X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9b6db9a3a675fc2f33b587a9909dcef20c4b3794;p=linux.git Merge tag 'thunderbolt-for-v6.7-rc1' of git://git./linux/kernel/git/westeri/thunderbolt into usb-next Mika writes: thunderbolt: Changes for v6.7 merge window This includes following USB4/Thunderbolt changes for the v6.7 merge window: - Configure asymmetric link if the DisplayPort bandwidth requires so - Enable path power management packet support for USB4 v2 routers - Make the bandwidth reservations to follow the USB4 v2 connection manager guide suggestions - DisplayPort tunneling improvements - Small cleanups and improvements around the driver. All these have been in linux-next with no reported issues. * tag 'thunderbolt-for-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/westeri/thunderbolt: (25 commits) thunderbolt: Fix one kernel-doc comment thunderbolt: Configure asymmetric link if needed and bandwidth allows thunderbolt: Add support for asymmetric link thunderbolt: Introduce tb_switch_depth() thunderbolt: Introduce tb_for_each_upstream_port_on_path() thunderbolt: Introduce tb_port_path_direction_downstream() thunderbolt: Set path power management packet support bit for USB4 v2 routers thunderbolt: Change bandwidth reservations to comply USB4 v2 thunderbolt: Make is_gen4_link() available to the rest of the driver thunderbolt: Use weight constants in tb_usb3_consumed_bandwidth() thunderbolt: Use constants for path weight and priority thunderbolt: Add DP IN added last in the head of the list of DP resources thunderbolt: Create multiple DisplayPort tunnels if there are more DP IN/OUT pairs thunderbolt: Log NVM version of routers and retimers thunderbolt: Use tb_tunnel_xxx() log macros in tb.c thunderbolt: Expose tb_tunnel_xxx() log macros to the rest of the driver thunderbolt: Use tb_tunnel_dbg() where possible to make logging more consistent thunderbolt: Fix typo of HPD bit for Hot Plug Detect thunderbolt: Fix typo in enum tb_link_width kernel-doc thunderbolt: Fix debug log when DisplayPort adapter not available for pairing ... --- 9b6db9a3a675fc2f33b587a9909dcef20c4b3794 diff --cc drivers/thunderbolt/switch.c index bd5815f8f23bd,e09ac36f71a7a..1e15ffa792955 --- a/drivers/thunderbolt/switch.c +++ b/drivers/thunderbolt/switch.c @@@ -2721,17 -2811,10 +2811,17 @@@ static int tb_switch_lane_bonding_enabl up = tb_upstream_port(sw); down = tb_switch_downstream_port(sw); - if (!tb_port_is_width_supported(up, TB_LINK_WIDTH_DUAL) || - !tb_port_is_width_supported(down, TB_LINK_WIDTH_DUAL)) + if (!tb_port_width_supported(up, TB_LINK_WIDTH_DUAL) || + !tb_port_width_supported(down, TB_LINK_WIDTH_DUAL)) return 0; + /* + * Both lanes need to be in CL0.
