Revert "thunderbolt: Hide authorized attribute if router does not support PCIe tunnels"

2021-07-27T16:14:25Z

This reverts commit 6f3badead6a078cf3c71f381f9d84ac922984a00. It turns out bolt depends on having authorized attribute visible under each device. Hiding it makes bolt crash as several people have reported on various bug trackers. For this reason revert the commit.

thunderbolt: test: Reinstate a few casts of bitfields

2021-06-25T17:31:03Z

Partially revert "thunderbolt: test: Remove some casts which are no longer required". It turns out that typeof() doesn't support bitfields, so these still need to be cast to the appropriate enum. The only mention of typeof() and bitfields I can find is in the proposal to standardise them: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2619.htm This was caught by the kernel test robot: https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org/thread/FDKBHAV7QNLNFU5NBI2RKV56DWDSOLGM/ Fixes: 8f0877c26e4b ("thunderbolt: test: Remove some casts which are no longer required") Reported-by: kernel test robot Signed-off-by: David Gow Signed-off-by: Shuah Khan

thunderbolt: test: Remove some casts which are no longer required

2021-06-23T22:40:18Z

With some of the stricter type checking in KUnit's EXPECT macros removed, several casts in the thunderbolt KUnit tests are no longer required. Remove the unnecessary casts, making the conditions clearer. Signed-off-by: David Gow Acked-by: Mika Westerberg Reviewed-by: Brendan Higgins Signed-off-by: Shuah Khan

thunderbolt: Fix DROM handling for USB4 DROM

2021-06-15T10:51:07Z

DROM for USB4 host/device has a shorter header than Thunderbolt DROM header. This patch addresses host/device with USB4 DROM (According to spec: Universal Serial Bus 4 (USB4) Device ROM Specification, Rev 1.0, Feb-2021). While there correct the data_len field to be 12 bits and rename __unknown1 to reserved following the spec. Signed-off-by: Gil Fine Signed-off-by: Mika Westerberg

thunderbolt: Add support for Intel Alder Lake

2021-06-11T08:42:54Z

Alder Lake has the same integrated Thunderbolt/USB4 controller as Intel Tiger Lake. By default it is still using firmware based connection manager so we can use most of the Tiger Lake flows. Add the Alder Lake PCI IDs to the driver list of supported devices. Signed-off-by: Azhar Shaikh Reviewed-by: Yehezkel Bernat Signed-off-by: Mika Westerberg

thunderbolt: Poll 10ms for REG_FW_STS_NVM_AUTH_DONE to be set

2021-06-11T08:42:54Z

In Intel Tiger Lake and beyond it takes some time after the force power is set until the firmware connection manager is ready. So instead of reading it once we poll it for 10ms before giving up. Signed-off-by: Gil Fine Reviewed-by: Yehezkel Bernat Signed-off-by: Mika Westerberg

thunderbolt: Add device links only when software connection manager is used

2021-06-11T08:42:54Z

We only need to set up the device links when software connection manager path is used. The firmware connection manager does not need them and if they are present they may even cause problems. Reviewed-by: Yehezkel Bernat Signed-off-by: Mika Westerberg
