platform/chrome: cros_ec_trace: Fix format warnings

2021-08-31T00:46:55+00:00

Fix printf format issues in new tracing events. Fixes: 814318242687 ("platform/chrome: cros_ec_trace: Add fields to command traces") Signed-off-by: Gwendal Grignou Link: https://lore.kernel.org/r/20210830180050.2077261-1-gwendal@chromium.org Signed-off-by: Benson Leung

platform/chrome: cros_ec_typec: Use existing feature check

2021-08-23T17:24:46+00:00

Replace the cros_typec_feature_supported() function with the pre-existing cros_ec_check_features() function which does the same thing. Signed-off-by: Prashant Malani Link: https://lore.kernel.org/r/20210803173619.91539-2-pmalani@chromium.org Signed-off-by: Benson Leung

platform/chrome: cros_ec_proto: Send command again when timeout occurs

2021-07-26T23:15:55+00:00

Sometimes kernel is trying to probe Fingerprint MCU (FPMCU) when it hasn't initialized SPI yet. This can happen because FPMCU is restarted during system boot and kernel can send message in short window eg. between sysjump to RW and SPI initialization.

platform/chrome: sensorhub: Add trace events for sample

2021-07-26T11:24:46+00:00

Add trace event to report samples and their timestamp coming from the EC. It allows to check if the timestamps are correct and the filter is working correctly without introducing too much latency. To enable these events: cd /sys/kernel/debug/tracing/ echo 1 > events/cros_ec/enable echo 0 > events/cros_ec/cros_ec_request_start/enable echo 0 > events/cros_ec/cros_ec_request_done/enable echo 1 > tracing_on cat trace_pipe Observe event flowing: irq/105-chromeo-95 [000] .... 613.659758: cros_ec_sensorhub_timestamp: ... irq/105-chromeo-95 [000] .... 613.665219: cros_ec_sensorhub_filter: dx: ...

platform/chrome: cros_ec_lpc: Use DEFINE_MUTEX() for mutex lock

mutex lock can be initialized automatically with DEFINE_MUTEX() rather than explicitly calling mutex_init(). Reported-by: Hulk Robot Signed-off-by: Ye Bin Signed-off-by: Enric Balletbo i Serra Link: https://lore.kernel.org/r/20210409095138.2293869-1-yebin10@huawei.com

platform/chrome: cros_usbpd_notify: Listen to EC_HOST_EVENT_USB_MUX host event

2021-04-21T07:40:37+00:00

On system that use ACPI, cros_usbpd_notify gets notifications of USB MUX host event same as PD host events [1]. But currently on system that use DT, the driver only listen on EC_HOST_EVENT_PD_MCU. Add EC_HOST_EVENT_USB_MUX to the list of host events, so we have same behavior on all platforms.

platform/chrome: cros_ec_typec: Add DP mode check

2021-04-21T07:33:35+00:00

There are certain transitional situations where the dp_mode field in the PD_CONTROL response might not be populated with the right DP pin assignment value yet. Add a check for that to avoid sending an invalid value to the Type C mode switch.

platform/chrome: cros_ec_typec: Handle hard reset

2021-04-20T17:35:42+00:00

The Chrome Embedded Controller (EC) generates a hard reset type C event when a USB Power Delivery (PD) hard reset is encountered. Handle this event by unregistering the partner and cable on the associated port and clearing the event flag.
