iio: cros_ec_sensors: add cros_ec_activity driver

2025-06-26T18:32:51+00:00

ChromeOS EC can report activity information derived from the accelerometer: - Reports on-body/off-body as a proximity event. - Reports significant motion as an activity event. This new sensor is a virtual sensor, included only when the EC firmware is compiled with the appropriate module.

platform/chrome: add PD_EVENT_INIT bit definition

2025-02-14T08:29:07+00:00

Update cros_ec_commands.h to include a definition for PD_EVENT_INIT. On platforms supporting UCSI, this host event type is sent when the PPM initializes.

platform/chrome: Update ChromeOS EC header for UCSI

2025-01-03T10:14:17+00:00

Add EC host commands for reading and writing UCSI structures in the EC. The corresponding kernel driver is cros-ec-ucsi. Also update PD events supported by the EC.

media: cros-ec-cec: Get number of CEC ports from EC

2023-09-27T07:39:55+00:00

Add a new CEC port count host command and use it to query the number of CEC ports from the EC. If the host command is not supported then it must be old EC firmware which only supports one port, so fall back to assuming one port. This patch completes support for multiple ports in cros-ec-cec.

media: cros-ec-cec: Support receiving messages from multiple ports

2023-09-27T07:39:54+00:00

Currently, received messages are sent from the EC in the cec_message MKBP event. Since the size of ec_response_get_next_data_v1 is 16 bytes, which is also the maximum size of a CEC message, there is no space to add a port parameter. Increasing the size of ec_response_get_next_data_v1 is an option, but this would increase EC-kernel traffic for all MKBP event types. Instead, use an event to notify that data is ready, and add a new read command to read the data. For backwards compatibility with old EC firmware, continue to handle cec_message events as well.
