thunderbolt: cap: Fix kernel-doc formatting issue

2021-01-28T09:33:18+00:00

Fixes the following W=1 kernel build warning(s): drivers/thunderbolt/cap.c:189: warning: Function parameter or member 'sw' not described in 'tb_switch_find_cap' Cc: Andreas Noever Cc: Michael Jamet Cc: Yehezkel Bernat Cc: linux-usb@vger.kernel.org Signed-off-by: Lee Jones Signed-off-by: Mika Westerberg

thunderbolt: Introduce tb_switch_next_cap()

2020-09-03T09:21:07+00:00

This is similar to tb_port_next_cap() but instead allows walking capability list of a switch (router). Convert tb_switch_find_cap() and tb_switch_find_vse_cap() to use this as well. Signed-off-by: Mika Westerberg Reviewed-by: Greg Kroah-Hartman

thunderbolt: Introduce tb_port_next_cap()

2020-09-03T09:21:07+00:00

This function is useful for walking port config space (adapter) capability lists. Convert the tb_port_find_cap() to use this as well. Signed-off-by: Mika Westerberg Reviewed-by: Greg Kroah-Hartman

thunderbolt: Move struct tb_cap_any to tb_regs.h

2020-09-03T09:21:07+00:00

This structure will be needed by the debugfs implementation so make it available outside of cap.c. While there add kernel-doc comments to the structure. Signed-off-by: Mika Westerberg Reviewed-by: Greg Kroah-Hartman

thunderbolt: Make tb_switch_find_cap() available to other files

2019-12-18T14:40:36+00:00

We need to find switch capabilities in order to implement TMU support so make it available to other files as well. Signed-off-by: Rajmohan Mani Signed-off-by: Mika Westerberg Link: https://lore.kernel.org/r/20191217123345.31850-7-mika.westerberg@linux.intel.com Signed-off-by: Greg Kroah-Hartman

thunderbolt: Expand controller name in tb_switch_is_xy()

2019-11-02T09:13:31+00:00

For a casual reader tb_switch_is_cr() does not tell much so instead spell out the full controller name in the function name. For example tb_switch_is_cr() becomes tb_switch_is_cactus_ridge() which is easier to understand. Signed-off-by: Mika Westerberg

thunderbolt: Add dummy read after port capability list walk on Light Ridge

2019-04-18T08:18:51+00:00

Light Ridge has an issue where reading the next capability pointer location in port config space the read data is not cleared. It is fine to read capabilities each after another so only thing we need to do is to make sure we issue dummy read after tb_port_find_cap() is finished to avoid the issue in next read.

thunderbolt: Enable TMU access when accessing port space on legacy devices

2019-04-18T08:18:51+00:00

Light Ridge and Eagle Ridge both need to have TMU access enabled before port space can be fully accessed so make sure it happens on those. This allows us to get rid of the offset quirk in tb_port_find_cap(). Signed-off-by: Mika Westerberg

thunderbolt: Add Intel as copyright holder

2018-10-02T22:52:08+00:00

Intel has done pretty major changes to the driver and we continue to do so in the future as well. Add Intel as copyright holder of the files we have done changes. While there drop "Cactus Ridge" from the headers because this driver works also with other Thunderbolt controllers. No functional changes intended.
