dependency on patch 1. Because of this, this entire series should probably go through the Tegra tree. Patches 11 and 12 should probably not be merged until the controller firmware [0] lands in linux-firmware since they disable the EHCI controllers. Tested on Venice2, Jetson TK1, and 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 v3.18-rc6. A branch with the entire series is available at: https://github.com/abrestic/linux/tree/tegra-xhci-v6 Notes: - HSIC support is mostly untested and I think there are still some issues to work out there. I do have a Tegra124 board with a HSIC hub so I'll try to sort those out later. - The XUSB padctl driver doesn't play nice with the existing Tegra USB2.0 PHY driver, so all ports should be assigned to the XHCI controller. Based on work by: a lot of people, but from what I can tell from the L4T tree [1], the original authors of the Tegra xHCI driver are: Ajay Gupta <ajayg@xxxxxxxxxx> Bharath Yadav <byadav@xxxxxxxxxx> [0] https://patchwork.ozlabs.org/patch/400110/ [1] git://nv-tegra.nvidia.com/linux-3.10.git 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.
