Hi Heikki, Tzung-Bi et al, This patch series adds support for alternate mode entry for the cros-ec-typec driver for Displayport and Thunderbolt. Thunderbolt support is added by adapting an RFC Heikki had posted previously: https://lore.kernel.org/linux-usb/20191230152857.43917-1-heikki.krogerus@xxxxxxxxxxxxxxx/ A few comments on the series: * The cros-ec interface will not accept any VDOs/VDMs so we simply ignore any configurations we are passed (i.e. DPConfigure). This means the sysfs control of DP lanes won't work. * ChromeOS has two modes of operation for alt-modes: entirely EC driven or AP-driven from userspace (via the typec daemon). Thus, we never expect the kernel alt-mode drivers to auto-enter modes. This was tested on kernel 6.6 with a ChromeOS Brya device and compile tested against linux-usb (with allmodconfig). Thanks, Abhishek Abhishek Pandit-Subedi (7): usb: typec: altmode_match should handle TYPEC_ANY_MODE usb: typec: intel_pmc_mux: Null check before use usb: typec: Auto enter control for alternate modes platform/chrome: cros_ec_typec: Update partner altmode active platform/chrome: cros_ec_typec: Displayport support platform/chrome: cros_ec_typec: Thunderbolt support platform/chrome: cros_ec_typec: Disable auto_enter Heikki Krogerus (1): usb: typec: Add driver for Thunderbolt 3 Alternate Mode Documentation/ABI/testing/sysfs-bus-typec | 9 + MAINTAINERS | 5 +- drivers/platform/chrome/Makefile | 3 + drivers/platform/chrome/cros_ec_typec.c | 55 ++- drivers/platform/chrome/cros_ec_typec.h | 1 + drivers/platform/chrome/cros_typec_altmode.h | 48 +++ .../platform/chrome/cros_typec_displayport.c | 247 ++++++++++++++ .../platform/chrome/cros_typec_thunderbolt.c | 184 ++++++++++ drivers/usb/typec/altmodes/Kconfig | 9 + drivers/usb/typec/altmodes/Makefile | 2 + drivers/usb/typec/altmodes/displayport.c | 6 +- drivers/usb/typec/altmodes/thunderbolt.c | 322 ++++++++++++++++++ drivers/usb/typec/class.c | 34 +- drivers/usb/typec/mux/intel_pmc_mux.c | 9 +- include/linux/usb/typec.h | 2 + include/linux/usb/typec_altmode.h | 2 + 16 files changed, 918 insertions(+), 20 deletions(-) create mode 100644 drivers/platform/chrome/cros_typec_altmode.h create mode 100644 drivers/platform/chrome/cros_typec_displayport.c create mode 100644 drivers/platform/chrome/cros_typec_thunderbolt.c create mode 100644 drivers/usb/typec/altmodes/thunderbolt.c -- 2.46.0.792.g87dc391469-goog
