The ChromeOS EC is expected to implement UCSI Platform Policy Manager (PPM). --- Changes in v5: - Increased WRITE_TMO_MS to 5000. - Replaced DRV_NAME with KBUILD_MODNAME. - Added comments for WRITE_TMO_MS and MAX_EC_DATA_SIZE defines. - Refactored cros_ucsi_async_control() to dynamically allocate memory for a message to EC instead of allocating the message on stack. - Replaced type names uint*_t with u*. - Removed ret variable in cros_ucsi_work(). - Updated ucsi_operations interface to align with changes introduced in v6.11. - Replaced test_bit() with test_and_clear_bit() in cros_ucsi_work(). - Added trace events in commit "usb: typec: cros_ec_ucsi: Add trace events". - Added netlink in commit "usb: typec: cros_ec_ucsi: Add netlink" for debugging and testing puropses. - Link to v4: https://lore.kernel.org/all/CAB2FV=6We88NrvN8NZYt8NkMFH9N_ZBGyUWVUpGwPdja2X_+NA@mail.gmail.com/T/ Changes in v4: - Setup notifications before calling ucsi_register. - Cancel work before destroying driver data. - Link to v3: https://lore.kernel.org/r/20240403-public-ucsi-h-v3-0-f848e18c8ed2@chromium.org Changes in v3: - Moved driver from platform/chrome to usb/typec/ucsi. - Used id_table instead of MODULE_ALIAS. - Split EC header changes into seperate commit. - Fixes from additional internal reviews and kernel bot warnings. - Link to v2: https://lore.kernel.org/r/20240325-public-ucsi-h-v2-0-a6d716968bb1@chromium.org Changes in v2: - No code or commit message changes. - Added drivers/platform/chrome maintainers for review. - Link to v1: https://lore.kernel.org/r/20240325-public-ucsi-h-v1-0-7c7e888edc0a@chromium.org Abhishek Pandit-Subedi (2): usb: typec: cros_ec_ucsi: Use complete instead of resume mfd: cros_ec: Don't load charger with UCSI Pavan Holla (4): platform/chrome: Update ChromeOS EC header for UCSI platform/chrome: Update EC feature flags usb: typec: ucsi: Implement ChromeOS UCSI driver mfd: cros_ec: Load cros_ec_ucsi on supported ECs Łukasz Bartosik (2): usb: typec: cros_ec_ucsi: Add trace events usb: typec: cros_ec_ucsi: Add netlink MAINTAINERS | 10 + drivers/mfd/cros_ec_dev.c | 25 +- drivers/usb/typec/ucsi/Kconfig | 13 + drivers/usb/typec/ucsi/Makefile | 3 + drivers/usb/typec/ucsi/cros_ec_ucsi_main.c | 351 ++++++++++++++++++ drivers/usb/typec/ucsi/cros_ec_ucsi_nl.c | 87 +++++ drivers/usb/typec/ucsi/cros_ec_ucsi_nl.h | 52 +++ drivers/usb/typec/ucsi/cros_ec_ucsi_trace.h | 92 +++++ .../linux/platform_data/cros_ec_commands.h | 54 ++- 9 files changed, 683 insertions(+), 4 deletions(-) create mode 100644 drivers/usb/typec/ucsi/cros_ec_ucsi_main.c create mode 100644 drivers/usb/typec/ucsi/cros_ec_ucsi_nl.c create mode 100644 drivers/usb/typec/ucsi/cros_ec_ucsi_nl.h create mode 100644 drivers/usb/typec/ucsi/cros_ec_ucsi_trace.h
