This includes... 1. An update to the altmode sysfs group after registration to make "active" writable. 2. A change to the ucsi_partner_task delay when queuing ucsi_check_altmodes to prevent it from running before other discovery functions. 3. An update to always define a number of alternate modes for partners and plugs. Not related to AP driven altmode entry, there is an additional fix for a null derefrence in this series. I tested the series on a ChromeOS v6.8 kernel merged with usb-testing. That build had some additinal patches to enable a PPM in ChromeOS. Let me know if you have any questions. Thanks, Jameson Changes in V5: - Fixed signed off by line order. Changes in V4: - Updates to the commit messages. Changes in V3: - Returns typec_port_register_altmode call from ucsi_register_displayport when CONFIG_TYPEC_DP_ALTMODE is not enabled. Changes in V2: - Checks for error response from ucsi_register_displayport when registering DisplayPort alternate mode.
